It can be argued that most fitness trackers users are very health conscious. Some are training for a race, some are professional athletes, and some just have fitness goals that they are working towards. However, there is an increasing amount of fitness tracker wearers who are tracking their physical state because of a medical condition that they have.
It can be argued that most fitness trackers users are very health conscious. Some are training for a race, some are professional athletes, and some have fitness goals that they are working towards. Yet, there is an increasing amount of fitness tracker wearers who are tracking their physical state because of a medical condition that they have. There may be no medical condition as scary as a heart condition, which is why many are asking, “Can you wear a fitness tracker with a pacemaker?” The answer is yes. There is little to no risk of wearing a fitness tracker with a pacemaker. But, it is understandable that some people may question this; read on to find out why.
Devices With Little to No Threat
There are some devices that have made a small impact on the accuracy of a pacemaker or implantable cardioverter defibrillators (ICDs). Here is a list of some of the devices like fitness trackers that make people wonder if fitness trackers are safe.
Cell phones are not a huge problem with pacemakers or ICDs, but the frequencies emitted from the antenna have been known to cause them to be less reliable if positioned too close to the pacemaker. According to the American Heart Association, you can still use cell phones with a pacemaker, providing you try to use them on the ear furthest away from your pacemaker.
Since many fitness trackers are smart watches and have a cell phone component with them, many people wonder if they will cause the same issue. Even though there haven’t been any reported problems with smartwatches concerning pacemakers and ICD accuracy, it is always best to exercise caution and keep your fitness tracker at least 6 inches away from your pacemaker as often as possible. If you happen to lay your hand on your chest when sleeping, you may want to consider removing your fitness tracker before bed.
Fitness trackers often will use Bluetooth to communicate with your mobile device or computer. The American Heart Association states that these “headsets don’t appear to interfere with ICDs or pacemakers.”
Although MP3 players do not pose a threat to a pacemaker or ICD, the American Heart Association says that “Most MP3 headphones contain a magnetic material that can interfere with ICDs and pacemakers. Both earbud and clip-on headphones can cause interference.” So while your fitness tracker may not cause any problems, if you are using them in conjunction with headphones, be wary of where you place your headphones. You should never put them near your chest and try to keep them at least 6 inches away from your device.
Computers and Other Electronic Devices
Most consumer products, at least in the United States, have undertaken rigorous testing to make sure that it is the safest product that it can be. And according to the American Heart Association, “In general, consumer appliances and electronics don’t affect the performance of ICDs and pacemakers. On rare occasions, some of these devices may inhibit pacemakers by a single beat. But the pacemaker’s regular signals are quickly restored.”
So what does affect a pacemaker, and why would a fitness tracker not make the list of dangerous incompatible technology? The reason why pacemakers and ICD’s react poorly when they are near certain pieces of equipment are based on the frequency that the technology runs on, the transmitting power, and antennae if there are any.
How Pacemakers Work
To understand how any piece of technology could affect your pacemaker or ICD, you have to first understand how it works. According to the National Heart, Lung, and Blood Institute (NHLBI), pacemakers are controlled by electrodes that measure your heart beats and function. If it senses that your heart is at an unhealthy range for your condition, then it will send electricity to your heart to help it pulse.
So a pacemaker is constantly “listening” for electromagnetic frequencies (EMFs). EMFs are everywhere at different frequencies and different strengths, so a pacemaker has to be discerning. The Earth’s electromagnetic field is constantly producing EMFs, so they are quite literally inescapable. Though, many frequencies are so low that they aren’t read by a pacemaker and many EMFs produced by appliances and technology are transmitted at a far enough distance from your pacemaker that it doesn’t affect a pacemaker.
Someone who has a pacemaker can be in the same room with several appliances and pieces of technology that emit electromagnetic frequencies and be just fine. Even a distance as small as 6 to 12 inches can be far enough away that it doesn’t affect the device. In fact, there are some pacemakers that have a ceramic coating that will protect the device even more from foreign EMTs that might affect the function of the device.
So though pacemakers are constantly measuring electromagnetic frequencies, they are also fairly advanced and can tell the difference in most cases between the pulses from the heart and the frequencies from the surroundings.
How Fitness Trackers Work
Like most technological devices, fitness trackers do produce EMFs but they are at a very low frequency. Cell phones, which also have a low frequency have a much higher frequency than fitness trackers and are deemed safe to use as long as it is positioned at least six inches away from the pacemaker.
Most people assume that fitness trackers measure your heart rate using electricity similar to the leads that produce electricity for an EKG, however this is not how most trackers measure heart rates. Fitness trackers instead use an LED light to illuminate the capillaries under the skin and detect how fast the heart is beating based on how much like is reflected back to the sensors. This method is called photoplethysmography, and it does not affect pacemakers.
The Apple Watch
Most of the fitness trackers on the market are harmless or pose little risk to the accuracy and functions of your pacemaker or ICD, but not all. The Apple Watch states clearly in its manual that the “Apple Watch contains components and radios that emit electromagnetic fields. Apple Watch, some of the bands, the Apple Watch Magnetic Charging Cable, and the Apple Watch Magnetic Charging Dock contain magnets. These electromagnetic fields and magnets may interfere with medical devices, such as pacemakers and defibrillators.”
So, someone who has an Apple watch and a pacemaker or ICD should exercise more caution with this product. Apple does not go into all the functions that use the electromagnetic fields, however, the series 4 watch user manual did not have quite the same wording and didn’t mention radio or electromagnetic fields, just that some components contained magnets. So perhaps the EKG feature in the newer series of Apple Watches does pose a bit more of a risk than the older series prior to the EKG function.
Someone with a pacemaker should absolutely not use the EKG function in the Apple Watch unless cleared with a doctor.
Consult A Doctor
It is difficult to be 100 percent sure of the safety of a product, especially when there are new fitness trackers on the market all the time. The technology in both pacemakers and in fitness trackers are constantly changing and improving and how they work together may change in the future.
The best course of action would be to contact your cardiologist about your particular fitness tracker you are considering buying. This does get a little tricky as your cardiologist may not stay up with the latest technology, however, he or she should be able to figure out if the fitness tracker is safe or not based on other similar products.
If you are ever unsure of a product, start with your cardiologist. If you are still unsure after given the all clear, then exercise caution and keep your device at least 6 inches away from your chest at all times. Fitness trackers can be an amazing tool to keep an eye on your health, especially if you have a heart condition.
Signs of Pacemaker Failure
In rare circumstances, your pacemaker may start to fail. This could be due to EMF interference, low battery life, or pulling on leads. If you do have a pacemaker and you are worried that it might begin to fail, then be on the lookout for these symptoms:
Shortness of Breath
Overly Slow or Fast Heart Rate
Twitching Muscles in Chest or Abdomen
If you have any of those symptoms and you already have a pacemaker, you may want to consult your physician. Your doctor will be able to test your pacemaker and will know if it may be in the time window for a new battery. Of course, if you feel any of these symptoms to the point where you are concerned about your immediate health, then call 911 or have a friend take you to the emergency room.
According to the American Heart Association, there are 3 million people worldwide with a pacemaker and 600,000 pacemakers are placed yearly. These people have more cause to track their health than the average person, so it is important that fitness trackers are safe for this demographic.
Though your fitness tracker should never replace your medical consultations with a physician, it can be helpful to make sure that you are exercising in a safe range and help you keep an eye on your heart’s performance.
Most fitness trackers are known to track the basics such as steps taken, calories burnt and heart rate. Recently, I’ve started to get more into lifting weights whilst at the gym. People don’t realise it’s a great way to add an extra dimension to your workout. It’s not all about bulking up it can also help with losing weight and boosting your metabolism.
Keen to track my new found weight training workout I looked at my fitness tracker and noticed it had a weight option. Turns out that this simply allowed me to set a goal where I could simply track time or calories. I was after something a little more advanced where I could track my reps and weights lifted which got me thinking is there a fitness tracker that is suitable for weightlifting.
We’ve taken a look at fitness trackers that are currently on the market to see which is the best when you are doing functional training, crossfit or weight lifting.
There are really 2 different routes to take when looking at the features you need to look for in a fitness tracker for weightlifting.
1. Tracking the weightlifting exercises
If you’re fed up of carrying around your pen an paper you will want to look for trackers that come with at least some of the following features:
automatic counting of number of reps
tracking of weight lifted
ability to create custom routines
ability to learn exercises
2. Tracking your heart rate and calories burnt
Alernatively, you might not be interested in tracking information about the weights specifically but more how much of an impact your weight training had on your overall session. For this you would look for some of the following features:-
Real-time Heart Rate Monitoring and calorie tracking
Ability to pair with a chest strap heart rate monitor
Compatibility with weight training apps on the tracker itself
Fitness tracker manufacturers have found the tracking of weightlifting a hard nut to crack. There have been a few attempts at trying to automatically track weights with devices such as the Atlas Wearables WristBand, Push Armband and GymWatch but the reviews are mixed about their ability to do it accurately.
It seems at the moment that the ability to accurately and consistently identify a rep is not quite there.
Advances in machine learning and big data helping the trackers identify the exercises from a large data set probably mean we are not too far away. Atlas are in the process of developing a new tracker the Atlas Multi Trainer which is the next iteration in this direction.
Aside from reps another potentially useful metric to track during your weights session is heart rate.
Most modern day fitness trackers use wrist based optical heart rate monitors. The nature of the exercises you do during a weights session it is all too easy for the watch to move around your wrist and lose the heart rate tracking – which somewhat negates its effectiveness.
In this case, you are best pairing your ANT+ compatible fitness tracker such as a Garmin Vivosmart 3 with a chest strap heart rate monitor which will give you both a reliable heart rate source and more accurate reading of calories burnt during your workout.
Weightlifting specific fitness trackers that attach to the barbell
In the area of strength and conditioning there has also been a lot of research into velocity based training. Indeed, some fitness tracker manufacturers have created fitness trackers that attach directly to the barbell such as the Bar Sensei (video below) and Gymaware
Fitness trackers that track weightlifting
Garmin Vivosmart 3
In the area of normal fitness trackers we think that the Garmin Vivosmart 3 is the best out there currently. As in the video below it has the ability to track reps on the watch, however as previously mentioned this can be hit or miss.
Fitness trackers with weightlifting apps
Samsung Galaxy / WearOS watches and GymRun
GymRun is predominantly a mobile phone app which allows you to track your weightlifting workouts.
Companion Version requires you to have a constant bluetooth connection to your smartphone.
Standalone Version doesn’t need your phone during the workout and allows you to sync your data from / to your watch before and after your workout. This version does come at a price. It is around $14 to buy the optional extra feature package.
With GymRun you will be able to create your own routine and input the weight and reps you are going for. This will then transfer to your phone with a rest timer to help you recover appropriately between sets.
Once you start your workout you can enter the number or reps and weight completed directly on your watch with a summary of your workout shown after you finish.
Best fitness tracker for weightlifting
We tried to be as exhaustive as possible in putting this together but if you know of one that is great at tracking your weights sessions drop us a line and we will look to include it.
small size measuring 5.5 – 7.1 inches (140 mm – 18 mm) in circumference
large size measuring between 7.1 – 8.7 inches in circumference

Fitbit Versa 2 Design
Continuing with the familiar and simple design that makes it look like an Apple watch the Versa 2 has some subtle and incremental design differences when compared to its predecessor.
Whilst, it won’t win any awards for innovation the design is practical, fits comfortably on your wrist and gets the job done.
The main watch unit is square in shape with curves in each of the 4 corners with the display centred within.
On the left hand side one single physical button can be assigned to a short cut with the majority of functionality accessed via the device’s touch screen.
The straps are made from the typical silicone material. They look like they would suit both large and small wrists. Indeed, the large band has 11 holes and the small one 12 holes which should give most people options. If you don’t like the ones that come out of the box there are lots of alternative designs available on Amazon.
As well as the standard black the Versa 2 also comes in a number of other color schemes included Copper Rose, Mist Grey and colors that are exclusively available via Fitbit.com.
Versa 2 has the capability to set up to 8 silent vibrating alarms directly within the tracker. You can customize both the level of vibration between normal or strong and the alarms themselves which can either be every day or for specifically selected days.
I’ve found that the normal settings wake me up easily and I usually set alarms at different times for the working week and non working days.
A notable new feature is also Smart Wake. The purpose of Smart Wake is to wake you up at the best point in your sleep cycle in the 30 minutes before your alarm is due to go off.
So for example, if you set your alarm for 6am and you enable the Smart Wake feature the vibrating alarm will start at any point between 530am and 6am.
To get the best out of this feature you need to ensure that your Fitbit has been regularly tracking your sleep. On a personal level, I tend to rise early naturally so when it start waking me another 30 minutes before I’ve found it strange. However, I think for other people it will be a really useful feature
Battery life & charging
The Versa 2 has a number of features that can significantly impact battery life such as always on display and music integration. If you don’t bother with these too much for typical usage the battery life is around 5 days,
Long battery life is definitely one of the Versa 2’s most appealing features.
Charging is simple too. Using the USB charger provided in the box simply pinch the sides of the cradle and line the pins on the back of the tracking device within the pins in the charger.
I’ve charged it from the mains, my computer and a portable battery pack and it typically takes around 2 hours to get to 100% charge.
Design wise the cable goes into the bottom of the charging cradle which means that counter intuitively you will need to rest the cradle on its side.
The display is a touch screen Color AMOLED which presents deeper colours to the eye.
If you don’t like the factory provided watch faces you can change to custom watch faces within the Fitbit app. So for example, if you are a healthcare professional you might want to download a face that displays a seconds hand.
With the latest update to Fitbit OS this functionality has been slightly enhanced. You can download 5 custom faces to the tracker which can then be switched using the Clocks app.
A quick settings page is accessed by swiping down from the top of the screen gives easy access to screen based configuration options
Always on Display (On or Off)
if On you will not need to press a button of flick your wrist to see the time. Does have an affect on the battery life
Brightness (Normal, Max, Dim)
Screen Wake (Auto(Motion), Manual(Button) –
in Auto mode the screen stays lit for around 10 seconds
If you want to track your run or bike ride you will need to take your phone along and use the connected GPS functionality.
Workout options like Bike and Run have a setting where you can turn On or Off Connected GPS. If it is on, the Versa 2 will try to connect to the GPS on your phone.
As soon as the connection is established the display will give you information such as pace and distance. After your run or ride is complete you can then view a map of your route by viewing that particular activity in the Fitbit app.
Heart rate monitoring and sleep tracking
Fitbit’s sleep tracking has a very good reputation, Whilst the majority of the insight is available within the app you are able to view the key indicators through the Today screen on the device itself.
As well as your previous night’s sleep, time in each stage and average sleep for the week you can view your Sleep Score. Fitbit say sleep score uses the data from your device and gives an indicator of your overall sleep quality.
Whilst we are on the subject of sleep the Fitbit Versa 2 now has a Sleep Mode. This can either be turned on manually or via a schedule which is configured on the watch
When it’s on the following will happen:-
notifications won’t cause watch to vibrate or screen to come on
screen’s brightness is set to dim
always on display clock face is turned off
turning your wrist won’t cause the watch to turn on
a sleep mode icon will appear at the top of the screen when viewing your stats
The Versa 2 has a 24/7 heart rate tracking functionality which samples at either 1 second or 5 second intervals dependent on what activity you’re doing.
Two interesting stats the Versa 2 offers from a heart rate perspective are:
During an activity where your heart rate is relative to hear rate zones recommended by the American Heart Association.
A cardio score that compares you to your peer group
The Fitbit Versa 2 like a lot of fitness trackers that play music has the ability to either store music on the device, stream it from a subscription service or control music apps playing on your mobile phone.
If you’re looking to go out for a run without your phone you will need to download the music to your Versa 2 using the Fitbit app on your computer and connect a set of bluetooth headphones so that you can hear your music. It’s a fiddly process but it does work.
Alternatively, you can pair your Versa via Bluetooth and control the playback by using the Music icon which appears if you swipe down from the top of the screen. You can play, pause, rewind and fast forward this way. So a great way to control apps like Google Music and Podcast Addict.
Finally, the Versa 2 comes with a Spotify app which allows you to remote control Spotify on your phone or computer.
Spotify app only works if you have a Spotify premium subscription
Smartphone notifications is a feature that allows your Fitbit Versa 2 to alert you on screen and by vibrating when there is any activity in the apps you have configured in the Fitbit App.
If you receive a call the number or name will display on the screen and you will be able to either accept or reject it. It is important to note that you won’t be able to take to call on the Versa 2 itself and you will still need to speak on the phone itself.
Within the Fitibt app, you can also choose which apps send you notifications and these will appear as snippets on the screen. So you might to receive e-mails, WhatsApp messages and notifications from your banking app
For Android phones it is also possible to reply to messages using the quick reply functionality. The type of quick reply can also be customised for each app from which you receive notifications.
Unfortunately, sometimes on my Android phone the connectivity can disappear which is one of the most frustrating aspects of the Versa 2
Alexa integration is a new feature offered by the Versa 2. To make it work you won’t need to have any existing Alexa devices or subscriptions but you will need to have an Amazon account and your phone nearby as it uses your phone to connect to the cloud.
Also, bear in mind that you will not have access to the same level of functionality as the Echo devices and the afore mentioned connectivity issues can cause problems.
As opposed to the Echo devices the Versa 2’s Alexa isn’t listening all the time. It needs to be activated by pressing the app in the watch or if you have set up the short by pressing left button on the device. The screen will then indicate that Alexa is ready for your query.
You can ask it questions like
whats the weather like in New York?
Set a reminder to go for a walk at 1145
Because the Versa 2 does not have a speaker the answers to your questions you will not hear a voice all responses are displayed on the screen
minimal set of smart watch features like smartphone notifications
You shouldn’t buy it if you are looking for more advanced features such as ECG, fall detection, the ability to make calls from your device. Those features belong to smartwatches like the Apple Watch or Samsung Galaxy watch
The Willful SW352 fitness tracker is a good option for the price. With an IP68 waterproof rating, long battery life and smartphone notifications it competes functionality wise with more expensive trackers. Given its price point it would be ideal as a first fitness tracker or as a gift for children.
Design wise the Willful Fitness Tracker SW352 goes for a slimline, narrow rectangular look. This means that it wouldn’t look out of place on your wrist at work.
Available in 6 colors and there is a single button to control the functionality. that wouldn’t look out of a place on your wrist at work.
The straps are interchangeable and extend from 5.5 to 8.3 inches by 0.59 inches wide so should suit most shapes and sizes of wrist.
To get the most out of the Willful tracker you will need to downloafd the VeryFitPro app which is available within the respective app stores.
Because the device itself is relatively simple, the app is where you control settings, phone notiications, alarms, historic data and time settings.
Like a lot of fitness tracker apps you need to sync to it daily before midnight then you will be able to see your workouts especially as the device itself resets at midnight
You can set up to 10 alarms in the app which then cause vibrating alerts on the tracker itself.
Can you use it without a smartphone?
In theory, you can use the SW352 without a smartphone but you would be limiting yourself to the very basic functionality that is on the device such as counting steps.
You would also lose the ability to track trends in the app as the device resets at midnight every day.
When it works it measure steps taken and the program coverts it to miles. It does not ask you stride length so it is all approximate distance.
this watch counts steps are implemented through a 3D gravity sensor, it will record some steps when you move your hands, so it may have some tolerance errors when you are using, but you can walk 100 steps to test if it is accurate or no
The battery life weights in at around 4 to 7 days for normal usage.
The Willful SW352 makes use of a standard USB charger which is extremely convenient. No more hunting around for the charging unit that you can never find.
To charge the watch you will need to :
separate the main body by pulling on the strap to expose the metal pins that plug into your USB port
clean the pins to ensure good contact and plug into your USB port
give it 2 to 3 hours and your device should be fully charged
The display is a 0.96″ OLED Color Screen which generally gets the job done.
However, some users report a couple of issues they have with the screen:-
hard to see in bright sunlight
tapping the screen to display the time can be a bit hit and miss
screen only lights up for about 5-10 seconds which can be too quick to see
Heart rate monitoring & sleep tracking
The Willful SW352 has sleep tracking and built in heart rate monitoring. It is fair to say that the implementations are slightly more limited than those on more expensive trackers.
The heart rate sensor is not continuous and takes intermittent samples throughout the day. There is no onboard display of heart rate so any details require you to go into the VeryFitPro app which is where you can also set details like maximum heart rate.
As with most trackers the Willful measures your sleep by interpreting the lack of movement of your body or wrist. It is quite limited by the fact that it only records the data between 9pm and 8am and only for periods of 4 hours or more. Again, to get the most from it you have to connect to the VeryFitPro app and ensure that all your personal information is complete.
Although not really a fitness tracking must have one of the best features of the Willful SW352 is the ability to integrate with your phone for notifications and remotely controlling your phone’s camera.
The VeryFitPro app allows you to choose which apps send you notifications and sends it to your wrist. It’s a really useful feature and does have its uses. However, the size of the display does mean that the text can be quite small
The good news is that the SW355 is IP68 rated so you can take it with you into the pool or the shower.
The bad news is that there is no swimming specific functionality so you can only real track your heart rate and activity when doing your lenghts.
The other issue that is common with a lot of touch screen trackers is that sometimes the water from the shower can inadvertently kick off an activity. Not the end of the world but a little bugbear.
You’ve never owned a fitness tracker before and want to get insight into your daily activity and whether a fitness tracker is for you
Want a cheaper alternative to Fitbit if you’re kids are pestering you for a tracker this is a great inexpensive choice which offers a lot of similar functionality to a Fitbit at a fraction of the price
You’re fed up of trying to find your charging cable – the ability to plug this directly into the USB port is a great advantage
You need a fitness tracker if you really want to improve your health. When I first started wearing fitness tracker a couple of months ago, it was frustrating to try.
But when I started wearing it I came to know about its health benefits. I got to see all my statistics right on my wrist. Charting my over time it was like something from a superhero movie,
I was like wow this thing can really help in improving health.
I recommend fitness tracker because it can boost your daily workouts and make it part of your daily routine to achieve targets. It is important to mention that an easy to use tracker is actually motivating towards achieving your health and fitness goals.
Most fitness trackers have more functions than a Swiss Army knife. Usually including a heart rate monitor, distance trackers, exercise programs, calorie trackers and many more, all with the intention of improving your health. If you feel a significant improvement in health, you will never stop using it.
Buy or dust off your tracker
Have you been thinking about buying a fitness tracker, or do you have one, and its collecting dust?
Well now is the time to either buy that tracker or dust it off. Because here you will get answers to the questions which are clicking in your mind. Like, do fitness trackers really improve health? Do fitness trackers motivate you? Fitness trackers have the potential to be one of the best tools which can improve your health and also motivate you.
To find out detailed answers to the aforementioned questions, first, you need to know precisely about fitness trackers.
Do fitness trackers work and really improve health?
Before we get into it, do fitness trackers work and really improve health? To put it into simpler terms, fitness trackers measure movement and motion. They use sensors that can track the following things:
They collect data and immediately convert it into steps, calories, sleep quality and general activity that you do all over the day. There is also a sensor called the ‘altimeter’ that can measure your altitude. It must be noteworthy that, the more sensors your fitness tracker has, the more accurate it can be for you.
Now moving towards the question; do fitness trackers work and really improve health?
Yes, if used.
My guess is that most people take it for granted that fitness trackers are helpful in improving your health, but that’s based mostly on hypothesis.
So, what did they find?
Fitness trackers on their own won’t improve your health; that’s true. But what trackers can do is motivate you, hold you accountable, and measure metrics that you normally wouldn’t think to look at when it comes to your overall fitness. If you’re thinking of slapping a fitness tracker on your arm but need a little more convincing, then read ahead.
The fundamental hypothesis driving the smartwatch industry is that losing weight is a simple matter of “calories in versus calories out”. This view is held by many fitness experts, bodybuilders, and nutritionists. But not all.
Alternative crowd maintains that counting calories are actually unproductive for a large number of the population. According to this viewpoint, the answer has more to do with metabolism, insulin sensitivity, hormone balance, gut bacteria, nutrient density and so on. This group of people might answer the question of whether fitness trackers really work quite differently or not.
Allow me to be so bold as to present my point of view.
Burning more calories than you consume will affect weight loss.
Smartwatches and the calorie counting people rely on a number called an Active Metabolic Rate to do their math. This is the number of calories that you burn during a normal day of work. In turn, this is calculated as your Basal Metabolic Rate the number of calories simply required for breathing and thinking plus any activity on top.
To get your BMR and therefore your AMR you have to enter these required inputs:
This is needed because taller people require more energy just to go about their usual business that’s why bigger folks tend to eat more. Similarly, men and women burn different amounts of calories. You can also do a BMR calculation using your lean body mass.
Two people roughly the same height and weight won’t burn the same number of calories. If you have a higher level of testosterone then you will burn more calories and build more muscle. Hormone balance plays a big role. Similarly, thyroid hormones, cortisol levels, insulin, and some other factors all play a role.
You don’t believe that hormones can make much difference to your physique? Look at somebody who uses steroids. They would have the same numbers as anyone else on a fitness tracker, but they’d look a lot different. On the other hand, many women who start using oral contraceptives can also gain or lose weight as a result.
Our guts harbor a lot of friendly bacteria that play a very vital role in our health and well-being. These bacteria help us to produce hormones and neurotransmitters; they aid with our digestion, and they fend off bad bacteria. Several case studies have shown us that fecal transplants can result in rapid weight loss or weight gain due to the loss or addition of the bacteria.
Millions of people use fitness trackers to monitor their health and fitness. If it were possible to count calories going in and out, this would lead to more precise predictions of weight gain or weight loss.
Not just for exercise junkies, the data from fitness trackers may help predict and even prevent heart disease, blood pressure, and count calories. Sensors on these devices track each and everything from body movements to heart rate and even blood pressure. They also include loud alarms to remind users to stay active throughout the day.
Despite mistakes when it comes to recording your activity, wearable trackers can be useful for improving your daily workout. Because the majority of adult’s exercise comes in the form of walking, your step count should provide a good approximate of your daily activity.
For many fitness-band wearers, the accurate number of steps jogged matters a lot. The bands can increase competition to outwalk friends and encourage them to take an evening walk. Those who wore fitness trackers significantly increased the time they spent doing moderate to energetic activity. These facts remove the doubt about do fitness trackers work and really improve health.
Do fitness trackers motivate you?
A fitness tracker can help by providing valuable data and collecting your health and fitness information that allows you to see what you’re achieving. It also records any improvement. These can all work together to keep you motivated.
People are more motivated to push themselves when they can visibly see their activity levels. It also helps them reach to their next fitness level. Seeing their progress can give them a feeling of achievement, which in turn increases motivation.
Being sufficiently motivated plays an essential role in whether people are able to increase and maintain their physical activity levels. But it must be kept in mind that not all forms of motivation are equally powerful.
There are three forms of motivations:
1. Autonomous Motivation
When a person does something freely, willingly and with a positive attitude, it usually indicates higher motivational quality which is known as autonomous motivation.
2. Controlled Motivation
If a person does an activity mainly in response to other’s demands or pressures such as rewards, competition or comparison with others, this is indicative of lower motivational quality which is known as controlled motivation.
When a person has no desire to take part in an activity at all, then this state is known as amotivation.
Greater motivation depends on three basic “needs”:
Autonomy: It is the need to feel a sense of ownership over your actions.
Competence: It is the need to feel adequately-challenged and experience a sense of accomplishment.
Relatedness: It is the need to feel connected to others and supported in your endeavors.
Both autonomous (higher) and controlling (lower) forms of motivation can prompt changes in our behavior, but autonomous motivation is more durable and beneficial in the longer term, particularly for physical activity and weight loss.
Goal-setting and self-monitoring of progress can maintain the development of high-quality (autonomous) motivation for physical activity. Fitness trackers are really helpful motivational tools to support people in making long-term lifestyle changes and becoming more active, both during and after taking part in a weight loss and healthy living plan.
Overall, fitness trackers can motivate increased performance and raise the effectiveness of the workout.
Benefits of Fitness Trackers
There are a number of benefits for people who want to increase access to health and activity trackers in the workplace. As a result, fitness trackers can really improve their health too. The top 12 benefits are:
1. An environment focused on health
For many years, work environments have made productivity and profit the top priorities, while health received little to no attention. The good news is that the arrival of fitness trackers, along with other wellness devices tied to specific outcomes, have moved health to the front position of the workplace environment. This, in turn, creates a stronger sense of companionship, happiness and overall employee retention.
2. Enhanced chronic disease management
Diabetes and high blood pressure are chronic diseases that require constant monitoring and management. Fitness trackers allow people to monitor their physical activity, what they are eating on a daily basis and many more. This can lead to improved health and, eventually, increased productivity due to a decreased rate of workplace absences related to illnesses and other disorders.
Wear your fitness tracker to bed, and perhaps your nights will be more restful and you’ll feel better in the morning. This can lead to improved health and, eventually, a decreased rate of workplace absences due to sleepless nights.
3. Up-to-date weight loss tool
As you’re busy trying to maintain your personal records, you may not even notice the gains or losses you’re making in your weight. Fitness trackers can make calorie counting more convenient than ever. They can also help you manage your food intake.
Many fitness tracker apps have nutritional information databases. So if you want to count your calories, no longer do you need to carry calorie book with you at the workplace. You set a daily calorie goal, you can see at a glance how many calories you have left in your budget and how many calories you’ve burned.
4. Get better at sports
Even if you’re fit then you can still benefit from using a fitness tracker. With the help of fitness trackers, you’re able to track metrics (such as speed, number of laps, and revolutions per minute) related to specific sports such as running and cycling etc. It helps you to see how well you’re performing and track your progress.
5. Counting steps is easy
It may sound unreasonable, wearing a fitness tracker for counting your steps. But it really motivates you to simply strive yourself to improve your daily steps goal. You can also see how many steps you walked per day and it motivates you to do better the next day. So it reduces your laziness and encourages you to go across the world.
This is a great feature for those who need a little push out of the door to get moving in the morning. Most fitness trackers work with third-party apps where you can challenge a friend to a workout and post your planned sessions to keep yourself accountable to your exercise program. Social exercise aids in helping us perform more regular exercise and avoid pulling the cover over our heads to sleep in. Additionally, when you do get in that activity, you can share it on social media with your active friends.
7. Motivate healthy habits
The intensifying use of smartphone apps with built-in motivations has turned health monitoring into a game. In fact, both small and large companies have taken over games and expanded it further by putting programs in place that motivate healthy employee habits.
8. Pushes you to achieve your goals
Goal setting is the significant feature of fitness trackers and it lets you set the goal and keeps you engaged in your goal progress. In an increasingly deskbound society, fitness trackers are one way of giving you an extra push to get you out of your seat. They are motivating people to reach their health goals i.e., self-monitoring, setting goals, getting feedback on their progress, revising goals, social support, and developing a sense of self-efficacy.
9. Keep track of your progress
A good fitness tracker will have the option to track your progress, calories, steps, distance and heart rate monitor. Moreover, you could summarize your last week or months’ achievements. As well as, it will shake and inform you when your goals will be achieved, i.e. 6000 steps or 20km. It feels good to see your progress and how much stronger you have become.
10. Personal accountability
Fitness trackers track your goals and your progress, psychologically encouraging you to walk more steps than you did yesterday; to run faster than you did yesterday; to sustain peak heart rate for just a little longer. Wearing a fitness tracker can increase a user’s activity levels. Eventually, a decreased rate of workplace absences due to bad health.
11. Incentives promote activity
Fitness is not an individual hobby or habit. Workplaces are getting involved in encouraging employees to adopt and maintain a healthy lifestyle with many incentives. Having a healthier member of staff cuts down costs for companies too.
12. Tracks even while you sleep
Sleep is linked to the quality of your health and lifestyle. Fitness trackers can easily determine the quality of your sleep on the basis of your movement during sleep. Most fitness trackers have built-in sleep monitors, which measure how long you sleep and estimate the quality of your rest by how much you move around while you sleep.
Finally, it is concluded that fitness trackers continue to play an important role to improve your health and also motivate you. The focus of these devices has been on individuals interested in working towards specific health and fitness goals. I’ve been a user of fitness trackers for years. So, I enjoy tracking my daily activity, exercise and more with my own fitness tracker.
The ability to link your fitness tracker with others, even if they don’t have the same tracker as you, is an innovative way to connect with others. Moreover, you may connect various devices and track your health and fitness data from numerous data sources. This information will be precious for your future safety.
So, if you have a fitness tracker lying nearby, or you have been thinking of getting one, now is the time to make use of it. Gather some close, or not so close friends for motivation, challenge, and fun. Spread the word, “the more the merrier”.
The Fitbit Versa range fits neatly into the category of fitness smartwatches. By taking some of the features of smartwatches such as notifications and combining them with their fitness tracking guile Fitbit hoped to provide an affordable alternative to devices like the Apple Watch.
The original Fitbit Versa did this with great commercial success. So much so, Fitbit have launched a successor the Fitbit Versa 2.
So between the Versa and Versa 2 which one is best?
Should you upgrade if you own the Fitbit Versa?
Take a look below as we pit them head to head in a showdown to help you decide
Alexa integration: The Versa 2 allows you to its Alexa integration to perform functions on your watch such as setting the alarm
Display: The Versa 2 comes with an AMOLED display which is much brighter than the LCD version on the Vera.
Always on display: The Versa 2 has the ability to set the screen so that it is always on – does affect battery life
Battery life: The Versa 2 in normal use which is around 1 day more than the Versa
Price: Fitbit are pricing the Versa 2 so that in most cases it is the same price as the original Versa
From a distance you would be hard pressed to spot differences between the Fitbit Versa and Fitbit Versa 2. The Fitbit Versa 2 has a slightly larger screen and aesthetically its styling makes more use of curves. Overall, the design of both is still very similar to the Apple Watch.
For physical controls the Fitbit Versa 2 has dispensed with the 2 buttons on the right of the Versa leaving one button on the left hand side which can be linked to a shortcut.
The Fitbit Versa 2 also has the same mechanism for changing straps as the Versa. Definitely no improvements here. It’s still very frustrating to change a strap.
Fitbit Versa 2
1.56″ / 3.98 cm
1.56″ / 3.98 cm
0.47″ / 1.19 cm
1.55″ / 3.93cm
1.55″ / 3.93 cm
0.45″ / 1.14 cm
The Versa 2 did away with the Fitbit logo from the Versa resulting in a little bit more screen estate, the device is also ever so slightly deeper. On the wrist it does feel slightly bigger but not to point where you will notice a massive difference.
Fitbit Versa 2 vs Fitbit Versa Showdown
When comparing Versas we use a range of common fitness tracking features. In each category 1 point is assigned to the outright winner and 0 to the loser. In the case of a tie we give 1 point to both devices. The Versa with the most points is the winner of the showdown. The features we use include:-
Fitness Tracking Features
Heart Rate Monitoring
The Versa 2 manages to extend the Versa’s already impressive battery life from around 4 days to just over 5 days for normal usage.
For upgraders, it is a bit frustrating that the previous charging dock can’t be used
Fitbit Versa 2
The Fitbit Versa has a 1.34 inch color LCD touch screen with 300 x 300 pixel resolution which towards other devices on the marker can look a bit dated
The Fitbit Versa 2 keeps the 300 x 300 resolution but is now an AMOLED touch screen
When comparing side by side the Versa 2’s screen is much brighter and the colors have a lot more depth with a much better contrast.
Another feature added to the Versa 2 is an Always on Display a great boon and with the latest Fitbit OS there are a number of clock faces that are Always On.
Fitbit Versa 2
Fitbit have decided to stick with the same connected GPS capability.
Does that mean I have to take my phone to track my run?
Yes, as neither Versa has an onboard GPS chip the only way to track a GPS run is by connecting your Versa to your phone and taking your phone along with you.
Fitbit Versa 2
Heart Rate Monitoring
This is a tie as both devices come with the same heart rate sensor which operates 24/7 and continuously collects data points to enable Fitbit to calculate a cardio score.
Fitbit Versa 2
Both devices have the ability to store music on-board which can be listened to using bluetooth headphones. The Versa 2 comes with a Spotify app pre-installed which is not currently available on the Versa.
It is important to note that it is not possible to do sync your Spotify songs to your Versa 2. The Spotify app is available for Spotify Premium subscribers and acts like a remote control where you can use your watch to control your Spotify connected device.
Fitbit Versa 2
Sleep tracking is always been well regarded on Fitbit devices. The Fitbit Versa 2 takes this a bit further by providing a metric known as your Sleep Score to give you an insight to your overall sleep quality
Fitbit Versa 2
Both devices have water resistance to 50 metres and can be used in the pool. Although neither device has any swim tracking functionality and simply record your active time.
Overall, we think there is no compelling reason to upgrade if you are happy with your current Vera. A lot of the functionality is Fitbit OS specific and will probably filter down to the Versa in time. You need to make the decision based on whether some of the new functionality such as Always on Display, Alexa integration and quick replies on Android are important enough for you to spend the cash and take the leap.
Should I buy the Fitbit Versa or the Fitbit Versa 2?
If it comes down to a decision between the Versa and Versa 2 you need to decide whether the newer features on the Versa 2 are important to you.
If you can live without them both watches share a lot of similar functionality – why not save yourself some cash and go with the Versa.
On the other hand, if you want to benefit from the brighter AMOLED screen, alway on display functionality and Alexa integration Fitbit are pricing the Versa 2 very competitively against the older model.

There are a lot of fitness trackers on the market and a lot of different features for each one, so it can be difficult to make an educated decision about which one to make. However if you are looking for a fitness tracker that also measures blood pressure, you’ll be able to narrow your field significantly. The technology for measuring blood pressure is still fairly new, so there are not many trackers with this feature.
That begs the question: Are there enough viable choices for fitness trackers? Check out this list of some of the best fitness trackers with blood pressure to find out which one will work for you.
Omron has been a big name in blood pressure monitoring for several years, so the name alone comes with a lot of clout. Being a big name in blood pressure, it was important that their smartwatch was cleared by the FDA as an accurate monitor before it hit the market, which it was.
This fitness tracker does not employ the commonly used PPG technology that is found in all other fitness trackers that claim to monitor blood pressure, but instead has an inflatable cuff that is supposed to be more accurate.
Though the inflatable cuff is more accurate, it isn’t exactly convenient. No one likes to be interrupted during their day to have their blood circulation cut off. You can make the settings whatever you want, but if you don’t like the feel of the inflatable cuff to get your blood pressure, this might not be an option for you.
The design is a good one, and squeezing an inflatable cuff into a smartwatch is a challenge, but it does remain that it is more bulky than most smartwatches. If you are someone who has a heart condition however, this design is much more sleek than the typical wrist worn wireless blood pressure monitors.
The Asus VivoWatch BP is a fairly new model of fitness tracker with a more accurate blood pressure monitor than most. It has two sensors, one for ECG and one to read your PPG through your finger. With a combination of the two readings, you can get a more accurate read than some of the other fitness trackers that list blood pressure monitoring among their features.
Compared to the bulky Omron Heartguide, this smartwatch is light as a feather and has a sleek design that won’t get in your way as you go about your daily activities.
If you record your blood pressure a few times a day, you can send it to your physician and he or she can have a more accurate idea of your blood pressure condition throughout the day.
The watch takes two hands to get a reading, which isn’t necessarily a bad thing, but it is more “hands on” than other fitness trackers.
This smartwatch also doesn’t offer many more features than the basic step counter, heart rate monitor, sleep tracker etc. It isn’t really a watch that you would use to scroll through apps and really personalize your health goals. However, if you just want to have basic health tracking features, then this is a great option without getting too technical.
The MorePro is another affordable option for a fitness tracker, especially with a blood pressure feature. It is lightweight and has a comfortable design. There are not too many screens to scroll through and it is very simple for even the least tech savvy user.
This uses PPG technology on the wrist and it records at a higher blood pressure than what is typically recorded from the upper arm. This is a good option for the price and can be useful to track trends in your blood pressure, but again, it isn’t medically graded accurate.
The Fitfort fitness tracker comes at a very affordable price and has all the features you would want in a fitness tracker. It doesn’t have smart social apps, but it has all the other basic fitness features.
The Fitfort uses PPG like most of the other fitness trackers on this list, and has the common problems that come with it. It typically records blood pressure higher than that person normally would. This is a problem with PPG technology and the location of the wrist. It might not be a big deal to some, but if you are buying the tracker for the purpose of recording an accurate blood pressure reading, you may want to check its accuracy against blood pressure monitors.
Many people say that a fitness tracker is only as good as its app, and the app that comes with this tracker is simple to use and helpful. The Bolzun Fitness Tracker B15P is reviewed to be about on par with the other fitness trackers that measure blood pressure through PPG technology. However, many reviewers have found that the blood pressure monitoring becomes more accurate over time. The more you use it, the better calibrated it is to your body.
The app is also simple to use and easy to navigate, though your blood pressure will not automatically show up in the app each time you use it.
Everything else that the tracker records shows up automatically, namely the step counter and calorie calculator, but the blood pressure requires that you press a button in the app for it to record the information each time you take your pressure.
This may be one of the most affordable fitness trackers on the market, let alone blood pressure specific fitness trackers. It works well with an app and you can customize the screen to have specific notifications. The battery life lasts a long time and provides continuous heart rate and blood pressure monitoring.
Again, it is not medically graded for blood pressure. Especially when fitness trackers are continuously recording blood pressure data–rather than periodically–the data can be incorrect. The blood pressure monitors that have the most accurate readings are the ones that require that you sit still for about a minute with your wrist and heart height. PPG can be sensitive to movement, so the blood pressure reading in this particular fitness tracker is probably off by a bit.
Again, another affordable fitness tracker option. The app and fitness tracker are easy to use and have a simple design. The pedometer is accurate without GPS.
As with many of the above mentioned trackers, it uses PPG and has a higher than normal blood pressure rate when used. Again, this is an issue with the technology available currently and the location of the fitness tracker on the body.
The design can also be a bit fragile. The straps pull off of a USB plug for charging and some users have complained that it breaks if you’re not careful pulling the strap off.
External Blood Pressure Monitors
As mentioned earlier, blood pressure monitoring is fairly new to the fitness tracker market. Tracking blood pressure is an important tool that would benefit every person at every fitness level, however it remains to be in its beginning stages of continuous measurement.
If you have a serious heart condition, consult your physician about what options would be best for you to monitor your blood pressure. Perhaps one of these on this list will be sufficient, but if you have a very serious condition, you will probably want to go for something approved by the FDA.
More information is always better than less, so if you have a fitness tracker using PPG that you have found to be fairly accurate, it can’t hurt to use that continuously to track your blood pressure while regularly checking in with an external blood pressure monitor. If you would like a list of some external monitors that are compatible with your phone, check out the end of our article titled “Can Fitness Trackers Measure Blood Pressure?”
Though there are very few medically graded options for a blood pressure monitor available today, there are high hopes for technology to develop in the near future. The big names in fitness tracking such as Garmin, Fitbit, and Apple, as yet have not put out a reliable blood pressure monitor, likely because they are working on the highest quality technology to make a big splash when they release it. This is definitely a feature to keep your eye out for in the coming years.
Measuring blood pressure through a fitness tracker is a relatively new feature that tracker companies are just starting to develop. Though there may not be many options for blood pressure monitoring trackers, there are some on the market, and they are getting more and more accurate.
So how do fitness trackers measure blood pressure? There are three main methods to finding out your blood pressure through fitness trackers. The most accurate is through traditional cuff inflation, with photoplethysmography (PPG) at a close second, or, a little less conveniently, from external devices. Read on for more information about each method.
Currently, there is one smartwatch fitness tracker on the market that uses an inflatable cuff at the wrist to measure blood pressure and that is the Omron Heartguide. You can find out a little more about the Heartguide here.
Many argue that measuring blood pressure using the cuff method is the most accurate way to do it. This claim is substantiated by the FDA, since the Omron Heartguide is the only smartwatch approved to check blood pressure, though other smartwatches and fitness trackers have blood pressure tracking listed among their features.
However, just because Omron is the only one approved to check blood pressure accurately, doesn’t mean that some of the other fitness trackers aren’t accurate if used correctly. The technology for photoplethysmography PPG is still fairly new; if you don’t have a heart condition, you may want to compare one of the PPG trackers against a blood pressure monitor to check accuracy.
If you do have a heart condition, then the best route to take would be to ask your physician for advice, or bring your tracker in to the doctors office to compare it with your physician’s reading.
The technology that is used in most fitness trackers that claim to read blood pressure is photoplethysmography or PPG. This process is technical but simply put, the device emits a light and measures the reflection of this light to, in turn, measure the blood volume. According to the National Center of Biotechnology Information, the device will emit an infrared light to measure the blood flow deep in the tissue or muscles. If the device emits a green light, it is commonly measuring the absorption of oxygen in the blood (NCBI).
This is the technology that is used in finger cuffs that you may have used at the doctors office. It does an alright job, but it is not accurate enough for most doctors to use say, during a surgery.
This is also the technology that is used in many fitness trackers that claim that they record blood pressure. It is not technically blood pressure, but the measurements are correlated enough to replace a blood pressure measurement.
If you aren’t the type of person who wants to have a wrist cuff inflating on you several times in a day, but you do want to have the most accurate blood pressure readings possible, then an external blood pressure device might be just what the doctor ordered–literally.
There are several blood pressure monitors on the market currently that will pair with your phone or smartwatch either with a cord or through bluetooth, making sure that all your information is in the right place.
The wrist is arguably not the best place for measuring blood pressure. The arteries are very small and the bones can also get in the way of the most accurate reading. This is why most doctors prefer to take your blood pressure on your upper arm where the arteries are thicker and a cuff can apply more pressure.
So if you are planning on tracking your blood pressure because you have a mild curiosity about how your fitness level is affecting it, you’ll probably be just fine with the PPG method of measuring blood pressure. If, however, you have a heart condition already, you may want to invest in one of the external devices, or even do both to measure the accuracy against each other.
Why Is Ambulatory Blood Pressure Beneficial?
Your blood pressure is arguably the most important aspect of your health to monitor. This is because it is a preliminary symptom of hardening of the arteries, stroke, kidney disease, or heart attack.
The American Heart Association states that “High blood pressure is a largely symptomless ‘silent killer.’ If you ignore your blood pressure because you think a certain symptom or sign will alert you to the problem, you are taking a dangerous chance with your life” (AMA).
Office Monitoring Is Not Enough
Many people who have “white coat hypertension” or get overly nervous at doctors appointments resulting in high blood pressure, are recommended to use ambulatory blood pressure monitoring. This is a portable blood pressure cuff that the patient can wear throughout his or her daily activities to give his or her physician a 24 hour period of time of regular monitoring.
The measurement that a doctor gets in the office is meant to be a resting blood pressure, and whether you get nervous around doctors or you simply had to rush to get to your appointment, your blood pressure could be much higher than what your daily average might be.
This is why ambulatory blood pressure monitoring is the preferred method of getting an accurate reading of blood pressure if your doctor is determining to diagnose you with hypertension. An average of your blood pressure readings throughout the day, including periods of exercise and sleep, is the most accurate way to measure your blood pressure and your overall health.
With heart disease the leading worldwide cause of death, and high blood pressure the leading indicator of heart disease, blood pressure is more important than ever to monitor. Therefore, having a blood pressure monitor on your fitness tracker should be an important feature that you look for.
Why Are There Not More BP Fitness Trackers?
If you search for fitness trackers that measure blood pressure, you don’t come up with too many immediate results.
Why is this? One of the primary reasons why there aren’t very many trackers that measure blood pressure, in the US at least, is since fitness trackers deal with your health, they have to pass certain FDA approved regulations. There are some on the market that have been deemed acceptable, but not recommended.
Though the wrist is currently not an ideal place to measure blood pressure, and you will get a more accurate reading on your upper arm, technology is only getting better with time, and there may be a day in the very near future where blood pressure monitoring from the wrist in fitness trackers is commonplace.
Many people want to measure their blood pressure regularly, if not continuously, but very few people want to deal with the inconvenience of having an inflatable cuff on their wrist cutting off their blood flow every 15 to 30 minutes. Even with the Omron Heartguide, you do have to stop what you’re doing and hold your wrist at heart level to get an accurate reading.
Right now, a fitness tracker with an inflatable cuff, is a good idea, but still impractical for frequent everyday use. This is why scientists are working on a new technology that doesn’t require an inflatable cuff or an infrared light to get a blood pressure measurement. According to the National Institute of Standards and Technology US Department of Commerce (NIST), cuffless accurate blood pressure monitors may not be far off.
The NIST explains that scientists are working on a blood pressure monitor, that instead of inflating, will “gauge subtle pressure changes at the surface of your skin above one of the main wrist arteries – the radial artery – without regularly cutting off your circulation” (NIST).
The challenge with this method of measuring blood pressure, other than it has never been done before, is that the scientists have to create a model that mimics arteries in the wrist to test it, which they have done using a 3D printer.
They use a silicone pad to mimic the tissue of an arm and have a fake artery running through it. Then they use sensors to record data as different weights are pulsed against the silicone. In this controlled environment, they can see how accurate their measurements are and what kinds of readings the sensors are picking up. This technology still has some work to go, but could be ready for a prototype in the near future.
The technology for measuring blood pressure is advanced as it stands now, but still flawed. There is definitely room to grow and, in an overly saturated market of fitness trackers, it will be interesting to see which companies pursue developing this technology to stand out from the crowd. Blood pressure is a vital part of overall health and the technology to monitor it accurately will prove to be worth the effort of developing.
Blood pressure is a big component of your health, which is why it is the first thing doctors will check each time you come in for a physical. It is something that most people rarely think about day to day, but is a great indicator of how healthy you are.
So maybe this is of interest if you’re a fitness junkie, or even just curious
Can fitness trackers measure blood pressure? Well, yes and no. There are quite a few fitness trackers on the market today that claim to monitor blood pressure, and in all honesty, most of them have decent reviews for accuracy, though they seem to record a bit high. However, currently there is only one that is officially approved by the FDA for blood pressure monitoring. You can read more about that here. Read on to find out all the information about measuring blood pressure through fitness trackers.
What Is Blood Pressure?
The term “blood pressure” sounds so much nicer than the measurement of blood pushing against the sides of your blood vessels, but that is essentially what it is. When you measure your blood pressure it is just telling you how much strain your heart is going through to pump the blood throughout your body.
What Is Your Target BP?
There are two parts to your blood pressure: systolic and diastolic. Systolic, the top number when reading blood pressure is always the highest as it is reading the amount the amount of pressure when your heart is pushing the blood. Diastolic is the bottom number and the lower number because it is reading when the heart is between beats.
A normal resting BP reading is about 120/80 or below. Many people won’t have that exact blood pressure, but that is the normal range. Typically, the lower the blood pressure, the healthier you are, but of course there are limitations to that. If you get lightheaded easily or faint, then that is a good indicator that your blood pressure is too low. This can happen if your blood volume is low due to an injury or shock. However, if you have extremely low blood pressure readings and no symptoms, then you may just have an inaccurate reading.
Most fitness trackers use PPG or photoplethysmography, which means that your fitness tracker will emit a light source into your wrist and measure the reflected light as it bounces back to gauge the blood volume in your wrist.
The FDA has not technically approved fitness trackers that use this method as an accurate blood pressure monitor, but many users have been surprised by how accurate they find their PPG trackers to be. It does tend to measure a bit higher than normal, so if you have a serious heart condition, you may want to ask your doctor what he or she recommends you use for a blood pressure monitor. Or you could use one of the external blood pressure monitors listed at the end of this post. Using your fitness tracker to monitor your blood pressure regularly while checking it occasionally with a cuff pressure monitor is also a great option.
How Accurate Are Wrist Blood Pressure Monitors?
If it is overly difficult for wrist fitness trackers to be approved by the FDA as a blood pressure monitor, then you can assume that they are difficult to make accurate. According to the Mayo Clinic, the wrist and fingers are challenging spots to get an accurate blood pressure reading because the the wrist arteries are narrower and not as deep under your skin as those of the upper arm” (Mayo Clinic).
They go on to explain that another reason why wrist blood pressure readings are difficult to get is because the fitness tracker should be held at heart level each time to get an accurate reading. It is also difficult to get an active reading since every kind of blood pressure monitoring method, whether by cuff or through PPG, is sensitive to movement.
Because blood pressure is difficult to measure at the wrist, many fitness trackers haven’t developed this feature to where it is working perfectly. However, all fitness experts recognize the importance of having a low blood pressure and that tracking your blood pressure throughout the day can be helpful to figure out how to get your health where you want it to be.
For this reason, some fitness trackers are equipped with app capabilities to connect to an external blood pressure monitoring device.
You may wonder why you would ever want to have an external device that connects to your phone, tablet, or watch rather than just to have a generic blood pressure monitor. There are a few reasons why connecting to your device is a feature you would want to look for.
It’s convenient to record the data.
All your fitness information will be stored in one place.
You can easily send this information to your physician for reference.
You can view trends and compare them against activity levels during your day.
Here are some of the blood pressure monitoring devices that are compatible with phones:
This is FDA approved and the reading is taken at the wrist, which is convenient. This cuff is compatible with both iOS and Android using the MOCACARE app.
Compatible with iOS and Android for use with phones, tablets, and smartwatches through Bluetooth and free app. This is medically accurate and very portable.
Omron Gold Blood Pressure Monitor
This wrist worn monitor is comfortable and easy to use, especially for people who experience discomfort with upper arm readings. This is compatible with iOS, Android, and Alexa enabled devices. It can be used to track blood pressure for two users and connects to devices through Bluetooth. One other helpful feature is position directing; it will tell you when your wrist is in the correct position at heart level. It also is discreet and completely silent when inflating.
OMRON 10 Series Wireless Upper Arm Blood Pressure Monitor
Like the Gold Blood Pressure Monitor, the Omron 10 series is wireless, for up to two users. It will take three consecutive readings and average them to get the most accurate reading possible.
Greater Goods Bluetooth Blood Pressure Monitor Cuff
This is an affordable option for a wireless blood pressure cuff that connects to your smartphone. A portion of all sales goes to charity as well.
Overall, measuring blood pressure is much more complicated than it sounds and putting it in a fitness tracker is a huge challenge to undertake. This will be the next big thing to look for in fitness trackers throughout the next few years, and whatever company figures out the technology to get the most accurate readings will likely have an edge over the market.
Before we start looking into the fitness tracker element of this post we want to say how much we appreciate the work that nurses do around the world.
Nursing is a rewarding and challenging career that comes with its fair share of highs and lows. The satisfaction that comes from helping others is tempered by the downsides. Often, you may face difficult situations involving patients, colleagues, emotions. Couple this with long hours, stress and extended periods of being on your feet that involve physical aspects of moving people and equipment.
What if you could monitor some of these aspects of your job with a fitness tracker? We’ve taken a look at the options currently out there to try and find the 3 best fitness trackers for nurses
Fitness trackers for nurses break into 2 different categories:-
Worn on the wrist where the tracker is similar to an old fashioned wrist watch. Price determines the features you get. Typically, as a minimum you get step tracking and calories burnt.
Clip on where the fitness tracker is worn either round the belt loop. These are useful if you have a policy such as in the UK where nothing should be worn below the elbow. Typically, these have a more restricted feature set.
Fitness trackers for nurses
For nurses, the following features will help you get the most out of your fitness tracker:-
Reasonable battery life to cope with long shifts
If wrist worn an always on display so that you can measure a patient’s vitals easily without needing to touch the watch if you have gloves on
A fitness tracker that is good for both your home life and your work life
Ability to measure metrics such as steps taken throughout shifts
1. Fitbit Versa 2
The successor to the highly successful Fitbit Versa. The Versa 2 builds on the solid foundations with some additional functionality. Key for nurses, will be the ability to configure an always on display. Although, this will require more frequent charging. If not using the always on display battery life is around 4-6 days. Other key features are a heart rate monitor, sleep tracking, 24/7 step tracking, waterproof, smart phone notifications and if you have an Android phone the ability to respond to messages via Alexa.
If you’re not concerned with owning the latest versions the original Versa is still an excellent value for money fitness tracker. It is a hybrid of smart watches and an activity tracker whilst still not being as expensive as an Apple Watch or as advanced as a Fitbit Ionic. Water resistant with features like a heart rate monitor and sleep tracking which you can monitor through the Fitbit app.
You can also customise it using custom watch faces available from the Fitbit App store such as this one called Medical Professional. It is specifically designed to make it easy for medical professionals to take vitals.
The Garmin Vivomove HR falls into what are know as hybrid smartwatches. The advantage is that the watch face looks like a traditional watch with a seconds hand. In reality, the watch face is actually a touch screen giving you access to more advanced features such as all day stress tracking, smart phone notifications and silent alarms. The watch face is a great idea but there are some reports that in certain light conditions it can be difficult to see.
The Fitbit Zip is small compact and limited in functionality towards some of the wrist worn trackers. However, if you need to comply with a bare below the elbows policy it is a good choice. The Zip fits in a silicone sleeve which you wear on your person typically over your belt loop.
Functionally, it is very simple with most of the data being available on the screen. Tapping on the screen will cycle between different stats including distance travelled, the time, steps taken and calories burnt (all between midnight to midnight). Due to its simplicity it uses a watch battery giving a battery life of 4-6 months. The downside of this is you miss out on a lot of features of the other trackers such as alarms, sleep tracking and heart rate monitoring. It also isn’t waterproof.
