We have bought and tested over 50 of the best fitness trackers on the market over the past 4 years. For our 2020 edition, we look at the 13 most compelling models currently available and comprehensively tested them head-to-head all to help you find the very best. We walked dozens and dozens of miles and tracked workout after workout to compare the fitness impact of each model, as well as looked at the various health impacts and overall ease of use of each tracker. Read on to see which wearables are worthy of awards and which is the best bet for you, regardless if you are looking for the best of the best, the most in-depth fitness tracking data, or if you are shopping on a budget.
Best Fitness Trackers and Activity Monitors of 2020
Best Overall Fitness Tracker
Fitbit Charge 3
One of the newest additions to our review, the Fitbit Charge 3 immediately swept away the competition and claimed the highest overall score we have seen in the past two years of testing these products. Needless to say, this product easily claimed the Editors' Choice Award and the title of Best Overall Fitness Tracker. This wearable is very accurate, has tons of different activities that can be tracked, and is very comfortable — all in a sleek and stylish form factor. The Fitbit Charge 3 also has some of the most extensive set of social functions, allowing you to compete and compare your fitness progress with your friends and family.
The Fitbit Charge 3 does lack a built-in GPS module, relying on your phone's, so you should definitely consider other products if you need the GPS data and don't plan on bringing your phone with you. Additionally, it can also be really hard to read the screen on the Fitbit Charge 3 in bright sunlight — especially if you are wearing certain types of polarized sunglasses. These flaws are relatively minor and the Fitbit Charge 3 is definitely the best you can get for the majority of people.

Best Basic Tracker
Xiaomi Mi Band 4
Improving on its predecessors, the Xiaomi Mi Band 4 packs even more functionality into a compact package that won't break the bank. This budget fitness tracker is very accurate when it comes to counting steps and has an alright set of other tracking abilities. It packs a surprising amount of functionality in a compact and lightweight package, making this a great option if you would rather your wearables have some discretion compared to making a style statement. It's water resistant enough to take in the pool for swimming workouts and the display is quite nice. The Xiaomi Mi Band 4 is also one of the simpler and more intuitive to use trackers, due to its simplistic nature.
However, you will be disappointed if you are expecting much more than the most rudimentary fitness tracking and smart features. It doesn't have an integrated GPS module, relying on a connected GPS through your smartphone to get most of the date for cycling or other outdoor workouts and offers very little in the way of community compare functions. The Xiaomi Mi Band 4 is a great option for anyone who doesn't need all the features of a top-tier smartwatch or fitness tracker — and doesn't want to pay for it — but still wants to keep basic tabs on their level of activity throughout the day and track their workout progress.

Best Bang for the Buck
Fitbit Inspire HR
If you want as much performance as possible without blowing your budget, then the Fitbit Inspire HR is an absolutely fantastic choice. This wearable packs an impressive amount of fitness and health tracking capabilities into a tiny package and is also surprisingly accurate — at least when tracking your steps and workouts. The Fitbit Inspire HR has a great display that is very responsive and can display all sorts of smart notifications. It's simple and easy to use, having all the critical features you want in one of these wearables without a ton of fluff to keep it friendly on the wallet.
However, it does make some concessions to keep the cost down. Namely, this tracker does lack a built-in GPS unit, instead relying on a connected GPS through your smartphone, so you will need to bring it along with you if you want to get the most out of the Fitbit Inspire HR. It also isn't the most universally comfortable tracker we have encountered, but is fine for most people. Additionally, we didn't find the heart rate monitor to be amazingly accurate in our tests, but it will give you a rough idea of how hard you are working. Overall, these flaws are relatively minor for most people and we highly recommend this model to any budget-conscious shopper looking for a new wearable.

Don't Need the Heart Rate Monitor?
If you are shopping on a budget and aren't looking to track your heart rate or get the most detailed fitness measurements, then the Fitbit Inspire is another great option. It costs a decent amount less than its sibling, the Fitbit Inspire HR, and gives you access to all the features and functions that the Fitbit ecosystem of wearables offers. It has plenty of different ways that you can challenge and compete with your friends and family, as well as provide some assistance when trying to maintain a diet. It's water-resistant to the point that you can take it in the shower or pool without issue and overall looks pretty good.
Unfortunately, this is definitely not the tracker for you if you are looking for more detailed training metrics. It is severely deficient compared to the top-tier models in terms of the data it provides you after a workout and isn't a good option for someone undergoing more serious athletic training. The Fitbit Inspire is a great option if you are shopping on a tight budget and want a basic tracker that you can use to count your steps and challenge your friends but if that isn't the case, then you will probably want to upgrade to a more feature-rich wearable.

Best for the Tightest of Budgets
LETSCOM ID115Plus HR
If the Fitbit Inspire is out of your price range and you are looking to spend the bare minimum on a new fitness tracker, then we would recommend the LETSCOM ID115Plus HR. This model scored close to the bottom of the group but retails for less than half what most of the other products typically go for. It does a good job of tracking your step count, looks alright, and is fairly easy to use but that's about it.
The LETSCOM ID115Plus HR didn't prove to be very accurate in our heart rate monitoring tests, having an average discrepancy of 40 bpm from the chest strap we used as a control, and its workout tracking only gave limited information. It's a good option if you are trying to spend as little money as possible but otherwise, we would recommend upgrading and spending just a bit more. It gets the job done but definitely could be improved.

Considering a Smartwatch?
Fitbit Versa 2
While the Fitbit Versa 2 is a bit more of a smartwatch than a fitness tracker, we feel it's worth mentioning here. It's a very fitness-focused smartwatch that gives you all the benefits of the other Fitbit trackers, as well as allowing you to install third-party apps, like Starbucks and Uber, or even use it to pay at NFC contactless terminals if you get the special edition. The screen is much nicer than most of the other trackers and it's quite comfortable to wear, even if it is a big larger.
However, this increased functionality does mean that it costs a bit more than a typical tracker and its battery life won't last as long. It doesn't cost that much more than top fitness trackers and is worth considering if you are shopping for the best and think that you would benefit from the extra smart features.

Why You Should Trust Us?
We have been testing and comparing fitness trackers at TechGearLab for close to four years now, buying all of the products in our review and updating it whenever any new or promising products have been released. We buy all the products ourselves so you can be sure that we have absolutely zero financial incentive to pick one product over the other. Austin Palmer and David Wise lead our fitness tracker testing team with their extensive experience when it comes to these products. Both have reviewed dozens and dozens of fitness trackers, smartwatches, and other wearables, as well as hundreds of other tech and smart home products. In addition, both lead very active lives and have used the products in their day-to-day lives for things like interval training cardio workouts, hiking, mountain biking, skiing, and stand up paddleboarding.
To start, we spent a substantial amount of time researching these trackers, comparing specifications and features, and reading through user reviews and experiences to determine what qualities the best fitness tracker would have, and designing a testing regimen to crown the award winners. We conducted tons of different side-by-side tests against baseline data to score the accuracy of these trackers when it came to things like RMR, heart rate, steps, and distance. Additionally, we also enlisted the help of a diverse panel to judge things like the comfort and appearance of each tracker.

Analysis and Test Results
Exploding in popularity in the past few years, fitness trackers and other wearable pieces of technology have become one of the new hot items. These are designed to improve your fitness by measuring your progress towards various goals and maximize your motivation by integrating you into a community of like-minded individuals. We split our testing process into five distinct metrics: Fitness Impact, Health Impact, Ease of Use, Ergonomics, and Display. Each model of tracker received a score in each metric, and these were combined to determine the overall score. We detail exactly what each tracker did well and where it struggled in the following sections.
Related: Buying Advice for Fitness Trackers
If you are trying to maximize your value dollar for dollar, then the Fitbit Inspire HR, the Samsung Galaxy Fit, or the Xiaomi Mi Band 4 are all fantastic options. While the Xiaomi Mi Band 4 does have a more limited set of functions than the top models, it can count your steps and track the distance traveled quite well, all for a price much lower than the top trackers. However, the Mi Band 4 is a bit limited when it comes to competing and challenging your friends. The Fitbit Inspire HR has a few more features and gives you an excellent set of community compare functions, but this increase in performance comes with a corresponding increase in cost. The Samsung Galaxy Fit is comparable in price to the Fitbit Inspire HR and has a similar set of features but will integrate just a bit better with a Samsung phone than the Fitbit models will.
The LETSCOM ID115Plus HR is While the Xiaomi Mi Band 4 is the best bet if you are shopping on the tightest of budgets, the Fitbit Inspire HR or the Samsung Galaxy Fit are for the shopper who doesn't want to make too many concessions when it comes to performance but is still budget-conscious. If you want the best of the best, then the Fitbit Charge 3 is the clear choice, though it costs quite a bit more than most of the other products to get the standard edition and even more for the special edition that includes mobile payment capabilities.
The most important metric in our test, and the primary reason that many people will purchase one of these products is to improve their fitness. We rated the products on how the community could motivate you, as well as what activities and workouts each device could track. While health and fitness are arguably the same thing, or at the very least, substantially intertwined, we focused primarily on how well each tracker did at recording physical activities in this metric, leaving things like diet and sleep tracking for a separate metric.
We manually counted how many steps it took to walk a mile course with a mechanical tally counter, then compared it to each tracker on the same course. After multiple trials for each tracker, we computed the average error. We also tested the tendency to record false steps off random arm movements. Finally, we checked how each tracker did at monitoring a high-intensity cardio workout, a cycling workout, and if any models had special features focused on other physical exercises. Overall, these tests combine to account for 30% of the total score for each tracker.
Earning the top score of the entire group when it came to fitness impact, the Fitbit Charge 3 earned an 8 out of 10 for its stellar showing. This tracker is highly accurate when it comes to calculating steps taken, stairs climbed, and distance traveled. It perfectly counted the number of stairs climbed in our tests and the step count was within 0.05% of the true count in each of our trials. The distance measurement was similarly accurate, showing a distance within 0.05 miles of the true count. It has extensive metrics on cycling and other workouts — though it does rely on your smartphone's GPS unit to maximize its tracking abilities — and has a whole host of profiles for different trackable activities.
Next in the rankings were the Fitbit Inspire HR, Garmin Vivoactive 3, the Samsung Gear Fit2 Pro, the Garmin Vivosmart 4, and the Samsung Galaxy Fit all earned a 7 out of 10 for their fitness tracking abilities. The Garmin Vivoactive 3 is a smartwatch-style fitness tracker. It has a ton of activity profiles for every activity you might do, such as ski, snowboard, XC skiing, SUP, yoga, or golf — to name just a few. It has a built-in GPS module, allowing it to do a great job at tracking different workouts and is very accurate at counting steps.
The Samsung Fit2 Pro tracks steps exceptionally accurately and provides a handful of metrics for a variety of different activities, such as hiking, elliptical, yoga, pilates, and swimming. This tracker has a particularly impressive set of swimming features, even calculating your SWOLF score while you swim. We also liked that it was quite adept at automatically recognizing an activity and would begin tracking automatically. However, we found its set of community compare features to be a bit sparse and it did an abysmal job at accurately tracking flights of stairs climbed.
The Fitbit Inspire HR offers the same number of trackable activity profiles and community compare features as the Fitbit Charge 3, but it wasn't as accurate. It didn't seem to line up as well with our baseline measurements when it came to estimating RMR and didn't prompt you to use the connected GPS for other workouts and didn't monitor elevation gained or lost while cycling. However, it was close when it came to step counts, only having an average discrepancy about 1% higher than the Fitbit Charge 3's step count error.
The Samsung Galaxy Fit performed similarly to the Samsung Gear Fit2 Pro and impressed us with its accuracy when it came to counting steps, having an average error of about 0.5% in our mile-long walk test when compared to a manual step count. This was when we started the Samsung Galaxy Fit tracking manually - we found the automatic workout tracking usually underreported the amount of steps taken, since it took a little time to kick in.
The Samsung Galaxy Fit provides a standard set of data for cycling workouts but does rely on the GPS unit in your phone to collect some of the data. You also have a decent set of different activities to choose from, including swimming, where the Samsung Galaxy Fit will also provide some swimming specific data. Unfortunately, it doesn't show the number of stairs climbed each day.
The Garmin Vivosmart 4 did just a tiny bit better than the Samsung Galaxy Fit and the Samsung Gear Fit2 Pro in our step counting test, only showing an average error of 0.28% after our three trials. However, the Garmin Vivosmart 4 fell a little short when it came to cycling tracking, since it doesn't have a dedicated biking mode. We used the running mode for our tests but weren't overly impressed with the results, as they seemed to be a bit off of what we would expect when comparing them to Strava. It has a decent amount of other trackable activities — including swimming! — and did comparable to the Samsung Galaxy Fit at tracking a cardio workout. It does track stairs climbed but did miss a few in our experience.
The Fitbit Versa 2 is on par with the top fitness trackers when it comes to this metric, offering tons of different trackable activities and a very accurate step and distance counter. It connects to your smartphone's GPS to get GPS-based data and caught most of the flights of stairs climbed.
Next, the Garmin Vivosport, earned a 6 out of 10. Though stair tracking is available on the Garmin Vivosport, it performed abysmally, only counting three out of the ten flights of stairs in our test. The Garmin Vivosport has a built-in GPS module, allowing to accurately track and monitor a variety of metrics while you are working out. It is very accurate at counting steps, though it did show a slightly larger discrepancy from the true manual count than the Garmin Vivoactive 3. However, it does have a much smaller set of activity profiles to choose from and wasn't terribly accurate at tracking flights of stairs climbed in our tests.
Rounding out the bottom of the pack, the Garmin Vivofit Jr. 2, the Fitbit Inspire, the LETSCOM ID115Plus HR, and the Xiaomi Mi Band 4 all earned a 5 out of 10. The Garmin Vivofit Jr. 2 is limited to tracking steps and timing activities exclusively, lacking the sensors for heart rate or stair climbing.
The Xiaomi Mi Band 4 did exceptionally well at accurately counting steps, holding its own against other models that cost significantly more. We calculated an average error of only 0.19% off of the manual count but the estimated distance was off by an average of 0.05 miles — not atypical for a non-GPS tracker.
It did do well in our cycling test, providing a veritable plethora of statistics when connected to your phone, and even has some swimming specific data for when your workout takes you to the water.You can select some other activities but for the most part you just get a timer of how long you were working out and some other basic stats when not connected to your phone. This tracker also does not measure the flights of stairs climbed each day.
The Fitbit Inspire did quite well in our step counting test but we found it to be a bit uninspiring when it came to tracking workouts. You can't manually start tracking and need to wait for the Fitbit Inspire to automatically detect you are working out, which we didn't find to be the most reliable. It also won't track anything besides active minutes, duration, and estimated calories burned. It also won't track the number of stairs climbed
The LETSCOM ID115Plus HR did well in our step counting tests, matching the accuracy of the Garmin Vivosmart 4 with an average error of 0.28%. Unfortunately, it only gives basic workout metrics, like speed, pace, duration, and distance, along with HR zones and doesn't have the largest library of trackable activities or a stairs climbed tracker. The Lintelek ID115HR is almost identical to the LETSCOM ID115Plus HR but earned a 4 out of 10 for performing worse in our step tracking tests.
Next, we looked at the companion apps for each manufacturer, as multiple trackers will utilize the same app. The Fitbit app led this category with its weekly emails including your stats for the previous 7 days, as well as your top 3 friends on the step count leaderboard. The app has non-competitive "Adventures", where you can digitally walk along a path to a point of interest, using your steps. There are also competitive challenges you can undertake against yourself or your friends.
Next was the Garmin Connect app, having a simpler set of features allowing you to track your progress over the past 7 days, month, or year, and allows you to opt into weekly challenges with people in your step range.
The Samsung app followed, allowing you to view your trends and duel with your friends, but lacked even more functionality than the Fitbit or Garmin apps.
Rounding out the bottom were the apps from Xiaomi, Lintelek/LETSCOM, and Polar — each of these apps only allowed you to view your past progress and offered little to no ability to challenge or compare with your friends or family.
The next highest weighted metric in this product category is the health impact of each tracker. To assess this, we started with whether or not the tracker could monitor heart rate, and how accurate it was compared to a chest strap heart rate monitor. Then, we looked at what aids in dieting each model could provide, what other lifestyle changes it could help you implement, and whether or not it could track sleep and wake you, as well as if there are any other health-specific features.
The Fitbit Charge 3 and the Samsung Gear Fit2 Pro led this metric, both earning a 7 out of 10. These models all have automatic sleep tracking, as well as a vibration wake alarm to gently wake you and leave your partner undisturbed. Our tester felt that the sleep stats reported by the Fitbit brand trackers and the Samsung Gear Fit2 Pro were very close to his recollections of the night, in terms of the number of times he woke up.
The Fitbit Charge 3 did fairly well in our heart rate tracking assessments, although the difference between the heart rate reported by the Fitbit Charge 3 and our chest strap heart rate monitor did widen considerably when our tester's heart rate became elevated when working out. We did particularly like that the Fitbit Charge 3 will remind you if you have been sedentary for too long and offers the same great access to dieting aids that the other Fitbit brand trackers do.
You can scan or search for food to help maintain a diet in the Fitbit app, as well as monitor hydration. These models all offer reminders to move every hour if you have been too sedentary, and the Fitbit Charge 3 has the unique feature of guided 2 or 5-minute breathing sessions to help you relax, while the Samsung Fit2 Pro will suggest a mini-exercise to do. The Fit 2 Pro performed a little worse, averaging about 14.5 bpm off of the chest strap.
We think the Fitbit Versa 2 also matched the performance of these top-tier fitness trackers in terms of health features. It did well in our heart rate accuracy tests, usually within a bpm or two of the control HR monitor but did periodically have larger errors — closer to 20 bpm off. It reminds you to get up and move and has convenient and easy calorie tracking with its companion app. It also has basic sleep tracking skills and a silent alarm.
Trailing slightly behind the leaders, the Fitbit Inspire HR, the Garmin Vivoactive 3, the Garmin Vivosport, and the Samsung Galaxy Fit all earned a 6 out of 10. All of these trackers have an integrated heart rate monitor but none of them overly impressed us when it came to accuracy, all showing non-trivial discrepancies from a chest strap heart rate monitor that acted as a control. The Fitbit Inspire HR was a little more accurate in our tests when it came to measuring heart rate than the others in the group, but it still averages about 10 bpm off a resting heart rate and even more off of an elevated one. The Samsung Galaxy Fit followed, usually averaging about 18 bpm off. The Garmin Vivoactive 3 and the Garmin Vivosport both were relatively subpar at monitoring heart rate, varying significantly from the measurement we took with the chest strap heart rate monitor.
The Samsung Galaxy Fit did decently well at estimating our testers' RMR throughout the day and has a basic food tracker in its app but unfortunately lacks the ability to scan barcodes to automatically fill in nutritional data. The Samsung Galaxy Fit also has some simple counters built-in to keep track of your water and caffeine intake. It will also remind you to get up and move if you have been sitting too long and will automatically track your sleep.
Both the Garmin Vivoactive 3 and the Garmin Vivosport have a noticeable vibrate in addition to producing a "move bar" on the right side of the display. The "move bar" was very helpful especially if we were distracted at the time and didn't feel the light buzz. These models both did an alright job sleep tracking and required you to use a third-party app to track calorie intake. This pair also has some basic sleep tracking abilities and a vibration alarm clock.
We did like how easy the Fitbit app makes it to track calories consumed, but we were a little disappointed with how off the Inspire was our base estimate when it came to calculating approximate RMR — it had a much larger discrepancy than the other Fitbit trackers. However, the Fitbit Inspire HR does remind you to get up and move and has both a silent alarm clock and automatic sleep tracking.
The Xiaomi Mi Band 4, the Fitbit Inspire, the Garmin Vivosmart 4, the LETSCOM ID115Plus HR, the Lintelek ID115HR, and the Garmin Vivofit Jr. 2 all earned a 5 out of 10 for their middle-of-the-road results. The Garmin Vivofit Jr. 2 and the Fitbit Inspire completely lack a heart rate monitor but the Xiaomi Mi Band 4 and the Garmin Vivosmart 4 did alright in our HR accuracy tests. The LETSCOM ID115Plus HR and the Lintelek ID115HR both have heart rate monitors but didn't score well in our tests, frequently exhibiting large discrepancies from our control chest strap monitor.
The Xiaomi Mi Band 4 doesn't estimate daily calorie burn, only active calorie burn and lacks the ability to connect with MyFitnessPal. It will remind you to get up and move if you have been sitting for too long and does have automatic sleep tracking, though we weren't the most impressed with the data it produced.
The Garmin Vivofit Jr. 2 is designed primarily for children, with in-app games that are designed specifically to get them up and active. The more active you are or the more chores you complete, the more in-game currency you acquire.
The Fitbit Inspire does have some impressive integrated dieting features but only has some basic sleep tracking features. The Garmin Vivosmart 4 does have much more detailed sleep tracking data but requires you to use a third-party app for diet tracking and doesn't remind you to get up and move if you have been sitting for too long.
The LETSCOM ID115Plus HR and the Lintelek ID115HR only offer limited sleep tracking information and can't offer much if you are currently dieting but they do have a vibration alarm clock and will notify you if you should get up and walk around.
Ease of Use
Next, we analyzed how easy each tracker was to use. These products are meant to be worn daily, and something that is difficult to use isn't exactly conducive to wearing on a daily basis. We evaluated the battery life, how intuitive the device and app was, how difficult it was to sync data from the device to the app, how hard it was to put on the device, and whether or not it was water resistant.
Leading this set of tests, the Fitbit Charge 3, the Fitbit Inspire HR, the Fitbit Inspire, the LETSCOM ID115Plus HR, the Lintelek ID115HR, the Xiaomi Mi Band 4, the Samsung Gear Fit2 Pro, and the Garmin Vivofit Jr. 2 all earned an 8 out of 10. The Fitbit Charge 3 has a very intuitive layout of menus on the device itself and we found the Fitbit app to be one of the most user-friendly in general. This tracker has a battery life that purportedly lasts for up to 7 days — depending on use — and syncs your data quickly and reliably to your smartphone whenever you open the app. The wristband has a nice stiffness and the traditional watch clasp make it very easy to put the Fitbit Charge 3 on or take it off and it is rated as being water resistant to 5 ATM — though we did miss any sort of physical interface, like a button.
The Fitbit Inspire HR performs almost identically to the Fitbit Charge 3 in this metric, but its battery life is just a little bit shorter, only lasting for up to 5 days instead of 7 days. It's just as easy to put on and is water resistant enough to take it in the shower or the pool. Additionally, we thought it was just a tiny bit more responsive than the Fitbit Charge 3. The Fitbit Inspire is almost identical to the Fitbit Inspire HR when it comes to ease of use but it can be just a tiny bit more work to put on with its alternate clasp.
The LETSCOM ID115Plus HR and the Lintelek ID115HR again scored the same, with these two trackers almost being indistinguishable from each other. They are overall very simple and minimalistic fitness trackers, making them very easy and intuitive to use. They both have a claimed battery life of up to 5 days with the HR monitor enabled and 7 days without. Both of these trackers are easy enough to put on but aren't rated as being safe to take in the pool according to their manufacturers.
The Xiaomi Mi Band 4 is a little more difficult to put on, forgoing the traditional watch clasp, but isn't too bad. This fitness tracker is rated to be water resistant to 5 ATM, or 50 meters, so you can be more than confident taking it in the pool with you. It is one of the easiest trackers to use when it comes to navigating through the menus, relying on both a touchscreen and a single-button interface, with an app that is equally intuitive to navigate. It has a solid battery life, lasting for a claimed 20 days depending on use.
The Samsung Gear Fit2 Pro is also water resistant to 5 ATM, but is a little more difficult to navigate the menus. It's not overly difficult, it just takes a little time to become accustomed to where everything is. However, we did find the battery life on the Samsung Fit2 Pro to be wanting.
The Garmin Vivofit Jr. 2 also relies on a coin cell battery, but it is water resistant to 5 ATM. It is also very easy to navigate through the menus on this tracker and the simplified Vivofit Jr. app is much easier to use than the original Garmin Connect app.
The Fitbit Versa 2 is a little bit more difficult to use, mainly due to its larger library of features to navigate through. However, it is water-resistant to 50 meters/5 ATM, is easy to put on or take off, and has a straightforward app — the same as the other Fitbit trackers. It does have a slightly shorter battery life, typically lasting for 3 days but can be anywhere from 2-5 depending on usage. Its third-party apps are also very easy to use.
The Samsung Galaxy Fit and the Garmin Vivosmart 4 came next, both meriting a 7 out of 10. This tracker has an alright battery life, lasting for up to 7 days according to Samsung, and quickly and reliable syncs your fitness data with the app. The screen is responsive and it's easy to navigate through the menus on both the device and the app. The Samsung Galaxy Fit is also rated for 5 ATM or 50 meters of water but we weren't a fan of the watch band. It's much more difficult and finicky to put on than other models, sometimes feeling like you need a third hand to do it properly.
The Garmin Vivosmart 4 has a similar battery life as the Samsung Galaxy Fit, claimed to last up to 7 days, though using the pulse oximeter or sleep tracking functions can cut into this. It syncs your data to the app fairly quickly and both the menus on the app and the tracker are easy to navigate through. It has a nice watch-style band that is easy to take on and off and the Vivosmart 4 is water-resistant enough to take in the pool.
The Garmin Vivoactive 3 and the Garmin Vivosport followed, each receiving a 6 out of 10. The Garmin Vivoactive 3 and the Garmin Vivosport are similar, lasting for up to 7 days with normal use and 13 and 8 hours respectively when the built-in GPS module is being used. As mentioned above, the Garmin app is a little confusing, and we found that some of these models tended to have some syncing issues in our tests, tending to display some sort of error at first, but then syncing successfully. There weren't many on-device menus to navigate through on this group of trackers, but they were straightforward in their simplicity. All of these are easy to put on, and rated to 5 ATM of depth.
Ergonomics was a much simpler test for these products, split into three aspects: comfort, aesthetics, and profile design — the likelihood that the fitness tracker would become snagged when performing various common tasks, such as putting on a windbreaker or a backpack.
The majority of the models tied for the top position, with the Fitbit Charge 3, the Samsung Gear Fit2 Pro, the Garmin Vivosport, the Garmin Vivosmart 4, and the Xiaomi Mi Band 4, all earning a 7 out of 10 in this metric. These models all have a relatively low-profile, making it easy to put on a backpack or a light jacket without any of the trackers getting caught.
The Vivosmart 4 and the Xiaomi Mi Band 4 are very similar in size and overall form factor. Consequently, our testing panel rated them all about the same, finding this duo of trackers very comfortable to wear. This pair was followed by the Garmin Vivosport, the Fitbit Charge 3, and the Samsung Gear Fit2 Pro all of which our judges found to be just a tiny bit less comfortable to wear. These all have very slim profiles that hardly ever get caught, with the exception of the Fitbit Charge 3, which is a tiny bit heftier.
The Fitbit Charge 3 is, in our opinion, the most visually stunning of the group, available in an attractive variety of colors. The Samsung is a close second. The Samsung Fit2 Pro stood out for its overall sleek and stylish design, including its curved screen
The Xiaomi Mi Band 4 and the Vivosmart 4 are pretty run-of-the-mill when it comes to looks for these products, all essentially black plastic rectangles of varying dimensions. The Garmin Vivosport improves on this, having a slightly sleeker, rubberized exterior available in a variety of colors.
Next, the Fitbit Inspire HR, the Fitbit Inspire, the Samsung Galaxy Fit, the Garmin Vivofit Jr. 2, and the Garmin Vivoactive 3 all merited a 6 out of 10 for their slightly above average ergonomics. The pair of Garmin models are both similarly comfortable, though the Garmin Vivoactive 3 has a larger profile due to the built-in GPS module. However, the Vivoactive HR and Garmin Vivofit Jr. 2 manage to maintain a much lower profile than many of the others, hardly ever snagging on anything.
The Garmin Vivoactive 3 is overall visually striking, while the Garmin Vivofit Jr. 2 stands out by its patterned exterior, adorned with motifs from popular franchises and movies.
The Fitbit Inspire HR and the Fitbit Inspire both have a very minimalistic design and a very low profile, but some of our testers found that the heart rate sensor of the Inspire HR protrudes slightly from the back of the watch, making an uncomfortable pressure point.
We thought the Samsung Galaxy Fit is considerably more comfortable to wear than the Fitbit Inspire HR or the Fitbit Inspire but is also considerably less stylish. However, it has an equally low profile.
The Fitbit Versa 2 isn't the most ergonomic, being a bit bulkier than some of the smaller trackers. However, it does have a sleek and stylish design and a low enough profile to keep from getting snagged too frequently.
The LETSCOM ID115Plus HR and the Lintelek ID115HR came next, both earning a 5 out of 10. These are both relatively plain when it comes to looks and don't have a huge profile but they aren't the most comfortable models we have tried to date.
The final rating metric that we looked at for this category was the quality of the display, which is responsible for 10% of the final score.
We evaluated the clarity of information displayed, whether or not the tracker could substitute for a watch, how visible the screen was in different lighting conditions, its responsiveness, what notifications could be displayed, and what other information was shown on subsequent screens. All of these models enter a sleep mode when you are not adjusting settings on them to conserve power, so we defined responsiveness as how easy it was to wake up the device to initiate a workout or look at your progress, and how easy it was to control the device through the touchscreen and buttons.
Delivering the best performance in our set of display assessments, both the Garmin Vivoactive 3 and the Garmin Vivosport earned a 9 out of 10. These both have exceptionally nice displays, particularly standing out by how easy they are to read in bright sunlight and in low light conditions. These trackers both had highly responsive touchscreens and can display almost every push notification that your smartphone can get, even allowing you to accept or deny a call.
Next up, the Samsung Gear Fit2 Pro and the Samsung Galaxy Fit both earned an 8 out of 10 for their superb display. Samsung knows their way around screens, with these two products being no exception. The Samsung Fit2 Pro is very responsive and can receive practically almost all of the notifications that your smartphone can. It is reasonably visible, even in bright conditions, but only when you activate "Outdoor Mode" which maximizes the brightness for five minutes. We found this to be slightly more of a hassle than other trackers, dropping the Samsung Fit2 Pro's score a tiny bit.
We thought the Samsung Galaxy Fit is even easier to read in bright sunlight than the Samsung Fit2 Pro and is equally responsive. The display overall looks great but doesn't show quite as much information on subsequent displays as the Samsung Fit2 Pro — not unexpected, as the screen is much smaller.
The Fitbit Versa 2 has a great display that is clear and easy to read. It shows tons of information and even lets you respond to messaging notifications, as well as showing most push notifications that your phone can receive. The screen is a lot easier to read in bright light than most other trackers and the touchscreen is very responsive to taps and swipes.
The Fitbit Charge 3, the Fitbit Inspire HR, the Fitbit Inspire, the Garmin Vivosmart 4, and the Xiaomi Mi Band 4 all finished next, earning a 7 out of 10. The Fitbits all show any smart notifications that your phone can, but it can be hard to read them in bright sunlight. The Xiaomi Mi Band 4 is a little easier to read in bright light but is more prone to missing a swipe or tap than the Fitbit Inspire HR, Fitbit Inspire, or Fitbit Charge 3. The Garmin Vivosmart 4 is plenty responsive and can also show most push notifications but it can be hard to read in bright light.
Next, the Garmin Vivofit Jr. 2, the LETSCOM ID115Plus HR, and the Lintelek ID115HR all earned a 6 out of 10 for their display. The Garmin Vivofit Jr. 2 cannot receive smart notifications, but we found it relatively easy to read, even in bright conditions. Its screen reasonably responsive, though the information they display is a little limited.
You do need to be fairly deliberate with your taps on the screens of the LETSCOM ID115Plus HR and the Lintelek ID115HR for them to register but the touchscreen is otherwise quite responsive. This pair can also receive most push notifications your smartphone gets but aren't the easiest to read in full sunlight.
It can be difficult to sift through all the currently available models and information to find the perfect fitness tracker for you. Hopefully, this review has helped you narrow down your search to a specific type, and given you a little more info on what each one does well… and not so well.
