The fitness tracker offers excellent reporting including distance, speed, cadence, heart rate (if paired with monitor), ascent, decent, calories, recovery status, and more. See More

Top Pro

Detailed reports

Top Con

Short battery life when using the GPS

With the GPS turned on, battery life goes from around 24 days to 9 hours. This is likely fine for people who will always have opportunities to charge it after their run. However for anyone hoping to use the GPS for longer activities, such as hiking, that may not be long enough to be useful. See More

Top Pro

Ability to add training notes

The app allows you to add additional notes to your workouts for better tracking. See More

Top Con

Sleep tracking lacks detail and accuracy

If you are awake for an extended period of time in the middle of the night and then fall back asleep, the fitness tracker may not see the additional hours as part of your sleep. See More

Top Pro

Gives you custom activity goals suitable for your level

The daily activity goal is a good way to find out how active you really are in your everyday life. Here you can choose your typical activity level from three options and see how active you need to be to reach your daily activity goal. The time you need to complete your daily activity goal depends on the level you have chosen and the intensity of your activities. Age and gender also affect the intensity you need to reach your daily activity goal. See More

The Fitbit Blaze fitness tracker is feature-rich and tracks steps, calories burned, distance traveled, active minutes, floors climbed, heart-rate, and sleep time. See More

Fitbit Blaze

Top Pro

Tracks your activity in a large variety of ways

Top Con

Requires your smartphone for GPS tracking

The Blaze lacks a built-in GPS so it can't track the route of your runs on its own. It can, however, be paired with your smartphone to use its GPS and track the route that way. See More

Specs

GPS:Uses smartphone GPS

The Fitbit Blaze is a great option for outdoor use thanks to how easy it is to see the display even in bright sunlight. The clear and bright display uses plenty of color for better clarity. See More

Top Pro

Very easy to read, even in bright sunlight

Top Con

Poor use of the large display

The fitness tracker's screen takes up a small amount of the front face. The glass bezels and casing take up most of the front. See More

Top Pro

Long battery life for being so feature-rich

While it varies somewhat, many people have been reporting that the fitness tracker usually lasts 5 full days on a single charge. In general, the more features a tracker has, the faster it will drain the battery. 4 or 5 days is an impressive charge compared to other trackers with similar features (continuous heart rate tracking for example). See More

Top Con

Inconvenient to charge

To charge the Blaze fitness tracker, you need to remove the main module and lock it into its charger. See More

Top Pro

Interesting design

The Blaze has a techie look to it that some may find a nice change from the usual sporty-appearance of trackers. It is fairly lightweight and the design isn't offensive, it's something you can wear every day. See More

Top Pro

Wide range of wrist straps available for a more personalized look

If you don't like the basic rubber wrist strap the comes with the tracker, you can change out the strap for more premium options. There are many different styles available including leather, silicone, or stainless steel in a variety of colors. See More

Specs

Top Pro

The app and web platform do an excellent job of keeping you motivated

The Fitbit app lets you set goals and milestones which reward you with badges and trophies when reached. You can also challenge friends and family, competing against them for top spot on the leader board. See More

Top Con

Underwhelming battery life

The fitness tracker's battery lasts about 3-4 days on average. See More

Top Pro

Replaceable wristband with lots of options available

The fitness tracker itself is a separate part from the wristband that can be taken out and put in a different band. Therefore, not only are there 10 wristband colors to choose from on the official store, a different color of band can be worn every day with the same tracker. There are even custom bands available from third-party vendors. See More

Top Pro

Sleek design fits a variety of occasions

The Flex 2 is a thin band all the way around that has a modern and sleek design. Since it isn't super sporty in appearance, you can confidently wear it for a lot of different occasions without it looking out of place. See More

For its size, the Alta fitness tracker has a large display. The display will show steps, distance, calories burned, active minutes, and sleep time. You can switch between these by tapping the side of the display (there is no button). The screen is easy to read at a glance while on the move except in bright settings. See More

Fitbit Alta

Top Pro

Informative and clear display that's easy to read

Top Con

Difficult to see the display when outdoors

The display is quite dim which makes it very difficult to read when in bright settings. See More

Specs

Top Pro

Reminds you to move every hour

The Alta will remind you about your move alerts each hour. By default, it suggests 250 steps each hour and it will vibrate 10 minutes before each hour is over to give you enough time to accomplish the micro-step goal. See More

Top Con

The device cannot be used without a smartphone or a computer

In order to activate the device for usage, it must be paired with a smartphone and/or a PC (through a USB dongle), and an account must be registered through Fitbit. See More

Top Pro

Many different wrist band options available to suit your taste

The Alta itself comes in 4 colors: black, teal, purple and plum. While expensive, you can swap out the band. Classic bands cost $30, leather bands cost $60, and stainless steel bands cost $100. See More

Top Con

Display is off by default

To manually turn on the display you must double tap the side of the tracker which can be difficult to do properly. It can also turned on automatically by the appropriate wrist/arm movement for checking the time. There is no way to keep the display on so it may take some fumbling every time you want to look at the display. See More

Top Pro

Week long battery life

The fitness tracker's battery can last a full week before you need to recharge it - quite a bit longer than most activity trackers. See More

Top Con

Fairly basic features which limits the information you'll receive from the tracker

The Alta fitness tracker is designed to be more of a passive tracker for the Average Joe as opposed to a complete activity tracker for enthusiasts. There is no GPS or heart rate monitor, so the stats you get are limited to steps, rough distance traveled, estimated calories burned, active minutes, and sleep tracking. See More

Top Pro

Will fit almost any wrist size

The Alta is available in three different sizes (small, large, and extra large). Each size can be adjusted by a minimum of 1 inch. This is a great tracker for people with wrists below or above average size who may have trouble finding a comfortable fit with other trackers. See More

Top Pro

Lightweight and comfortable to wear

As a result of the Alta having a slim design, it is both lightweight and very comfortable to wear. See More

The display screens are fully customizable so you can control which stats you want to see. See More

Garmin Forerunner 235

Top Pro

Customize the display screen to display the data most important to you

Top Con

Has trouble tracking heart rate during intervals

Specs

Waterproof:Waterproof (50m)

GPS:Yes

Sleep tracking:Yes

Top Pro

Quickly picks up a GPS signal

It picks up the GPS signal much faster than most other GPS fitness trackers available, so there is little waiting around for it to connect before you start your run. See More

Top Con

Needs to be recharged often

Garmin states the watch has a battery life of 11 hours training and 9 days of use as a watch, which is a fairly short charge compared to other fitness trackers. However many people have found the actual charge to be much less, often needing to be recharged every couple of days. See More

Top Pro

Ideal tracker for runners

It's quite lightweight at 1.6oz and has a large bright display for easy reading while on the move in all types of lighting conditions. It's water resistant up to 50 meters so you're safe to wear it running in all types of weather. See More

Top Pro

Extremely lightweight and comfortable

When connected to the GPS on your phone, the Charge HR is able to keep track of elevation. This is a great feature for hikers who often like to know how much elevation was gained over the course of the hike. See More

Fitbit Charge HR

Top Pro

Can track your elevation so you know how high you've hiked

Top Con

My Charge HR, & my newly purchased Fitbit Aspire HR... Aren’t completely compatible w/ my iPhone 11 Pro... Texted messages DONT WORK! Working in a classroom, is the feature I need most!

Specs

Top Pro

Compatible with nearly every smartphone

In addition to Android and iPhone support, the Charge HR fitness tracker also supports Windows Phone which is fairly rare. While not an issue most of the time, when upgrading your phone you won't have to worry if your fitness tracker will work with it or not. See More

Top Con

Notifications are easily missed

While the Charge HR fitness tracker will vibrate to notify you of incoming messages on your phone, the vibration is subtle and short. Sometimes you won't notice the buzz and you'll miss the notification. See More

Top Pro

Continuously measures your heart rate and intensity level to give you 24 hour stats

Throughout the day (and night), the Charge HR fitness tracker continuously measures your heart rate. On the app, graphs show your heart rate throughout the day, providing stats such as time spent in the different zones (peak, cardio, and fat burn) as well as your average resting heart rate for that day. See More

Top Con

Band is poorly made and tends to fall apart

Usually after a few months of wear, people start having issues with the band falling apart. Bubbles will appear under the top layer of the band and then the layers start separating. The Fitbit Charge HR does not have a replaceable band, so you have to replace the whole device if it is no longer wearable. See More

Top Pro

The app and web platform do an excellent job of keeping you motivated

The Fitbit app lets you set goals and milestones which reward you with badges and trophies when reached. You can also challenge friends and family, competing against them for top spot on the leader board. See More

Top Con

Stats aren't always accurate

While good enough for most users, the data can be skewed because of physical limits of the fitness tracker. For example, an elevated pulse may just be because you chugged back a coffee, but the Charge HR may interpret this as physical activity. Also, measuring a pulse and steps from the wrist can only be so accurate. See More

The Fitbit Zip fitness tracker wirelessly syncs with both PC and smartphones via the Fitbit app. After getting it set up you don't even think about syncing, it's just automatic. See More

Fitbit Zip

Top Pro

Automatic synching that's easy to setup

Top Con

Lacks a rechargeable battery

The Fitbit Zip fitness tracker runs on a 3-volt lithium-ion battery that lasts between 4 and 6 months. It requires getting a new battery every time it runs out of charge. See More

Specs

Top Pro

Fitbit app lets you track a variety of health-related stats

The app doesn't only display the stats from your device, it also lets you track a variety of different health-related stats by entering them manually. You can log your food for the day, how you slept, activity, weight, and more. See More

Top Con

Issues with the battery not working

The contacts in the device are very sensitive. If you don't place the battery in just right, it will only work for a short period of time before the battery needs to be readjusted or replaced. Even when following instructions provided by the company, some people report that still can't get it working properly. The battery may end up lasting days instead of the promised 4-6 months. You can see how to properly change the battery here. See More

Top Pro

Social component to help keep you motivated

The Zip keeps you motivated through friendly competition. Along with giving you a rank among your friends, you can also cheer them on or taunt them. See More

Top Con

Lacking many of the features that fitness trackers often offer

The Fitbit Zip only tracks distance, steps, and calories burned. It's basically a pedometer with a smart tracking platform you can use for manually tracking the rest of your day. It can't tell you stairs climbed or heart rate, and there is no alarm, sleep tracking, or GPS. See More

Top Pro

Easy to hide under your clothes

The Fitbit Zip fitness tracker is very small, so you can easily wear it somewhere that it will be hidden (belt, pocket, bra strap, etc.). Unlike most trackers which have wrist bands, you don't have to worry about trying to make it blend in with what you're wearing. See More

Top Con

Easy to lose

The tiny size of the Fitbit Zip makes it very easy to lose track of. Rather than a wrist watch like many other trackers, it only has a slide on clip. The clip is fairly secure for normal activity, but you may knock the tracker off without realizing it. See More

Top Con

Only one sock is active at a time

The socks feed data to a single anklet, and information for both feet can't be gathered at the same time yet. This functionality is planned. See More

Top Pro

Provides feedback on running technique through voice messages

Sensoria fitness tracker gathers information on how a runner puts pressure on their foot and analyzes it in real-time. If the sock notices something that could potentially cause injuries, it warns the runner with a voice message and suggests a way to improve his technique. See More

Top Con

Doesn't catch some bad running techniques

Currently the fitness tracker covers a relatively small subset of bad running techniques. It's possible to be in a situation where the technique is bad and the device is not aware of it. See More

Withings Go

Top Pro

Can go up to 8 months on a single battery

Top Con

Very inaccurate sleep tracker

The Withings Go is not a good option for someone wanting accurate data on their sleep habits. It often doesn't detect times you wake up at all, or sometimes registers them as "light sleep". Many users have reported the number of hours spent sleeping being consistently off by a couple hours or more. See More

Specs

Top Pro

Very easy to read the display in all lighting conditions

The Withings Go fitness tracker uses an E ink screen, the same as what you would find on an e-reader. Rather than being lit like a usual digital screen, it is much more similar to ink on paper. This makes it very easy to read even in very bright conditions or when in the water. See More

Top Con

Known to underestimate step count

A common complaint is that the Withings Go fitness tracker will underestimate the steps taken. This is the opposite of many trackers which are often known for overestimating the step count. See More

Top Pro

The display is very simple to use

The display is wonderfully simple so there is 0 time spent on fiddling with settings and figuring out how the display works. Pressing on the display will switch between the time, and your activity progress. See More

Top Pro

Water won't cause it any issues

The Withings Go is water-resistant up to 50m. Not only can it easily handle wet weather and sweat, but you can confidently wear it swimming or in the shower. See More

Fitbit Flex

Top Pro

Quick food and drink logging

Top Con

Hard to get the tapping right to active LED display

The double tap to activate the LED display lights must be the appropriate pressure and timing in order for it to work correctly. This can be frustrating to some users. See More

Specs

Top Pro

Social layer can increase motivation

Information regarding goals and progress can be shared with friends, and users can even challenge each other with goals. See More

Top Con

Oversensitive pedometer overestimates your step count

The fitness tracker's step counter often counts movement unrelated to walking or running as steps. It ends up reporting more movement than has actually happened. See More

Top Pro

Tracks weight goals

Fitbit Flex lets users create a meal plan and log their progress from the dashboard menu. See More

Top Pro

Replaceable wristband with lots of style options available

The fitness tracker itself is a separate part from the wristband that can be taken out and put in a different band. There is 10 wristband colors to choose from in the official store, and custom bands available from third-party vendors. See More

Real-time Bluetooth syncing

Flex constantly shares data over Bluetooth, meaning that the device doesn't need to be taken off in order for the data to sync to an iOS or Android device. See More

Top Pro

Visually displays your daily progress using LED lights

There are 5 LED lights that, after double-tapping the wristband, display progress towards a goal. Each light indicates 20% progress towards the goal and the tracker allows choosing between steps, calories or distance to display this way. See More

Top Pro

Comprehensive reports of your daily activities

The fitness tracker offers stats such as distance traveled, steps taken, calories burned, weight changes, calories consumed from foods and drinks, restless and awake states of sleep, etc. See More

The tracker looks more like a regular watch, with a fairly minimal and cleanly designed watch face. You can wear it with many different styles and it will blend in. See More

Withings Activité Pop

Top Pro

Suits a variety of occasions since it doesn't look like a fitness tracker

Top Con

Watch bands are low quality and fairly unprofessional in appearance

The overall design makes it feel like there is confusion as to who the target market is for the tracker. The watch face is sleek and professional in appearance, looking more like a regular watch than a tracker. However the bands available for the watch are made from a cheap-looking silicone. If you wish to buy a replacement band, they are only available in three bright colors (orange, plum, and teal). See More

Specs

Altimeter:No

GPS:No

Waterproof:Water-resistant to 150ft

The tracker uses a battery which means no worrying about bringing charging cords with you, and the battery lasts for up to 8 months. The time automatically stays synced to your connected smartphone. So when you cross time zones, the Activité Pop will automatically adjust the time for you. See More

Top Pro

Great for people who travel

Top Con

Difficult to read in poor lighting

The watch face doesn't have a backlight and the hands don't glow, so it's near impossible to read the time in dark settings without external light. See More

Top Con

Sometimes has issues with condensation inside the glass

The watch is supposed to be water resistant up to 50m. However some of the watches have loose backs which causes condensation to build inside the watch, especially after hot showers. See More

Top Pro

Large, clear display that's easy to read

The fitness tracker has a large display that's easy to operate while on the move, so viewing your stats won't distract from your workout. The display is curved and bright so it's easy to read both in dark and bright lighting conditions. See More

Top Con

Unreliable build quality

There are many reviews on Amazon stating people had issues with the device quitting after only a few months of use. See More

Top Pro

Lots of options for personalizing the appearance

Top Con

GPS drains the battery extremely fast

Not a great option for those who want to use the tracker for long hikes. With the GPS turned on, it goes through battery extremely fast. Only lasting a few hours before needing to be put on power saving mode. See More

Top Pro

Keeps you constantly aware of your progress without needing to look at your smartphone

No activity autodetection

Vivosmart does not automatically detect when you start to walk or run, you have to start and stop activity manually. See More

Top Pro

It syncs with the iPhone.

Top Con

Reps counting feature does not work for some exercises

Reps counting feature is not reliable, sometimes it misses few reps and with some exercises it can count 1 rap, even if you did 10 reps for example. And it can't detect when you start the exercise, so you have to start and stop the counter manually. In practice I frequently forget to start and to stop the counter so after some time I simply sopped using this feature. See More
