If you're looking to get serious about your fitness, pay more attention to patterns in your health, or even just increase your daily step count, a fitness tracker or smartwatch is an incredible tool in helping you accomplish that. Sure, you can head out for a quality run or try a few breathing exercises to lower stress levels without a smart device on your wrist, but fitness wearables give you far more insight into your every movement and feeling than you may even know.
One of the brands at the forefront of the industry is Fitbit, a company whose wearables track everything from your daily step count and workout pace or intensity level to your sleep patterns and stress levels. They can help you better understand when you should be pushing yourself more in a workout to see more progress, when your stress levels are too high and you need to take a moment to decompress, and when that fatigue or irritability is actually the result of poor sleep quality.
As an avid runner, personal trainer, and fitness journalist, I've tested more fitness trackers than I can count, even before they became a staple on most people's wrists. My first tracker, the Fitbit Flex, would light up with just a few red dots to notify me that I'd hit my step goal for the day. At the time, this was revolutionary information and I loved it. Since then, I've tried countless smartwatches and fitness trackers from brands like Apple, Garmin, and Polar.
Over the past several months, I've tested out the latest in Fitbit's current lineup. My experience using them on runs, hikes, running errands around town, and even sleeping can hopefully help you decide what fits best with your lifestyle and which may be able to help you reach your own fitness and health goals.
Here are the best Fitbits for every need:
Best Fitbit overall
With automatic activity tracking and a huge screen for both mid-run stats and the relax app, the Versa 3 has nearly all the perks of the Fitbit line at a not-totally-absurd price point and with a stylish design.
Pros: Automatic activity and sleep tracking, in-depth exercise and sleep stats, 24/7 heart rate tracking, heart rate zones, built-in GPS, water resistant up to 50 meters, oxygen saturation reading, mindful minutes, battery life
Cons: Occasionally uncomfortable, sometimes needs to be manually synced
The Versa 3 stands out for its bright, colorful face and big display that clearly shows any stats. It stores about six-days' worth of battery life, and charges in just under 15 minutes. There are a lot of pros to this watch:
During a run or bike ride, this is especially great for quick glances at your pace in real time as you move. You can also easily check other stats — total time, average pace, heart rate zones — just by tapping the watch face. That's easy to do while you're mid-activity. Plus, the device buzzes to let you know when you've switched between fat burn, cardio, or peak zones. You also have the option to enable auto-pause.
In the Fitbit app, you can to see the complete overview of your cardio numbers, including time spent in those various heart rate zones, active zone minutes, average, minimum, and maximum heart rate, calories burned, and steps taken. With all this data, the Fitbit also determines your VO2max, the top marker of fitness level.
The Versa 3 has built-in GPS, so you can also go for a run or walk without your phone, which I particularly love to unplug and focus on your steps without losing the data behind how many I got in today.
In addition to straight cardio workouts, you also have easy shortcuts to workouts like bootcamp, Pilates, yoga, circuit training, and weights. What's more, the Versa 3 has one of my favorite features on any Fitbit: the automatic tracking, so when I forget to hit start on my runs, it still records all the miles.
The sleep tracking on the Versa 3 also stands out among other devices in the line, as it reveals your time awake, in REM, deep sleep, and light sleep, plus the percent of time you spend below resting heart rate (aka "restoration"). All these stats lead to an overall sleep score that makes it easy to see the quality of your sleep — which is eye-opening when you can connect your morning grogginess with a low sleep score.
You also get health-promoting tips based on sleep and activity, like when the watch told me I spend more minutes in deep sleep on days my step count hits more than 11,000 (fascinating!).
The final thing worth mentioning about Fitbit in general is the relax app. This comes on each watch, but it's best on the Versa 3 because you just have to press play and it gives you a pretty visual the Versa's large screen. You then just follow along for deep inhales and exhales. You can check the mindfulness tap on the Fitbit phone app to see what your starting and ending heart rate is, as well as log how you're feeling from very calm to very stressed.
The Versa 3 (as well as the Sense) will connect to Amazon Alexa or Google Assistant to help you check off errands or set reminders, without your computer or phone. You can even pay through the watch. Lastly, you can control music from Spotify, Pandora, or Deezer, and even answer calls right on the watch face. If you have an Android, you can send voice-to-text responses, too.
Thanks to an update in November, you can also track your blood oxygen levels through the night (you just have to download an extra app), which may be especially helpful in COVID-19 times.
The only big downfall to the Versa (and the Sense) is that sometimes the watch band stuck to my skin — especially at night or when I didn't dry it off after a workout. I do have sensitive skin, but it left a mark at one point, which went away quickly.
Also, because I close all the apps on my phone pretty often, sometimes I'd need to manually sync the watch to the phone app to see my full list of stats. This sometimes took longer than I wanted it to, especially after software updates.
Lastly, this is certainly not the cheapest watch on our list, but it still comes in below competitor models like the Apple Watch.$229.95 from Best Buy $229.95 from Amazon $229.99 from Target $229.95 from Fitbit
Best Fitbit for health-tracking
The Sense smartwatch has a ton of added features, focusing on heart health and stress management, giving you a more holistic look at your well-being.
Pros: Automatic activity and sleep tracking, in-depth exercise and sleep stats, 24/7 heart rate tracking, heart rate zones, built-in GPS, water resistant up to 50 meters, oxygen saturation reading, mindful minutes, EDA scan, ECG readings, stress management score
The Sense offers a more complete picture of your health, tracking not just your physical activity but also your mental state.
For starters, the Sense offers automatic exercise and sleep tracking, and the stats that come with those readings.
More excitingly, this smartwatch offers electrodermal activity (EDA) readings. This is a measurement of tiny electrical changes on the skin which is meant to indicate your stress levels. To get a reading, you open the EDA scan app on the watch, hold your palm on the screen, and then do a mindfulness session as it reads your EDA. After, the watch will tell you how many EDA responses it calculated (fewer means you were calm), plus your starting and ending heart rate. It gives you an option to log how you're feeling (calm or stressed), too.
Using those EDA readings, heart rate data, sleep patterns, and your exercise for the day, the Sense will also give you a stress management score. I was surprised by how low my score was when I actually felt stressed, but I chalk that up to a balance of physical activity and healthy amount of sleep.
Lastly, the Sense also reads your blood oxygen levels at night and can act as an electrocardiogram (ECG) reader with the accompanying app. This means with the touch of the screen, the watch analyzes your heart rate and looks for atrial fibrillation (or AFib, which shows an irregular heart contraction and can signal a major health issue).
The less flashy but super useful features including the ability to answer calls via Bluetooth, sync your calendar, pair the watch with Alexa or Google Assistant, and pay through your watch. You also get about six days of battery life.
To get all these features, you do have to pay a rather hefty price, and it can take some time to add things like EDA scanning to your regular health routine. But if you're trying to seriously clean up your overall health or want accountability to stay on track, the Sense's many features are worth the price.$326.00 from Best Buy
Best Fitbit for fitness-tracking
The Charge 4 hits a budget-friendly price point while offering stellar activity tracking in a smaller footprint than a smartwatch.
Pros: Automatic activity and sleep tracking, in-depth exercise and sleep stats, 24/7 heart rate tracking, heart rate zones, built-in GPS, water resistant up to 50 meters, mindful minutes, slim design, long battery life
Cons: Black-and-white display, smaller screen
If you want a tracker to record your workouts and daily movement with a few nice-to-haves, but you don't care about fancy features like a big, colorful screen; answering calls via your watch; or connecting with Alexa or Google Assistant, then the Charge 4 is your match.
This tracker has over 20 exercise modes and records and displays you all the stats you want from your workout: current and average exercise pace, distance, heart rate zones, total time, steps taken, and calories burned. Within the Fitbit app, you can also see a map of your run, complete with intensity zones showing where your heart rate climbed highest and dipped lowest.
The Charge 4 has built-in GPS, so you can run without your smartphone if you want your hands free or the battery is low, which is rarer for a tracker this small.
You also still have the option to sync your calendar and get alerts on events, plus you can read text messages and see when you're getting calls. The Charge 4 also comes with access to the Relax app for two minutes of deep breathing with dots to follow for each inhale and exhale instead of a video. This device also has Fitbit's in-depth sleep tracking.
The battery life on the Charge 4 can span up to seven days, which is longer than either Versas or the Sense. The design is smaller and takes up less space around your wrist, which is nice for more petite people.
However, that also makes the screen smaller for reading and navigating, which can be a huge drawback for some.$149.94 from Amazon
Best budget Fitbit
The Inspire 2 provides the standard features of Fitbit in a discreet, slim design that's comfortable on the wrist.
Pros: Automatic activity and sleep tracking, in-depth exercise and sleep stats, 24/7 heart rate tracking, heart rate zones, water resistant up to 50 meters, mindful minutes, slim design, battery life
Cons: No built-in GPS, smaller screen
If you're looking for a straightforward activity tracker that will tell you how much you've moved today and how good of a workout you got, the Inspire 2 offers the best of Fitbit's basic features and is super easy to use.
This mini-sized watch rocks the best of Fitbit's signature features, including automatic sleep and activity tracking, constant heart rate tracking, and mindfulness encouragement via the Relax app. Better yet, it has the longest battery life of all the Fitbits, lasting up to 10 days without a charge. And it comes in at under $100.
On the Inspire 2, you can get smartphone notifications like calendar alerts, texts, and calls (though you can't answer the phone on the watch). The slim design is nice for people who aren't used to something on their wrist, and the minimalist display, while small and harder to read for some people, makes it easy to see what's important without being inundated with stats and info.
The biggest downfall is that you need your phone every time you head out for a walk or run in order to track mileage and other stats.$69.98 from REI Co-Op
Best budget Fitbit smartwatch
If you're looking for a smartwatch, but don't want to spend a ton of money, the slightly older model of the Versa 2 boasts a lot of the same features as the newer model, but at $50 less.
Pros: Cheaper than the Versa 3 or Sense, automatic activity and sleep tracking, in-depth exercise and sleep stats, 24/7 heart rate tracking, heart rate zones, water resistant up to 50 meters, mindful minutes, long battery life
Cons: no built-in GPS
If you want the bigger screen of the Versa 3 and the Sense but don't need to answer calls from your watch or have a built-in GPS, the Versa 2 is a fabulous option to save a little money.
The Versa 2 has the big, bright screen of Fitbit's leading smartwatch models, albeit with a little less modern-looking display (though the clock face and straps are all customizable). It automatically tracks activity and sleep, offers a sleep score, has 24/7 heart rate tracking, and offers guided breathing exercises. It displays real-time pace and distance when you're on the move. The Versa 2 has 15 exercise modes to record, which is 5 less than the newer models, but still includes all the biggies like running, biking, hiking, swimming, weights, and bootcamps.
You can connect the watch to Amazon Alexa and control music via apps like Spotify. You also get phone notifications like texts and calls (you can't answer calls through the watch, though you can use voice replies to texts) and can pay with the watch. The battery usually lasts at least six days on one charge.
The major thing you're giving up by opting for the older model is built-in GPS. That means you'll need your phone with you when you go out for a run, walk, bike ride, or hike. But realistically, most of us take our phones with us running for safety or communication, so this might not be as big of a deal breaker as it sounds.$179.95 from Best Buy $179.95 from Target $179.95 from Fitbit
How to shop for a Fitbit
Fitbit was one of the first brands in the fitness tracking-space when it came out with its step counter. Since then, its devices have evolved with the needs of its customer base, allowing it to maintain one of the top spots in a growing market of fitness trackers and smartwatches. There are good options from other brands like Suunto, Apple, and Garmin but Fitbit continues to deliver high-quality products that excel in a few key areas:
Ease-of-use is everything when it comes to any technology, but especially a device you intend to use every day. Fitbit's found success as a brand thanks to its easy-to-use interfaces and superior activity and sleep tracking.
What makes Fitbit such a successful brand — and one worth the money — is that all its devices, no matter the price point or type (tracker versus smartwatch), come with all the foundational features you want in a health and fitness tracker. This includes the ability to automatically track sleep and activity, which is the best thing about the brand, in my opinion.
Then, all the models track pace, distance, and calories burned during your workouts, and calculate your heart rate training zones, including fat burn, cardio, and peak. For sleep, you not only get the total hours you slept, but the time you spent in deep and REM sleep, plus the percentage of time you spent below your resting heart rate.
With some models, these stats are easier to access than others — namely, the Sense, Versa 2, and Versa and 3 because their larger screens are easier to read at a glance. But even with the smaller, more narrow faces of the Charge 4, the numbers are very large which is really nice to have. The Inspire 2 is definitely the hardest to glace stats quickly off of.
The Fitbit app itself, accessed via your phone, is easy to navigate and clearly displays steps, miles, active zone minutes, daily calorie burn, mindfulness days, exercise, and activity per hour. It also reminders you to take 250 steps per hour. Additionally, you can track your menstrual cycle, food and water intake, and weight (though these require more manual entries).
Easy-access add-on features
Fitbit now also offers a Premium membership, through which you get access to guided meditations, video workouts, goal setting and challenges, and more in-depth health insights, particularly for your blood oxygen level readings, heart rate variability, and breathing rate.
All of these features are accessed through the Fitbit app, so this is mostly just a plus for Fitbit as a brand. However, most of the new Fitbit devices come with a complimentary free trial, after which it's $10/month or $80/year, and the upgrade unlocks special features for some devices. The Sense, for example, includes a six-month free trial of Premium, which also offers special mindfulness and mediation features through the watch's special electrodermal activity sensor. The Inspire 2 comes with a year-long free trial. The Versa 3, Versa 2, and Charge 4 all come with a 3-month free trial.
Superior battery life
Each Fitbit in the line has top-notch battery life, lasting days even with auto-activity and auto-sleep tracking turned on, so you don't have to worry about charging it every night.
Officially, the battery for all Fitbits featured last from six days up to 10 days, depending on the device and your usage. In my experience, the Versa 2, Versa 3, and Sense last an average of six days on one charge, the Charge 4 for seven days, and the Inspire 2 a whopping 10 days.
Versatile customization options
For starters, there's the devices themselves: the Fitbit line is a range of smartwatches and other wearables, all with different features and price points, so you can choose the one that best fits your style and health goals.
Then, Fitbit offers plenty of options to customize the look of your device. Each watch or tracker comes with a basic band, but all have different colors and material bands you can purchase for customization, from stainless steel mesh for a professional look to expressive prints to more breathable sports bands. The only watch on our list that doesn't offer a sport-specific band is the Inspire 2.
You can also customize the watch faces, both for aesthetics and readability, and to personalize shortcuts on the devices and what's displayed on the main app page. The Sense and Versa 3 have the most options for watch faces; you can even download third-party designs or use your own photos, which you can't do with the other models.
How I tested
In addition to testing past iterations of Fitbit trackers and smartwatches when they were launched, I tested each on the list below for several days (some weeks, even) wearing them 24/7 in most cases. I wore each during different types of workouts, from runs and walks to strength sets and yoga. I also wore the trackers to bed and for mindfulness sessions. Here are the key features I looked for when testing:
To successfully record stats during a workout and easily check these as you go, it's important that a watch clearly displays numbers, and quickly and continuously connects to the GPS, particularly if it's built into the watch. I judged the trackers and watches on whether I could easily see my current pace, distance, and time, and if I had quick access to see other metrics like average pace and heart rate.
Additionally, I ran another fitness tracking app on my phone to test the accuracy of the watch's distance and pace. For every Fitbit featured, the numbers were always relatively close (and within the normal range you'd find if you compared almost any other fitness tracker).
Because Fitbit offers automatic tracking, I also did a few workouts without manually pressing the start button to confirm that it picked up my movement, which it almost always did.
Tracking and comfort while sleeping
I wore each of these watches and trackers to bed to test the automatic sleep tracking. I checked these stats in the morning to make sure it recorded my time in bed and wake-up times throughout the night. I also wore the devices when occasionally taking naps throughout the day, which they also picked up on.
The devices needed to be comfortable enough to wear all night in order to get those stats, too. While the bands occasionally stuck to my skin if I got sweaty at night, it never disturbed my sleep — I only ever noticed this after waking up.
I tested the battery life of each Fitbit by charging it to 100% battery and wearing it through workouts, nights of sleep, and throughout the day to see how long each would last. They all surprised me, too — the life lasted even after several workouts, including those using the built-in GPS (which typically drains batteries quickly). The Inspire 2 was the most impressive for battery life.
One huge perk of Fitbit is the built-in stress-reducing apps, so how easy these were to use was a key part of testing. I tried Fitbit's mindfulness program, the Relax app, on all devices, and the EDA scan app on the Sense, which contributes to stress management numbers. I looked for ease of use, visuals, and the stats provided after recording a mindfulness session, like changes in heart rate.
