With dozens of brands to choose from, it’s not always easy to figure out the right fitness tracker. Of course, knowing the brand you are interested in helps. If you’re on this page, odds are that brand is Fitbit. We can’t blame you — Fitbit makes a full suite of approachable wearables that will work for most people and has one of the easiest-to-use apps on the market. If you’re looking for the best Fitbit for your needs, look no further.

Our fitness team puts each new launch through in-depth tests to ensure we only recommend the best options. Keep reading to get to the results!


The best Fitbit tracker for most people is the Versa 3

Fitbit Versa 3
Fitbit Versa 3
Decent battery life • Pretty accurate health tracking • Built-in GPS
The Fitbit Versa 3 is a watered-down version of the Fitbit Sense.
If you're looking for the best all-around smartwatch at a pretty good price, you're likely looking for the Fitbit Versa 3. Fitbit's cheaper flagship smartwatch sports standalone GPS, an accurate heart rate sensor, and plenty of nice smartwatch features.

The Fitbit Versa 3 isn’t the flagship watch in the brand’s lineup — that honor goes to the Sense, which we will return to a bit later in this guide. Don’t let the Sense fool you, in almost all cases the Versa 3 is the best Fitbit you can buy. The Versa 3 takes the best features from the Sense and the Charge 5 and blends them together. We love that the Versa 3 is sleek and comfortable, despite being larger than the Charge 5. Really the only features that separate the Versa 3 from its sibling are the lack of ECG, EDA, and skin temperature sensors. If you’re not too worried about any of those features, then the choice just got easier.

Unlike most smartwatches, the Versa 3 has exceptional battery life. We consistently saw about three and a half days of battery life in our testing, including the use of sensors like the heart rate monitor and GPS. Surprisingly, it beat out the Fitbit Charge 5, which saw about three days of power in our review.

If you’re strongly considering a Fitbit, you’re probably doing so for its health-monitoring features. They are, after all, the brand’s bread and butter. The Versa 3 lives up to the family name, and we saw accurate results in step counting, sleep tracking, and most of the other basics. You also get an altimeter built into the Versa 3, a feature that Fitbit ditched in its Charge 5. This is an important measure of elevation during workouts and can give you a more accurate idea of your intensity. Fitbit also added a built-in GPS to the Versa 3, which is a first for the lineup. It worked well throughout our testing and remained accurate even in areas with a weak signal. Sure passing under bridges threw it off, but that happens with many GPS trackers.

The Fitbit Versa 3 is a fitness smartwatch done right. It packs advanced metrics with solid battery life and an approachable price.

Fitness trackers often suffer when it comes to heart rate monitoring, but we were impressed by what the Versa 3 has to offer. It’s not perfect by any means, you’ll still get better results with a chest strap, but it handled our tests pretty well. The Versa 3 isn’t the fastest when it comes to rapid heart rate changes, and it seemed worse at the start of our testing. Over time, the watch improved its readings, but it didn’t seem as fast as the Versa 2.

Sleep tracking is another one of the Versa 3’s key selling points. You can track light, deep, and REM sleep as usual, and this smartwatch adds some extra goodies to the mix. We were particularly impressed by the snore and noise detection, which analyzes noises during the night to match them with different parts of your sleep cycle. It then takes all of your data and crafts a score from 1 to 100 to give you an idea of your overall sleep quality. While Fitbit might not be as accurate as a sleep study lab, the Versa 3 performed admirably against the ScanWatch, one of our favorites for sleep tracking.

We’ve hit fitness pretty heavily, but it’s good to remember that the Fitbit Versa 3 is a solid smartwatch, too. One of our favorite features is the ability to swap out the watch face whenever we want. It doesn’t have a massive app store, but it does cover the basics like Starbucks and Spotify. You can also choose between Alexa and Google Assistant as your preferred voice assistant, and you can place calls right from your wrist.

Overall, the Fitbit Versa 3 takes top marks almost across the board. It’s well balanced between fitness tracking and everyday life and won’t hurt your wallet too much. We recommend it as our top Fitbit for most users, as it covers a broad base of metrics without adding extra sensors you may not even use.

What makes it stand out

  • Built-in GPS: Fitbit’s built-in GPS is far more accurate than the connected GPS option on previous editions. It allows you to run without your phone, and you can easily store your favorite playlist for some tunes while you rack up the miles.
  • Two voice assistants: Most fitness trackers lock you into one voice assistant or skip the feature altogether, so it’s great to have the flexibility of Alexa or Google Assistant when you first set up the watch.
  • Voice calling: Voice calling isn’t exclusive to the Versa 3, but it’s not a feature often found on affordable smartwatches. It worked nearly flawlessly in our testing and delivered similar results on Android and iOS.
  • Excellent value: There are fitness trackers that cost less and fitness trackers that do more, but the Versa 3 is an ideal middle ground. It offers most of the key features of the Sense without the extra price hike.

Best of the rest: 6 other Fitbit trackers and smartwatches worth considering

Although we recommend the Fitbit Versa 3 for most users, it’s not the only game in town. There are other watch-style options with extra features, or you can check out a band-style Fitbit for quick, easy tracking. We think the Versa 3 offers the best mix of both worlds, but it’s important to find the right wearable for your needs. Keep in mind the questions at the top of the article as you dive into the rest of our picks. Here’s the best of the rest:

Watch-style Fitbits

  • Sense: The Fitbit Sense takes top marks for health tracking thanks to its extra ECG, EDA, and skin temperature sensors. If you don’t need those, however, the additional cost might not be worthwhile.
  • Versa 2: It’s not quite as polished as the Versa 3, but Fitbit’s previous Versa 2 still offers most advanced features like apps and sleep tracking on a budget.

Band-style Fitbits

  • Charge 5: The Charge 5 is the best band-style fitness tracker, Fitbit or otherwise. It packs a crisp display and an updated design with a built-in EDA sensor.
  • Inspire 2: Fitbit’s Inspire 2 is a great value if you want to cover the basics of fitness tracking. It packs round-the-clock heart rate monitoring and is remarkably lightweight. It’s a good intro to the fitness tracking world.
  • Luxe: Fitness tracking and fashion really can go together. The Luxe features a rounded, jewelry-inspired design and a host of bracelet and strap options to match plenty of outfits. Fitbit even added SpO2 monitoring after launch.
  • Ace 3: There aren’t too many fitness trackers for kids, but Fitbit makes one of the best. The Ace 3 is light on the wrist, so your kids should be able to play all day and build healthy habits.

Fitbit Sense: The best for health tracking

Fitbit Sense
Fitbit Sense
High-end, premium design • Improved quick-release straps • Accurate GPS and heart rate sensors • Detailed sleep tracking • ~6-day battery life
The Fitbit Sense delivers on the basics, but it's clear some features need more work.
The Fitbit Sense is Fitbit's flagship health-focused smartwatch. It has built-in ECG, GPS, and heart rate sensors, plus a new EDA Scan app that measures your body's stress levels. This is by far Fitbit's most advanced health watch so far.

We said we’d return to the Fitbit Sense, and here it is. This is, without a doubt, the data junkie’s Fitbit. It’s not perfect — the sensors could use a little refining — but it offers more data than you can shake a stick at. We’ll dig into those new sensors first, as they will likely be your deciding factor between the Sense and the Versa 3. Fitbit added three helpful options: an EDA, a medically certified ECG, and a skin temperature sensor. There’s a whole lot of data to be had from the trio, but our reviewer didn’t always find health-tracking happiness.

Fitbit’s EDA sensor applies small, undetectable electrical charges to your skin to see how they interact with your sweat level. It’s intended as a way to measure how electrodermal activity influences our mental state and, therefore, our stress level. The process takes about two minutes to build a reading, but some of the data lacks explanation. For example, we experienced six EDA responses in one of our tests but got no indication whether that’s a high or low number.

While the EDA might need a few more updates to reach its final form, we’ve already seen that Fitbit is happy to add features. The Sense’s ECG was unavailable at its launch but quickly rolled out to users in select countries. It takes a few extra steps to start your reading and export the data, but our experiences lined up pretty well against ECG readouts from other watches.

Despite the hiccups here and there with new sensors, the Fitbit Sense is a king when it comes to the basics. We had no issue with the 24/7 heart rate monitoring, and the Active Zone Minutes feature is a fun way to achieve the recommended amount of activity each week. Fitbit also ported one of the Charge 5’s best features to the Sense — the Daily Readiness Score. It’s a helpful metric that suggests how much activity you should aim for each day, but it’s locked away behind a Fitbit Premium subscription.

As for pure smartwatch features, the Fitbit Sense matches its Versa 3 sibling with Alexa and Google Assistant support. It’s not the quickest implementation of a voice assistant, but Fitbit is still growing in the smartwatch market. You can also add the same library of apps and store about 500 songs, which is more than enough for a long run. The Fitbit Sense also delivered around five days of battery life in our testing — a solid mark given its bevy of sensors and love of data.

Overall the Sense is a great watch if you want something that’s stocked with all the bells and whistles, but a lot of its features might not be necessary. The batter In those cases, we again recommend the Versa 3.

What makes it stand out

  • Unreal battery life: Fitbit advertises six days of battery life, and we regularly achieved about five. It’s still an impressive tally, given that smartwatches from Apple and Samsung tend to last a fraction of that time.
  • Extra sensors, extra data: The new EDA, ECG, and skin temperature sensors give the Sense a leg up in everyday health tracking. You can get a better idea of your stress level and look for other metrics beyond your heart rate and step count.
  • Premium design: Fitbit didn’t cut any corners when it comes to the Sense. It blends a smooth design with quality materials that match the asking price.

Fitbit Versa 2: The best smartwatch if you’re on a budget

Fitbit Versa 2
Fitbit Versa 2
OLED display is a nice upgrade • Accurate fitness and health tracking • Sleep tracking/Sleep Score are very useful
The Fitbit Versa 2 is an improvement over the original Versa, Fitbit still has plenty of work to do.
The Fitbit Versa 2 offers a handful of improvements over its predecessor. The AMOLED display is a welcome change, all models come with Fitbit Pay this time around, and it's a fantastic fitness and health tracker. Fitbit is still trying to figure out the smartwatch aspect of it, though. Amazon Alexa support is finicky, and Fitbit's third-party app catalog is still lacking. But for under $200, the positives outweigh the negatives here. The Versa 2 provides an overall excellent wearable experience, albeit with some quirks.

Fitbit’s Versa 2 is a good way to bridge the gap between a band-style fitness tracker and a smartwatch. It’s available at an excellent price given the launch of the newer Versa 3 and Sense, but it’s not ready to head out to pasture yet. As an older fitness tracker, you won’t find a built-in GPS — instead requiring connected GPS — and you don’t get your choice of voice assistants. Still if you want something basic, there’s a lot to love here if you focus on the fitness tracking strengths and the creature comforts like an AMOLED display. It’s far better than the original Versa’s LCD, and the rounded glass design and simplified button setup lend a more premium feel.

In our review, we mention that the Versa 2 doesn’t fall far from the tree when it comes to fitness tracking features. If you’re leaning towards the older Versa, you’ve probably decided to focus on the basics of fitness tracking anyway. We didn’t love the need to carry a phone with us for GPS connectivity, but the Versa 2 nails most other metrics. It tackles steps, distance, calories burned, your heart rate, and sleep without issue.

Not sold on Fitbit? The best Fitbit alternatives

One of the most important additions Fitbit made with the Versa 2 was the introduction of goal-based exercises, which first appeared on the Charge 3. Essentially, they allow you to set a goal before starting a workout, and the watch will ping you when you reach it. It’s more in-depth than just running for a mile or stretching for 10 minutes — we were happy to see yoga, biking, weight lifting, and more make the list. Of course, you can always skip the goal-based workouts and head out for the generic “workout” setting, which we used to record our stand-up paddleboarding addiction.

While the Fitbit Versa 2 lacks some of the latest sensors, it’s still a formidable health tracking device. It picked up a new Oxygen Variation Graph in February 2020, which makes great use of the SpO2 sensor to approximate your blood oxygen saturation. Sleep tracking, which we explained above, is available on the Versa 2. We found the results pretty accurate compared with other sleep trackers, even without the extra sensors of the Versa 3.

While the Versa 3 and Sense are well-rounded smartwatches, the Versa 2 is a good reminder of where Fitbit came from. It only offers Alexa as a voice assistant, which tended to lag in our testing. Alexa often got stuck on the “Thinking” screen for a while when we asked questions, often leading us to turn to a different smart device. On the bright side, the Versa 2 packs NFC, so you can easily make payments from your wrist — a feature absent from the original model.

In many cases we recommend splurging for a Versa 3 or the Sense, but it could absolutely be worth the purchase if you want a smartwatch that’s good at fitness basics and available for fairly cheap.

What makes it stand out

  • Upgrades over the original: While the first Fitbit Versa was a bit of a proof of concept, the Versa 2 brings upgrades like an AMOLED display and NFC support but no built-in GPS.
  • Great value: Other Fitbit smartwatches will set you back a bit more, but the Versa 2’s age means you can typically find it for a fraction of the original price.
  • Goal-based exercises: It’s great to see Fitbit port features from one wearable to the next, and goal-based exercise means you don’t have to run or swim aimlessly until you tire out.

Fitbit Charge 5: The best band-style tracker, period

Fitbit Charge 5
Fitbit Charge 5
Bright, beautiful full-color OLED display • EDA, SpO2, and skin temperature tracking • Excellent tracking accuracy
Fitbit has launched a good fitness tracker at a very high price. The question is: why?
The Fitbit Charge 5 is a major update from its predecessor. Not only does it have a color AMOLED display, it's the first tracker to come with Fitbit's Daily Readiness Score — a feature that aims to predict how much activity or rest you should take on for the day.

There’s no doubt about it — the Charge is the classic Fitbit. It’s been usurped by the smartwatch options, but if someone says Fitbit, you’re probably thinking of the band-style tracker. The Charge has been around since the very beginnings of Fitbit back in 2014, and it didn’t alter much through the years. However, that all changes with the Charge 5. Maybe that sounds like too much hype, but it’s nice to see the original fitness tracker leap into the modern age.

After four years of a black and white display, the Charge 5’s new full-color AMOLED panel is impossible to miss. The upgraded and enlarged display makes life much easier when checking your heart rate or monitoring your SpO2, sleep, and steps. You’ll also notice that the revamped design drops the capacitive side button from the Charge 5. Instead, you’ll have to navigate with swipes and taps, which can be tricky for bigger fingers, as we quickly learned.

Despite the larger display and more complicated navigation, the Charge 5 is smaller than its predecessor, thanks partly to the rounded, smooth design. Design updates this significant might cause headaches for longtime fans — bands from the previous Charge 4 won’t fit on the new version. Another casualty of progress is the Charge 5’s battery life. We saw an average of about three days in our testing, a downgrade from five to six days in the Charge 4.

Once you move past the basics, we noticed there’s a bit of a trade-off in the Charge 5. Our reviewer was happy to see an EDA sensor join the party, but it came at the cost of the altimeter. That means you can keep an eye on your stress level, but you won’t be able to follow elevation-related measurements like the number of steps you climb. As for daily functionality, the Charge 5 finally picks up on a few of the smartwatch features from the Sense and Versa series. It’s a better way to read notifications like texts and emails, and you finally get Fitbit Pay support with NFC. Unfortunately, there’s still no music control.

In a classic case of Fitbit taketh away, Fitbit giveth back, the Charge 5 now has onboard GPS. This makes it one of the best fitness trackers, regardless of brand. It’s a solid running option, given that you no longer need to tote your phone with you, and you can easily make NFC purchases if you need a drink on the go. We noticed that the onboard GPS is a bit of a battery hog, but you can always toggle back to connected GPS to save some power. If you really want a great fitness tracker and don’t need all the smartwatch extras, there’s really no better option.

What makes it stand out

  • Revamped design: The Charge 5 is finally a departure for the long-running fitness tracker. It features a colorful AMOLED panel with on-display controls instead of a capacitive button.
  • Upgraded sensors: Onboard GPS and an EDA sensor make it easier to leave your phone behind for a run or check your stress level whenever you’re feeling tight.

So far, most of our Fitbit picks have been about giving you the most powerful fitness tracking experience. Sometimes, however, it’s better to keep things simple. That was our basic conclusion with the Fitbit Inspire 2 — it’s rock-solid on the basics, but it doesn’t totally reinvent the category. You might be disappointed if you were expecting a fully revamped Inspire HR, but it’s a great pick for first-timers.

One of the more noticeable changes from the original Inspire is a new, slightly rounded design. We weren’t necessarily inspired by it, but it’s sleek and small if you just want a basic tracker. The Inspire 2 now packs a touch-enabled button on each side of the case, which our reviewer found easier to press than the buttons on the Sense and Versa 3. Fitbit also upgraded the backlit OLED panel, though it’s not the most noticeable. It had to be pointed out during our time with the watch, and it can still be tough to see in broad daylight.

If you want a wearable that will last a while, the Inspire 2 is a solid choice. We were able to push it for about 10 days on a single charge, and Fitbit even addressed some of the charging issues from past years. Where the old charger barely stayed attached, the new one features a small pair of clasps that lock it to the device.

Don’t break the bank: The best cheap fitness trackers

Since you won’t get as many advanced metrics with the Inspire 2, it’s nice to know that the heart rate sensor packs a punch. It’s not the same PurePulse 2.0 sensor from the Sense and Versa 3, but we managed impressive results given the price of the wearable. Although the Inspire 2 took a few extra minutes to lock in like some of our higher-end fitness trackers, it managed to stay reasonably consistent with our reliable chest strap throughout testing.

As you might expect, the Inspire 2 only offers connected GPS rather than built-in tracking. This might be your deciding factor in the Inspire against a more powerful wearable like the Charge 5. If you just like to mount your phone to your bike and track your ride, then this should be perfect. The connected GPS feature also lets you track your workout intensity in the Fitbit app. It maps out your route with different heart rate zones to better understand how hard you’re training and where you exert the most effort.

What makes it stand out

  •  K.I.S.S: The Inspire 2 is a perfect example of Keep It Simple, Stupid. It covers the basics of fitness tracking but skips the fancier sensors and measurements in order to keep the cost low.
  • Renewed, not reinvented: Fitbit didn’t have to rebuild the Inspire. Instead, it offers a brighter display and an improved charger to make daily use easier.
  • Connected GPS: Opting for connected GPS instead of standalone doesn’t always work, but it makes sense on the Inspire 2. You’re more likely to use it as a fitness companion with your phone as opposed to a standalone fitness watch.

Fitbit Luxe: The most stylish fitness tracker

Fitbit Luxe
Fitbit Luxe
Attractive design • Good health tracking • Lightweight build
It's a good fitness tracker at an OK price.
The Fitbit luxe is a fashion-forward fitness tracker with the motivation to give your body and mind the healthy boost it deserves. A chic bracelet design, on-wrist tracking, and a one-month Fitbit Premium trial for new and returning premium users make the Luxe an enticing option.
$91.99 at Amazon
Save $37.96

The Fitbit Luxe is a little something different from the fitness tracking giant. It’s sized like the Inspire 2 and packs similar sensors, but the design is more refined like the Charge 5. The Luxe is your answer if you’re after a wearable to cover the basics that’s a little higher on style. Just be aware that style comes at a bit of a cost — the Luxe is more expensive than the Fitbit Charge 4 despite having fewer overall features.

For those who are still interested, the Fitbit Luxe is perhaps the best-looking band-style fitness tracker. We had plenty of good things to say in our review, starting with the stainless steel body. It has a bit more heft to it than some other Fitbit bodies, and it’s easy to dress up with other stainless steel or leather bands. The bands are, however, proprietary, so you won’t be able to repurpose options from other Fitbits or wearables. Fitbit added its sharp AMOLED panel to the Luxe and touch controls, which means you’ll have to swipe and tap your way through the menus.

As far as performance goes, we’ve established that the Luxe is built for the basics. It doesn’t have standalone GPS, though we did get it to connect to our Pixel 5 within a minute or two for most activities. We also saw distance and calorie burning metrics that were on par with our Garmin Fenix 6 Pro, even if the total number of steps varied a bit. Like its plain Inspire 2 sibling, the Luxe has a fairly accurate heart rate sensor. It’s the same PurePulse, and it generally followed the Fenix 6 Pro note for note.

Once you get past the basics of fitness, the Luxe is a good health tracker, too. It picked up blood oxygen level support in October 2021, which makes good use of the SpO2 monitor that previously sat dormant. We’ve got some slight gripes with the fact that Fitbit keeps launching incomplete products, but we do love a good feature drop. Fitbit’s menstrual cycle tracking is helpful, too, especially given that the Luxe is a female-focused tracker. Technically anyone can go for the fashionable wearable, but the jewelry inspiration is readily apparent.

Blood oxygen monitoring isn’t the only feature late to the party. Fitbit also introduced the Daily Readiness Score, which first appeared on the Charge 5. It gives you a better idea of what you should do for the day, somewhat like Garmin’s Body Battery. The DRS factors in your rest and recovery before recommending how much you have in the tank. We liked the feature during our time with the Luxe, but we wish it wasn’t locked behind Fitbit Premium.

What makes it stand out

  • Jewelry-inspired design: Anyone shopping for both form and function will appreciate the fashion-forward design of this accessory.
  • Sized like the Inspire, controlled like the Charge: The Luxe takes highlights from each of its siblings for a mashup that’s tailor made for niche users. It’s the perfect blend of power and portability.
  • Basic (in all the right ways): With this device, Fitbit doesn’t try to do too much. The Luxe delivers all the core stats without drowning users in extra details or data.

Fitbit Ace 3: The best pick for kids

Fitbit Ace 3
Fitbit Ace 3
In-app Parent and Kid Views • Hardy, colourful design • Family challenges
Need to get your young ones moving? The Fitbit Ace 3 is one of the best fully featured fitness trackers for kids. Eight-day battery life, sleep tracking, and a kid-friendly design are just a few reasons you should consider the Ace 3.
$55.99 at Amazon
Save $23.96

The Fitbit Ace 3 has the rare distinction of the only fitness tracker on this list that we haven’t reviewed. Not for lack of trying, we just couldn’t convince any of our children to write a few thousand words about it. While we don’t have the most in-depth thoughts to offer you, it’s probably best to think of the Ace 3 as a Fitbit Inspire 2 for kids. It has the same simple black and white display setup, but the Ace 3 offers a few different styles that are more kid-friendly and less business ready.

Even though it’s designed for a young world, the Fitbit Ace 3 still packs a grown-up experience. It has a kid-specific version of the Fitbit app, where kids can check their stats and badges in a protected setup. Safety is still an important factor, as parents will have to set up a family Fitbit account and approve each of their child’s connections. If your kid has a smartphone (which we can debate for hours), the Ace 3 can deliver notifications just like any other Fitbit.

As a kid-focused wearable, the Fitbit Ace 3 goes after a slightly different dataset. Yes, it covers sleep, steps, and active time with its eight-day battery life, but you won’t be able to watch your calories burned or use any metrics to measure weight loss. It also skips on GPS connectivity, though you can track different activities like trampolining — which is probably not something you’d use on a normal Fitbit too much.

Equip your kids: The best Fitbits for kids

We have to give Fitbit credit for thinking through just about every aspect of a fitness tracker for kids. Some of the Ace 3’s custom watch faces only animate when you’re moving around. You can change the face to match your kid’s favorite genre, like space or unicorns. There aren’t too many movie tie-ins, but there’s a special Minions edition if you’re not tired of those little yellow monsters yet.

Fitbit lists its Ace 3 for six or older kids, which feels like a reasonable range. It’s fun enough for little kids to feel like their parents with wearable tech but not so childish as to seem out of place for a slightly older kid. Overall, it’s tough to put another kid-focused fitness tracker above the Ace 3.

What makes it stand out

  • Kid-safe setup: The Fitbit Ace 3 requires a healthy level of parental engagement. Parents will have to create a family Fitbit account to approve connections and certain features within the Fitbit app.
  • Easy to clean: Kids are messy, but you can pop the Ace 3 out of its silicone band. From there, it’s easy enough to wipe down the band and the tracker or give it a quick dunk — it’s 5 ATM water-resistant, after all.
  • Great battery life: The Fitbit Ace 3 can last up to eight days on a single charge, which is great news for kids on the go. It means they can run, swim, or play all week and charge back up over dinner one night.

Why you should trust us & how we test

Android Authority has a long history with wearable devices, spanning back at least as far as the Pebble in 2013. Since then, we’ve reviewed hundreds of wearables and learned a lot along the way. Our team of dedicated health and fitness experts tests dozens of new wearables and fitness trackers every year, but only the very best make it onto recommendation lists like the one you are reading. How do we determine what’s worthy? When testing, we have two main focuses in mind: user experience and accuracy. To that end, we start by utilizing the device as a daily driver:

  • We wear the product 24/7 (except for charging time) to evaluate its day-to-day performance, capabilities, and comfort.
  • We note everything from strap materials and display brightness to navigation and battery life.
  • We tap into as many features as possible, leaving no stone unturned.
  • We set alarms, chat with voice assistants, fire off texts, follow breathing exercises, sweat through workouts, and much more.
  • We test sleep tracking accuracy and wear the watch to bed, comparing its data to other products well-regarded for their sleep analysis.
  • We test SpO2 sensors against other wearables or a pulse oximeter.
  • For heart rate monitoring, we equip chest straps to test the device’s accuracy and push the sensor through interval training workouts.
  • We also test GPS accuracy on outdoor runs and rides wearing the device, along with a notably accurate GPS device, to see how the review unit performs.
  • When possible, we strap on a comparable device from the current market to analyze how the review subject stands up to similarly-priced competition.
  • We dig into the companion app. We look to see how the data is organized and analyzed, and evaluate the ease of use.

You can trust that our experts put every device through its paces. Typically, our review period lasts about a week, but we can sometimes extend it to weeks or months for especially feature-packed devices. We also revisit watches and trackers regularly to ensure they still hold up over time.


The Fitbit Sense, Versa 3, Charge 5, Charge 4, and Ionic all have a built-in GPS.
