With dozens of options, it’s not always easy to figure out the right fitness tracker. Knowing the specific brand you are interested in helps. If you’re on this page, the odds are that brand is Fitbit. The company makes a full suite of approachable wearables that will work for most people, including Google Pixel Watch line. Thanks to the influence of Google, Fitbit also has some exciting new features in store for later this year, including a Fitbit AI health chatbot for deeper analysis and insights.

Fitbit Charge 6: The best band-style tracker, period

Fitbit Charge 6Fitbit Charge 6
AA Recommended
Fitbit Charge 6
Useful physical button • Updated heart rate sensor • All sport modes now on device
MSRP: $159.99
The Fitbit Charge 6 is the company's 2023 top-of-the-line fitness tracker
When it comes to fitness trackers, the Fitbit Charge 6 is now the best product in the company's portfolio. To get anything better, you'd need to jump up to the Sense 2, which is more like a smartwatch. The Charge 6 has a full-color display, 40 exercise modes, and the most advanced heart-rate tracker Fitbit offers.

There’s no doubt about it — the Charge is the classic Fitbit. You’ll probably think of this band-style tracker if someone mentions the brand. The lineup has been around since the company began in 2014, and it hasn’t waned in popularity. The Fitbit Charge 6 is the most recent iteration of the lineup, delivering powerful tools and upgraded specs.

We were thrilled during our Charge 5 review when Fitbit introduced a 1.04-inch full-color AMOLED panel to the lineup which made a return appearance on the Charge 6. We found the band extremely comfortable during our Charge 6 review and loved the return of a physical button for easier navigation. The newer device also offers all the same health-tracking sensors. This means detailed sleep tracking, SpO2 monitoring, heart rate tracking, AFib monitoring, an ECG sensor, an EDA sensor, and an accelerometer. However, the Charge 6 uses AI and machine learning to provide advanced heart-rate monitoring and added workout features. During our review, the heart rate monitor kept up with much pricier devices.

Highlights added to the lineup via the device include additional sports profiles. The Charge 6 ups the offered workout routines from 20 to 40 while making all workouts available on the wrist simultaneously. This is a massive improvement in terms of streamlining the user experience. The device also syncs with gym equipment, allowing users to share heart rate data with compatible machines such as a Peloton bike. Meanwhile, the Fitbit companion app remains user-friendly for accessing and digesting tracked data. We aren’t thrilled with the latest app redesign, but it is still a very approachable platform for anyone new to tracking.

On the smart feature front, the tracker packs Google Maps so users can access turn-by-turn directions right on their wrists. The app requires a connection to a smartphone where directions must be initiated, but the notifications will appear on the tracker itself. The Fitbit Charge 6 also adds Google Pay support for contactless payments and YouTube Music controls. These additions round out the device and make it more competitive among smartwatches. Notably, the Fitbit Charge 6 is not compatible with legacy Fitbit accounts. Users are required to transfer their Fitbit account to a new Google account.

Unfortunately, no device is perfect. The Charge 6’s weakness lies in its inconsistent GPS tracking. Our reviewer had difficulty attaining accurate routes during outdoor runs and cycles due to the placement of the GPS antenna within the device. Luckily, users can always swap to connected GPS as needed.

Despite the added features and upgraded experience of the Fitbit Charge 6, it is also priced lower than its predecessor’s original launch price. Shoppers can grab the Fitbit tracker for $159.

What makes it stand out

  • Equipment compatibility: The update to include compatibility with popular workout machines makes the Charge 6 more versatile for users committed to their fitness routines.
  • Accurate sensors: Fitbit’s Charge line continues to boast accurate heart rate and GPS sensors, offering active users reliable data.
  • A tracker with NFC: Unlike the Inspire 3, below, the Charge 6 offers support for digital payments so you can make purchases on the go.

Best of the rest: 7 other Fitbit trackers and smartwatches worth considering

Although we recommend the Fitbit Charge 6 as the classic choice from Fitbit, plenty more watch- and band-style options are available. Here’s the best of the rest:

Watch-style Fitbits

  • Google Pixel Watch 2: Though a slightly unconventional choice that not everyone would consider a true Fitbit, the Google Pixel Watch line offers a unique experience. The second-generation Wear OS smartwatch boasts the best of Google plus Fitbit integration.
  • Versa 3: The Versa 3 offers the best value for its price tag among watch-style Fitbit trackers. We like this model better than the newer Versa 4, though we’re disappointed with many changes Fitbit has made to the line.
  • Sense: Compared to the Versa 3, 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.

Band-style Fitbits

  • Inspire 3: Fitbit’s Inspire 3 is a great value if you want to cover the basics of fitness tracking. It packs around-the-clock heart rate monitoring, and it’s remarkably lightweight. It’s a good intro to activity tracking.
  • Luxe: Fitness tracking and fashion really can go hand in hand. The Luxe features a rounded, jewelry-inspired design and a host of bracelet and strap options to match many 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 comfortably all day and build healthy habits.

Google Pixel Watch 2: The best nonconventional Fitbit device

Google Pixel Watch 2Google Pixel Watch 2
Google Pixel Watch 2
Runs a snappy Wear OS 4 • Added and upgraded advanced health sensors • Fast charging alleviates battery woes
MSRP: $349.99
Wear OS 4, advanced health sensors, and upgraded training features elevate the Pixel Watch 2
The Google Pixel Watch 2 retains the first model's successful features and refines several of the original's shortcomings. Added sensors, upgraded training tools, and a few key changes suggest a more finished product. Google's Wear OS 4 runs flawlessly, while advanced health tools from Fitbit join the lineup.

Google’s in-house smartwatch line might not seem to belong on this list. However, with thorough Fitbit integration, the Pixel Watch 2 is very much a Fitbit device. It’s even sold on the company’s website. In addition to offering Fitbit’s most advanced sensors, what really makes the device stand out compared to the Sense 2, for example, is that it also features an unfiltered Wear OS experience. It also tweaks many of the first generation’s shortcomings for a better overall device.

The Google Pixel Watch 2 houses Fitbit features in three apps. With Fitbit Exercise, users can record workouts, view exercise metrics, and monitor on-screen heart rate zones during activity. The Fitbit Today app lets users check their steps, calories, sleep data, and more. Finally, Pixel Watch 2 users can take on-demand readings and monitor their heart health with the Fitbit ECG app. Since the watch syncs to your Fitbit account, you can review all your tracked stats in the Fitbit app on your paired phone. During our review, we loved having a seamless Fitbit experience on an otherwise Wear OS device.

Beyond Fitbit, the Pixel Watch 2 has many other features to like. The device’s build offers a modern, sleek look nearly identical to last year’s model and plenty comfortable for all-day wear. The slightly larger rotating crown makes scrolling through menus a breeze. Thanks to the device’s powerful processor, its Wear OS 4 software ran fast and smoothly during our review period. Users can also personalize the watch with many native watch faces plus thousands more options through the Google Play Store.

In general, access to the Google Play Store is one of the features that makes this pick a strong candidate among Fitbit devices. Users can add virtually any tool needed with third-party Pixel Watch apps just a few taps away. We loved listening to Spotify while earning Activity Zone Minutes and following hard workouts with content from Calm. Native Google apps also round out the experience, including Google Maps, Google Home, and Google Assistant. Overall, it’s a well-rounded smartwatch worth Android users’ consideration, not just Fitbit fans.

What makes it stand out

  • Google, Google, and more Google: Simply put, no other device in this list offers the same level of smartwatch experience as the Google Pixel Watch 2. This is the top pick for access to many third-party apps in the Google Play Store and the best of Google’s tools.
  • Sleek design: The Pixel Watch 2 is nothing if not a sleek, modern wearable. The domed glass display and integrated straps offer a clean look that can be customized with plenty of replacement bands.
  • Fitbit integration on Wear OS device: If your heart is set on Fitbit’s health and fitness tracking suite but you also want a Wear OS device, the Google Pixel Watch 2 has you covered.

Fitbit Versa 3: The best value watch-style Fitbit device

Fitbit Versa 3Fitbit Versa 3
Fitbit Versa 3
Decent battery life • Accurate health tracking • Built-in GPS
MSRP: $229.95
The best value Fitbit smartwatch
The Fitbit Versa 3 carries all the smart features you could want on a mid-range smartwatch, including Google Assistant support, voice replies, and reliable health tracking. It's effectively a Fitbit Sense without the pricier specialized sensors.

The Fitbit Versa 3 isn’t the flagship watch in the brand’s lineup — that honor goes to the Sense 2, which we will return to a bit later in this guide. There is also a newer Versa 4, but we believe the Versa 3 is the best value, true Fitbit smartwatch you can buy. We tested the newer model and found it drops key features that make its predecessor such a valuable device.

We love that the Versa 3 is sleek and comfortable despite being larger than the Charge 6. The only features that separate the Versa 3 from its more expensive Sense siblings are the lack of ECG, EDA, and skin temperature sensors. Meanwhile, unlike most smartwatches (including the Pixel Watch 2), the Versa 3 has exceptional battery life. We consistently saw about three and a half days of battery life in our testing, including using sensors like the heart rate monitor and GPS.

Regarding activity monitoring, the Versa 3 lives up to the family name. We saw accurate results in step counting, sleep tracking, and most other basics. It also boasts an altimeter, a feature that Fitbit ditched in its Charge 5 and 6. Finally, the built-in GPS on the Versa 3 worked well throughout our testing and remained accurate even in areas with a weak signal.

The Fitbit Versa 3 is a fitness watch 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 offers. It’s not perfect by any means, and you’ll still get better results with a chest strap, but it handled our tests pretty well. The Versa 3 isn’t the fastest regarding rapid heart rate changes, and it seemed worse at the start of our testing. Over time, the watch improved its readings, though it didn’t always lock on as fast as the Versa 2.

Sleep tracking is another one of the Versa 3’s key selling points. Like the Pixel Watch 2, the watch tracks light, deep, and REM sleep. It also offers snore and noise detection 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 Withings ScanWatch, one of our favorites for sleep tracking. Plus, Fitbit offers Sleep Profile, a program that analyzes users’ sleep quality monthly, offering deeper insights and guidance.

Finally, the Fitbit Versa 3 is a smartwatch, too. In addition to ample display space, one of our favorite features is the ability to swap out the watch face whenever we want. The device doesn’t have a massive app store, but it does cover the basics like Starbucks. Unfortunately, Fitbit continues to strip down the smart features on these smartwatches, and as of June 2024, users won’t be able to download additional apps. You can, however, choose Alexa or Google Assistant as your preferred voice assistant on the Versa 3 and place calls right from your wrist. The Versa 4, meanwhile, does not offer support for Google Assistant.

Overall, the Fitbit Versa 3 is well-balanced between fitness tracking and everyday life and won’t hurt your wallet too much. That said, Fitbit’s smartwatches are bare-bones compared to other leading smartwatches, like the Pixel Watch 2 above or the Apple Watch, for example. If you expect a fully-featured smartwatch, you’ll want to shop elsewhere.

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 Versa 3.
  • 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.

Fitbit Sense: The best pick for health tracking

Fitbit SenseFitbit Sense
Fitbit Sense
Premium design • Accurate sensors • 6-day battery life
MSRP: $299.95
One of the most advanced health watches.
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 Sense 2. The original Sense is, without a doubt, the data junkie’s Fitbit. It’s not perfect — the sensors could use a little refining — but it offers more tracking stats than you can shake a stick at. Before we get ahead of ourselves, though, a Fitbit Sense 2 is also available. We reviewed the newer device, and frankly, we weren’t impressed. Like the Versa 4 mentioned above, the Sense 2 dropped key features that made this lineup impressive, including third-party app support. We’re sticking with the older model as the better value buy for now.

We’ll dig into the Sense’s sensors first, as they will likely be your deciding factor between the Sense and the Versa 3. Fitbit offers three helpful options: an EDA, a medically certified ECG, and a skin temperature sensor. There’s a lot of data 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 to measure how electrodermal activity influences your mental state and, therefore, your stress level. The process takes about two minutes to build per reading, but some of the data lacks explanation. For example, we experienced six EDA responses in one of our tests but got no indication of whether that was 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 sensors, the Fitbit Sense is king in 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 line’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, though 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. Meanwhile, the newer Sense 2 only offers Alexa. You can also add a small library of apps. Finally, the Fitbit Sense also delivered around five days of battery life in our testing — a solid mark given its bevy of sensors.

What makes it stand out

  • Unreal battery life: Fitbit advertises six days of battery life, and we regularly achieve 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 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 Inspire 3: The best cheap Fitbit

Fitbit Inspire 3Fitbit Inspire 3
AA Editors Choice
Fitbit Inspire 3
Excellent display • Long-lasting battery • Detailed and fun sleep tracking
MSRP: $99.95
Fitbit's entry-level device tracks all the basics, from sleep to SpO2
The slim, comfotrable Fitbit Inspire 3 packs accurate sensors and a bright, colorful display. It also boasts a nearly ten-day battery life so you can track activity by day and monitor sleep overnight, without worrying about daily charging. Plus, each Inspire 3 comes with six free months of Fitbit Premium access.

So far, our top Fitbit picks have been about getting the most powerful fitness tracking experience. Sometimes, however, it’s better to keep things simple. At just under $100, the Fitbit Inspire 3 is the best pick for anyone who casually wants to track their activity with a reliable device. We consider it one of the best cheap fitness trackers available.

Compared to the last generation, the Inspire 3 offers a colorful display that users can personalize with watch faces in the Fitbit app. Fitbit also added an ambient light sensor so the screen’s brightness will automatically adjust based on the lighting in your environment. This upgraded screen also rests on a revamped case shape with a longer, thinner profile. The result is a sleek device you can even dress up with various fashionable bands.

Where the device excels is its exceptional battery life. If you want a wearable that will last a while, the Inspire 3 is a great choice. After nearly 8 days of heavy use, we still had battery life left in the tank. That means tracking stats and sleep for over a week without stressing about when to charge up. Compared to leading fitness trackers and smartwatches, that is a huge benefit.

The Fitbit Inspire 3 automatically tracks all your basic health and fitness stats plus offers 24/7 heart rate monitoring. Fitbit will even notify you of heart rate irregularities that may be signs of atrial fibrillation (AFib). If your resting rate is especially high or low at any point, Fitbit will alert you of those anomalies as well. We found the heart rate sensor consistently on target throughout our review. We were also happy to find on-wrist SpO2 monitoring.

As you might expect, the Inspire 3 only offers connected GPS rather than built-in tracking. This might be your deciding factor when comparing the Inspire against a more powerful wearable like the Charge 6.

What makes it stand out

  •  K.I.S.S: The Inspire 3 perfectly exemplifies Keep It Simple, Stupid. It covers the basics of fitness tracking but skips the fancier sensors and measurements to keep the cost low.
  • Renewed, not reinvented: Fitbit didn’t have to rebuild the Inspire. Instead, it offers a better display with optional always-on and key improvements to health monitoring.
  • Great value: Any entry-level fitness tracker is a step in the right direction for pursuing healthy habits. However, an entry-level device that also opens the door to Fitbit’s ecosystem is an even greater value buy.

Fitbit Luxe: The most stylish fitness tracker

Fitbit LuxeFitbit Luxe
Fitbit Luxe
Attractive design • Good health tracking • Lightweight build
MSRP: $129.95
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.

The Fitbit Luxe is a little something different from the fitness tracking giant. It’s sized like the Inspire line and packs similar sensors, but the design is more refined, like the Charge 6. The Luxe is the answer if you’re after a wearable that covers the basics and is a little higher on style. Just be aware that style comes at a cost — the Luxe is more expensive than the Fitbit Charge 4 despite having fewer overall features.

For those 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 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, meaning you’ll have to swipe and tap through the menus.

Regarding performance, we’ve established that the Luxe is built for the basics. It doesn’t have a 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 burn metrics on par with our Garmin Fenix 6 Pro, even if the total number of steps varied slightly. Like its plain Inspire 2 sibling, the Luxe has a fairly accurate heart rate sensor. It’s the same PurePulse and generally follows the Fenix 6 Pro note for note.

Once you get past the basics of fitness, the Luxe is a good health tracker. It also picked up blood oxygen level support in October 2021, using the previously dormant SpO2 monitor. 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, 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 weren’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): Fitbit doesn’t try to do too much with this device. Instead, 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 3Fitbit Ace 3
Fitbit Ace 3
In-app Parent and Kid Views • Hardy, colourful design • Family challenges
MSRP: $63.96
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.

The Fitbit Ace 3 has the rare distinction of being the only fitness tracker on this list that we haven’t reviewed. Not for lack of trying, we couldn’t convince our children to write a few thousand words about it. While we don’t have the most in-depth thoughts, 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. However, the Ace 3 offers a few 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 important, as parents must set up a family Fitbit account and approve each of their child’s connections. The Ace 3 can deliver notifications like any other Fitbit if your kid has a smartphone.

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

We must give Fitbit credit for thinking through 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’s even 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. Meanwhile, it’s not so childish as to seem out of place for a slightly older kid. Overall, putting another kid-focused fitness tracker above the Ace 3 is tough. For options for older children, check out our guide to the best Fitbits for kids.

What makes it stand out

  • Kid-safe setup: The Fitbit Ace 3 requires a healthy level of parental engagement. Parents must 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 to wipe down the band and the tracker or give it a quick dunk.
  • Great battery life: The Fitbit Ace 3 can last up to eight days on a single charge. This 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 at least as far as the Pebble in 2013. Since then, we’ve reviewed hundreds of wearables and learned a lot. Our dedicated health and fitness experts test dozens of new wearables and fitness trackers yearly. Only the 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: 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. However, we can sometimes extend it to weeks or months for especially feature-packed devices. We also regularly revisit watches and trackers to ensure they hold up over time.


The Fitbit Sense, Sense 2, Versa 3, Versa 4, Google Pixel Watch 2, Charge 6, Charge 5, Charge 4, and Ionic all have a built-in GPS.

At the time of this writing, no Fitbit product offers any fall detection, emergency, or SOS features.

No device is truly waterproof, but all recent Fitbit devices are water-resistant to 50 meters (5ATM), including those listed above.

Fitbit also sells the Fitbit Aria Air, a smart scale compatible with the Fitbit app that can track your weight and BMI trends. Additionally, the company sells extra charging cables and alternative straps for all its devices.

Yes, you can use a Fitbit smartwatch or tracker for weight loss. They feature exercise monitoring for a bevy of activities and a food consumption and calorie intake log.

Fitbit has several great fitness trackers and smartwatches to shop. We consider the Pixel Watch 2 the best Fitbit smartwatch for women and recommend the Charge 6 for anyone looking for a smaller form factor.

We consider the Charge 6 the best Fitbit for seniors.
