  • Best overall fitness tracker: Fitbit Charge 3 or Fitbit Inspire HR – it's a close run thing with these two, which have virtually all the features you'd need. The Inspire HR is a little newer, and a little cheaper, though the Charge 3 has a bigger battery
  • Best overall smartwatch: Fitbit Versa – though the Ionic has a few extra tricks, the Versa is great value
  • Best cheap Fitbit: Fitbit Inspire – at $69, this 2019 model is a steal. The main thing it's missing is heart-rate tracking

If you're unsure of which Fitbit to choose, keep in mind that the Fitbit range roughly divides into Fitness Trackers (activity monitors designed for tracking steps or sports), and Smartwatches, which do all of the above, but have deeper features thanks to their larger screens. A smartwatch will let you check your emails or text messages, for example, while a fitness tracker typically has a small screen that's fine for basic notifications only.

Best Fitbit Activity Trackers

If you're looking for a device primarily to track your steps, running or other exercise, and aren't too fussed about reading text messages on the screen, smartwatch-style, then the models below are the best Fitbits to go for.

Leading the pack is the Fitbit Charge 3 – this is the newest model in the range, and packs in some of the best features. It's even water-resistant to 50 meters, so it's perfect for the beach or pool. However, if you're looking for a more affordable option, you might want to go with the Inspire HR, which is filled with nifty features at a lower price.

Best Fitbit Smartwatches

Though Fitbit is best known for its fitness trackers, as with the models above, it produces a couple of good quality smartwatches, too – the Fitbit Ionic and Fitbit Versa.

What's the difference between a smartwatch and a fitness tracker? Good question. Both will track your steps, your sleep, and usually your heart rate. But a smartwatch has a larger screen and better integration with your smartphone, letting you read messages and emails and change the music that's playing through your phone.

The downside? Smartwatches are a bit chunkier on your wrist, compared to a slim fitness tracker.

Fitbit Charge 3

Fitbit Charge 3Best for Busy Fitness Buffs

The Fitbit Charge 3 has been dubbed Fitbit's “most advanced tracker yet”. In addition to tracking heart rate, sleep cycles, calories burned, and all the other fitness tracker standards, the Charge 3 will send calendar reminders and call notifications, so you can stay connected in and out of the gym. It's basically a smartwatch in fitness tracker clothing. Plus, it's essentially waterproof (water resistant up to 50 meters), which never hurts when you're shelling out a few extra bucks. Features include:

  • 24/7 heart rate monitor
  • Goal-based exercises
  • Sleep tracking with stages
  • 7-day battery life

As one of the newest devices in the Fitbit fitness tracker lineup, the Charge 3 is understandable a bit more expensive than a lot of the devices on this list. But with all these features and functionalities for staying healthy, it's certainly worth the extra cost.

For more on the Charge 3, see our full roundup of its features


  • Water resistant to 50m
  • Built-in smartwatch features
  • Long battery life


  • No on-board GPS
  • No pressable buttons

Fitbit Inspire

Fitbit InspireBest Affordable Fitness Tracker

The Fitbit catalog keeps on growing, and this 2019 model combines the fitness tracker company's latest innovative technology with an affordable price point. This gives everyone the chance to make their health a priority. The Fitbit Inspire may be a value-model, but it doesn't short-change you on the features you need to track your activity. The only thing missing is a heart rate monitor – see the Inspire HR model, below, if you're after that benefit. The Fitbit Inspire's features include:

  • All day activity tracker
  • All day calorie burn tracker
  • Food logging
  • Automatic exercise recognition
  • 5-day battery life

At only $69.95, the Fitbit Inspire is easily one of the most affordable and robust fitness trackers you can buy. Plus, with the comfortable band, slim body, and a wide range of interchangeable accessories, you'll be able to find the perfect fit for your fitness needs.


  • OLED display
  • Water resistant up to 50m
  • Solid battery life


  • No heart rate monitor
  • Basic sleep tracker

Fitbit Inspire HR

Fitbit Inspire HRBest for Serious Fitness Trackers on a Budget

The basic Inspire (above) is a great affordable option when it comes to fitness trackers, but it's lacking a number of crucial features that a serious health nut is going to miss. Fortunately, the Inspire HR is only slightly more expensive, and it adds a wide range of additional features that will take your health adventure to the next level, including:

  • 24/7 heart rate monitor
  • Thorough sleep tracker
  • Guided breathing exercises
  • 5-day battery life

At only $99.99, the Fitbit Inspire HR provides a reasonably priced device that comes with all the bells and whistles you'd need as a serious fitness buff. These added features are typically found in very expensive devices, so getting them for less than $100 is real bargain.


  • OLED display
  • 15 goal-based exercise modes
  • Affordable


  • No on-board GPS

Fitbit Ionic

Fitbit IonicBest for Smartwatch Fans

The Fitbit Ionic isn't a fitness tracker disguised as a smartwatch: it's just a straight up smartwatch. As the most expensive model on this list, that should have been expected. It comes with a wide range of fitness tracker features, as well as a few bells and whistles you can find on popular smartwatches. These include:

  • Music storage
  • Bluetooth headphone compatibility
  • Wallet-free payments
  • Access to popular mobile apps
  • Mobile notifications
  • Quick reply functionality

From a fitness standpoint, the Ionic matches the rest of the lineup and then some, tracking sleep stages, cardio fitness level, and heart rate. It has built-in GPS, is water-resistant, and provides personal coaching for a little extra inspiration. The Ionic also comes with “female health tracking”, designed to help women learn more about their menstrual cycle, ovulation and fertility. This is available to users age 13+ in the US, and also comes with in-app advice from health professionals, health predictions and related Fitbit Community groups.


  • Outright smartwatch functionality
  • Water-resistant
  • 4-day battery


  • Expensive
  • Bulky design

Fitbit Versa 2

fitbit versa 2Best Affordable Smartwatch

The Fitbit Versa 2 is a more affordable, more popular version of the Ionic, and for good reason. Between the sleeker design, lighter feel, and smaller price tag, it's no wonder the Versa has become the go-to smartwatch for Fitbit fans. Features include:

  • Personal coaching
  • Fitbit Dashboard
  • Female health tracking
  • Guided breathing sessions

The Versa 2 also comes with common smartwatch functionalities – such as wallet-less payments, call and text notifications, and access to popular apps – while reviews have insisted the device has a faster interface than that of the Ionic. It doesn't have the built-in GPS of its more expensive counterpart, though, which is worth considering when deciding between the two.

Compared to the original Versa smartwatch, the Versa 2 gets some welcome (if not game-changing upgrades). The 1.34-inch LCD screen on the original is replaced by a 1.6-inch AMOLED display — making the display easier to see in bright sunlight. It also has a larger battery and redesigned software. It might not be worth upgrading, but it's definitely a better option to buy a new Versa 2, rather than a reduced-price Versa.


  • Stylish
  • Less expensive than most smartwatches
  • 4-day battery life


  • No GPS

Fitbit Versa Lite

Fitbit Versa LiteCheap, But Missing Some Smartwatch Features

There are three smartwatches on this list, and this last one is the cheapest. It's a more affordable version of the Versa 2, above. However, for the price cut, you end up missing a few key features. These include on-screen workouts, music storage, and an all-day activity tracker. So, what features does it have?

  • Heart rate tracking
  • Smartphone notifications
  • Sleep tracking with stages
  • Guided breathing sessions
  • 4+ day battery life

The Versa Lite is a full $40 less than the Fitbit Versa 2, at only $159.95, making it a very competitively priced smartwatch option. Plus, considering it's only missing a few luxury features, you'd be hard-pressed to find a more affordable smartwatch option. After al, you may not need music stored on your watch to go along with your workout, given you'll likely have your smartphone nearby.


  • Stylish and lightweight
  • Affordable
  • 4+ day battery life


  • No GPS
  • No music storage

Fitbit Alta HR

Fitbit Alt HRBest Great Value Tracker

Though it's more limited than a smartwatch model, the Fitbit Alta HR is one of the best standalone fitness trackers out there. As Fitbit's slimmest device to feature a heart monitor, you'll be able to work out without feeling like you have an annoying growth on your wrist. Plus, with the PurePulse heart monitor, you'll be able to gain a fuller understanding of your own health. Other fitness tracking features include:

  • Accurate tracking for calories burned
  • Heart rate zones and trends
  • Automatic exercise recognition
  • Advanced sleep tracking reports

We have to admit that the Alta HR actually does have some smartwatch functionality, similar to the chunkier Fitbit Charge 3, in that it provides call, text, and calendar alerts. But that won't get in the way of your workout too much. The Alta HR is one of the more expensive fitness trackers on this list, but with all these features, it's worth the extra pennies.


  • Advanced fitness tracking features
  • Very slim


  • A bit pricey
  • Mainly limited to fitness
  • Hard to read screen in the sun

Fitbit Flex 2

Best for Basic Fitness Tracking

If you're looking for a classic fitness tracker without all the fluff, you've found it. The Flex 2 brings the classic, screen-less Fitbit look into the modern age with a minimalist design built for your lifestyle. Despite being the most affordable fitness tracker on the list, the Flex 2 still comes with a lot of handy features, including:

  • Automatic exercise recognition and sleep tracking
  • All-day activity tracking
  • Silent alarm
  • Call and text notifications
  • 5-day battery life

And in addition to being swim and shower proof, the Flex 2's minuscule tracker (weighing less than an ounce) is easily removable from the band, so you can put it in bangles, pendants, or other interchangeable accessories (also provided by Fitbit).


  • Classic, minimalist look
  • Lots of accessories


  • Very small tracker; easy to lose
  • No display

Fitbit Ace 2

fitbit ace 2Best for Kids

If your kids want to get in on the active lifestyle fun, the Fitbit Ace 2 can help. This fitness tracker is specifically designed for children to track their exercise, inspire them to be more active, and reward them for meeting their fitness goals. The durable design, combined with the fun, changeable bands, make the Ace the perfect device to get your child interested in something other than sitting on the couch. Features include:

  • Activity tracker
  • Achievement celebrations and badges
  • Fun, customizable clock faces
  • Connected family app
  • Competition functions with friends
  • Bedtime reminders

Between the serious fitness tracking features and the fun flourishes, the Ace 2 is the perfect solution for inspiring kids to get out and be active. And, considering the CDC recommends kids get at least 60 minutes of active play per day, it might be a good idea to grab this fitness tracker as soon as possible.


  • Great for kids
  • Customizable bands and watch faces
  • Designed to get them active


  • Smartphone notifications might be an issue for some parents
  • Obviously limited functionality compared to other models

Fitbit Zip

Fitbit ZipBest for People Who Hate Watches

Not everyone likes the feeling of a fitness tracker on their wrist, which makes the Fitbit Zip the perfect alternative. This handy fitness tracker can be clipped to your shirt, your pants, your sports bra, or pretty much anywhere during the day without getting in your way. Features include:

  • All day activity tracking
  • Wireless syncing
  • Daily stats
  • 6-month battery life

Obviously, as it's not attached to your wrist, the Zip is missing some key functionality. But as you can see, it still provides some basic features for improving your active lifestyle. If you're looking to try out a Fitbit before spending a bundle, the Zip is one of the least expensive devices out there, so get on it!


  • Very long battery life
  • Inconspicuous and unobtrusive


  • Minimal functionality
  • Few features

Frequently Asked Questions

Which is the best Fitbit to buy?

In our opinion, the best Fitbit you can buy is a tie between the Fitbit Charge 3 and the Fitbit Inspire HR. They both come in at reasonable prices, with plenty of features, and sizable battery lives. More specifically, the Inspire HR has a more modern design and has a few more features, while the Charge 3 has a longer battery life. Either way, you're getting a great fitness tracker at a good price.

Which Fitbit is the most accurate?

All Fitbit devices run on the same app, so most of them are quite accurate and the difference in accuracy is pretty minimal from fitness tracker to fitness tracker. However, some Fitbit devices measure things that other don't. The Charge 3, Inspire HR, and all Fitbit smartwatches, for example, feature a heart monitor, whereas the Fitbit Inspire does not. Make sure to consider these features when it comes to purchasing a fitness tracker.

What's the best Fitbit for women?

In our opinion, the Fitbit Alta HR is the best fitness tracker for women. It's lightweight, slim, and affordable, so it won't be too bulky when you're working out. Despite the small frame, it still comes with a stunning screen for smartphone notifications. Alternatively, if you're looking for a fitness tracker that isn't attach to your wrist, the Fitbit Zip is small enough to fit in a purse or clip to an outfit and accurate enough to effectively track steps and other exercises.

What is the cheapest Fitbit?

Outside of the Fitbit Zip, which is not a wrist-mounted fitness tracker and costs only $59, the Fitbit Inspire and Fitbit Ace 2 are the cheapest available devices at $69. The Fitbit Inspire is a previous iteration of the Inspire HR, and lacks some of the more modern features. The Ace 2 is the fitness tracker designed for kids, so you probably don't want to pinch pennies there.

Additionally, the cheapest smartwatch on the list is the Fitbit Versa Lite, a budget version of the Fitbit Versa smartwatch. You'll pay a full $40 less than the other models (only $149), but you'll lose music storage and all-day workout tracking, so choose wisely.

What's the newest Fitbit for 2019?

The newest device for 2019 is the Fitbit Versa 2, a hi-tech smartwatch with fitness tracking features built-in. It's a bit slimmer, lighter, and cheaper than former models, and comes with personal coaching, guided breathing sessions, and female health tracking features. You can also play Spotify playlists directly from your wrist, but you'll naturally need a subscription to do so.

Is it worth getting a Fitbit?

If you're a fitness buff that thoroughly enjoys the input of tracking apps, then getting a Fitbit is absolutely worth it. While other smartwatch makers can pack a little more punch, Fitbit still boasts some stellar fitness features that pair well with the mobile app. If, however, you're just looking to tech yourself out with some wearables, there are other options that might be a better fit.

What's better, a Fitbit or Apple Watch?

In all honesty, the Apple Watch is a better overall product compared to Fitbit smartwatches and fitness trackers. It offers more everyday features, a sleeker design, and better communication with the rest of your tech. Yes, they're decidedly more expensive, but an Apple Watch is nothing if not a solid value for the money.

Again, fitness buffs should still lean towards Fitbit, because of the specifically built-in features aimed at fitness tracking, but overall, the Apple Watch is a better product with a smoother interface that, particularly for iPhone users, just makes more sense.
