If you're unsure of which Fitbit to choose, keep in mind that the Fitbit range roughly divides into Fitness Trackers, which are 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 Fitness Trackers
- Fitbit Charge 4 – a safe bet for Fitbit's best fitness tracker
- Fitbit Inspire 2 – the best value Fitbit you can choose
- Fitbit Ace 2 – a fitness tracker aimed at kids
Best Fitbit Smartwatches
- Fitbit Sense – the top-of-the-line Fitbit smartwatch
- Fitbit Versa 3 – the best value smartwatch from Fitbit

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 4 – 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 – namely the Fitbit Sense and Fitbit Versa 3.
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 4
Best Overall Fitness Tracker
The Fitbit Charge 4 is the most powerful fitness tracker released by the popular company, and its specs show some notable improvements over previous models.
For one, the addition of built-in GPS is a big deal for many, particularly considering the smartphone GPS functionality has always been a bit spotty. The upgrade also features all-day calorie burn tracking, real-time heart rate zones, and Active Zone minutes – marking a substantial improvement to valuable features.
To make the Charge 4 even more impressive, the price hasn't gone up much, at only $149, so you can still keep your wallet intact. Admittedly, the Charge 4 isn't a massive upgrade from the Charge 3 outside of the additional tracking features and the built-in GPS. But if those are important to you, the price tag shouldn't dissuade you too much.
Fitbit Charge 4 Features
- All-day calorie burn monitor
- Built-in GPS
- Active Zone minutes
- 7-day battery life

Pros
- Built-in GPS
- Long battery life
- Water resistant up to 50 meters
Cons
- No music functionality
- Setup can be difficult

Fitbit Inspire 2
Best for fitness tracking on a budget
The Inspire 2 costs just $99, a great price for a brand new fitness tracker from a leading fitness company.
Still, despite the low cost, the Inspire 2 has some advanced features including 24/7 heart rate tracking, guided breathing functions, as well as some basic sleep tracking. It's also swim-proof and allows you to track how long you've been swimming for.
What's more, the Inspire 2 should give you up to a whopping ten days of battery life, meaning you'll be able to keep track of everything you do, all the time. Plus, the Inspire 2's slim design means that it shouldn't get in the way of your clothing.

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

Pros
- 24/7 heart rate tracking
- Guided breathing sessions
- Active zone minutes
- 10-day battery life
Cons
- No on-board GPS
- Small screen
Fitbit Sense
Best for Smartwatch Fans
The Fitbit Sense 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.
From a fitness standpoint, the Sense 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 Sense also comes with “female health tracking”, designed to help women learn more about their menstrual cycle, ovulation, and fertility. This is available to users aged 13+ in the US, and also comes with in-app advice from health professionals, health predictions, and related Fitbit Community groups.
The Sense also matches the latest Apple Watch and Samsung Galaxy Watches for advanced health features. It offers proper electrocardiogram readings and atrial fibrillation heart scans to help you can an eye on your respiratory wellbeing. The Sense will also help you understand and measure your stress levels, and even let you track your skin temperature.

Fitbit Versa 3
Best Affordable Smartwatch
The Versa 3 isn't quite as powerful as the Sense, losing out on some of the high-end health features while keeping all the fitness tracking smarts.
Despite costing $100 less than the Sense, the Versa 3 even looks similar, with the same 1.58-inch screen with rounded edges and a very slim profile. So really, it comes down to health tracking — do you need electrocardiogram readings? If so, get the Sense. If not, get the Versa 3.

- Personal coaching
- Fitbit Dashboard
- Female health tracking
- Guided breathing sessions
- Advanced fitness tracking

Fitbit Ace 2
Best 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.
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.

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

Pros
- Great for kids

Cons

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.
Additionally, the cheapest smartwatch on the list is the Fitbit Versa 2, the predecessor to the Versa 3. You'll pay a full $50 less than the new model but you'll lose built-in GPS and Fitbit's improved heart rate sensor, so choose wisely.
The Sense and Versa 3 are high-end smartwatches with a great range of features. The Inspire 2, on the other hand, is a slim fitness tracker which can be helpful if you're looking to up your daily exercise.
