Fitbit are the original and most famous activity trackers. They are one of the world’s leading products for wearable technologies, and claim to have sold more than 100 million products to more than 28 million users. The first Fitbit product, the Fitbit Classic, launched in 2009 and was more like a classic clip-on pedometer.
Since then, the company has expanded into a huge variety of trackers, smart watches, accessories, and even a bathroom scale. So how many types of Fitbits are there? Let’s find out!
Fitbit Trackers
The current line of Fitbit trackers are the:
Inspire
The Fitbit Inspire is a wristband tracker that features the following:
- All-day activity: steps, distance, active minutes, and calories burned
- Sleep tracking: silent alarms and bedtime reminders help track and improve your sleep
- Female health tracking: log your cycle, symptoms, and more
- Clock, timer, and stopwatch: the Inspire includes basic time and clock features you need during the day
- Automatic exercise recognition: the tracker automatically recognizes and records your physical activity
- Reminders to move: periodic prompts to get a few minutes of exercise when you’ve been sedentary for a while
- Digital connectivity: the Inspire will provide notification and alerts from your phone, so you don’t miss calendar reminders, incoming messages, or social media notifications
- Touchscreen display and customizable clock faces: a backlit OLED display responds to swiping and scrolling, and you can choose your clock face
- Battery life: up to 5 days of battery life
- Water resistance: the Inspire is water resistant to 50 meters, so you can wear it in the shower or the pool, and log swimming as exercise
Inspire HR
The Inspire HR has all of the above, along with active monitoring of your heart rate. The Inspire HR has all the features and capabilities of the Inspire, along with:
- Heart rate monitoring: the Inspire HR tracks your heart rate 24/7, giving you insight into your resting heart rate and more accurate calorie burn tracking
- Cardio fitness: by tracking your heart rate, the Inspire HR shows your active heart rate zones and cardio fitness levels
- Advanced sleep tracking: heart rate monitoring is able to capture your sleep stages and better improve your sleep quality
- Guided breathing: the Inspire HR has personalized guided breathing sessions based on your current heart rate
- More detailed exercise tracking: the Inspire HR has goal-based exercise modes, and connects with your phone’s GPS for more accurate information about location and distance
Ace 2
The Fitbit Ace 2 is designed for kids, with a smaller wristband, simplified interface, and parental controls. The Ace 2 has many of the same features as the Inspire, including:
- Activity and sleep tracking
- Water resistance to 50 meters
- Up to 5 days battery life
- Customizable clock face
- It also has kid-friendly activity challenges and celebrations when a goal is reached, and parental controls that allow parents to see their child’s activities and monitor their social activity on the Fitbit App.
Charge 4
The Fitbit Charge 4 has active heart rate monitoring, so it has all the features and capabilities of the Inspire HR. It also includes more capabilities, like:
- Built-in GPS: instead of relying on your phone’s GPS, the Charge 4 has GPS capabilities, so you can track distance and location and see your workout maps in the Fitbit App
- Spotify integration: the Charge 4 allows you to browse and play your favorite Spotify playlists and podcasts
- Fitbit Pay: when your payment information is added to the Fitbit App, you can use the tap-and-pay features of the Charge 4
- Longer battery life: the Charge 4 can go up to 7 days without a recharge.

Fitbit Smartwatches
Fitbit also makes a line of smart watches. Current Fitbit smart watch models include:
Ionic
The Fitbit Ionic monitors heart rate and has advanced digital integrations, so it has all the capabilities and features of the Charge 4 (although it only has a 5 day battery life and doesn’t track female health stats), along with many of the features you expect from a smart watch, including:
- App integration: the Ionic is compatible with a wide range of popular third party apps for sports, weather, and other capabilities
- Quick replies: when the Ionic is paired with an Android device, you can send short text message replies to incoming messages and notifications
- More music: the Ionic stores and plays 300+ songs, and allows you to download and play Pandora or Deezer playlists
- Bluetooth headphones: the Ionic connects with your wireless headphones
- More rugged design: as a watch, the Ionic has more options in accessories, more rugged glass and premium materials, and higher resolution on the touchscreen.
Versa 2
The Versa 2 has virtually the same features as the Ionic, with just a few differences:
- No GPS: the Versa 2 does not have built-in GPS and needs to be paired with your phone for GPS data
- Longer battery life: the Versa 2 has a 6 day battery life, vs. the 5 days of the Ionic
- Voice replies: With the Versa 2 and an Android phone, you can use your voice to send short messages in response to notifications
- Always-on and sleep display modes: the Versa 2 has an always-on display option that lets you read your Fitbit at a glance, or mute notifications and alerts for sleep.
Versa Lite
As you might expect, the Versa Lite does almost everything the Versa 2 does, without:
- On-screen workouts
- Voice replies
- Spotify controls
- Fitbit Pay
- Always-on display mode
