Fitbit Comparison: Which one is right for you?

Fitbit has a wide variety of watches and fitness trackers for many price ranges. This can make it hard to decide which one is best for your needs, so we decided to review 4 of the most popular Fitbits. Scroll down to see a comparison chart, or check out our 12 favorite fitness trackers here.

Fitbit Charge 3

The Fitbit Charge 3 is an overall great fitness tracker. It has a broad range of fitness and health-related features including personalized fitness goals, sleep data, and swim tracking. It also allows you to view notifications, and with some operating systems, sent text messages (Android allows this but IOS does not).

The Charge 3 has almost any fitness or health feature you could ask for. However, it is not a smartwatch. It does not feature onboard GPS (it connects to your phone's GPS) or an app store. If you're looking for something with more smartwatch functionality, check out the Ionic or Versa.

  • 24/7 Heart Rate: A continuous heart rate monitor allows for better calorie data, workout optimization, and health trends to help you achieve your fitness goals.
  • Swim-Proof Design: Unlike the Charge 2, the Charge 3 is swim-proof and wearable in the shower, and includes features that allow you to track pool workouts.
  • Notifications and Apps: With this Fitbit, you can see call, text, calendar, and app alerts, and check the weather. If you use Android, you can also send quick replies.
  • Goal-Based Excercise: Pick from one of the 15+ exercise modes and set a goal: time, distance, or calories burned.
  • Auto Sleep-Tracking: The Charge 3 allows you to track sleep time and quality, and use features that allow you to set a schedule and create a consistent sleep routine.

Fitbit Flex 2

The Flex 2 is a cheaper option for people who want simple yet powerful functionality in the Fitbit app.  Although the Flex 2 lacks some of the functionality of higher-end models, it has all the essentials and acts as a perfect introductory level device. It's tracking functionality includes sleep data, all day activity tracking, and swim tracking.

Despite this broad fitness functionality, this affordable fitness tracker makes a few sacrifices compared to the more expensive models. It does not feature a heart rate tracker, which means you lose out on some workout optimization information, and the calorie counter may be a bit less accurate. It also does not have a touch-screen display, featuring LED lights instead. This means you will not be able to see on-screen notifications, but you can still access fitness data in Fitbit's easy-to-use app.

  • LED Progress Display: Although this tracker does not have a touch-screen display, the LED strip shows progress for your daily goal and lights up when you get important notifications.
  • All-Day Activity Tracking: The Flex 2 tracks activities such as steps, calories burned, and active minutes 24/7. When you begin a workout, the exercise tracking automatically kicks in, and you can see workouts in the app.
  • Auto Sleep-Tracking: The Flex 2 allows you to track sleep time and quality, and use features that allow you to set a schedule and create a consistent sleep routine.
  • Swim-Proof Design: The Flex 2 is swim-proof and wearable in the shower, and includes features that allow you to track pool workouts.

Fitbit Ionic

The Ionic is one of Fitbit's first true smartwatches. In many ways, it's similar to the Versa. Both feature 24/7 heart rate, smartphone notifications, phone-free music, on-screen coaching, and more. One major difference is that the Ionic includes built-in GPS, which expands the functionality without requiring you to work out with your phone.

The Ionic has the most thorough functionality of any of the Fitbits on this list. If there is one possible problem with this tracker, it's the appearance. The aluminum frame extends significantly past the end of the display, creating a more old-fashioned look that received mixed reviews.

  • Dynamic Personal Coaching: The Ionic's coaching feature leads you through your workout with on-screen guidance and demonstrations.
  • Store and Play Music: The Ionic allows you to store 300+ songs, and you can use the Pandora app to play songs whenever.
  • Built-In GPS: Built-in GPS allows to see pace, distance, and other workout stats on-screen while mapping your route, including elevation, all without your phone.
  • 24/7 Heart Rate: A continuous heart rate monitor allows for better calorie data, workout optimization, and health trends to help you achieve your fitness goals.
  • Swim-Proof Design: The Ionic is swim-proof and wearable in the shower, and includes features that allow you to track pool workouts.
  • Fitbit OS: Fitbit OS is the smartwatch operating system. It gives you apps to download (such as weather, Strava, or Pandora), personalized workout coaching, customizable dashboard, and more.

Fitbit Versa

The Versa is one of Fitbit's first true smartwatches. It uses Fitbit OS, allowing you to see phone notifications, download apps, customize appearance, and more. The Versa is very similar to the Ionic; both use Fitbit OS and feature 24/7 heart rate, phone-free music, on-screen coaching, and more.

The major difference between the Versa and Ionic is the GPS. The Versa, which is a smaller and cheaper model, uses connected GPS rather than built-in GPS. This means that if you want to use functionality such as pace, distance and elevation mapping, you need to carry your phone when exercising.

  • Dynamic Personal Coaching: The Versa's coaching feature leads you through your workout with on-screen guidance and demonstrations.
  • Store and Play Music: The Versa allows you to store 300+ songs, and you can use the Pandora app to play songs whenever.
  • 24/7 Heart Rate: A continuous heart rate monitor allows for better calorie data, workout optimization, and health trends to help you achieve your fitness goals.
  • Swim-Proof Design: The Versa is swim-proof and wearable in the shower, and includes features that allow you to track pool workouts.
  • Fitbit OS: Fitbit OS is the smartwatch operating system. It gives you apps to download (such as weather, Strava, or Pandora), personalized workout coaching, customizable dashboard, and more.
