Fitbit Comparison: Which Fitbit Activity Tracker is Best for You?

An activity tracker can be a great companion while you exercise, whether you are walking, going for a run, or doing a home workout.

Nowadays activity trackers do more than simply count your steps. They have multiple functions to help you monitor your fitness, sleep, heart rate, and more, but this can make it confusing when deciding what model is best for you.

Fitbit is one of the major providers of activity trackers and smartwatches. We’ve listed eight Fitbit models with some key information to help you compare prices, features and functionality, and find one that is most suited to your situation.

These models were available and their information correct at the time of writing. Since publication, new models and upgrades may have been released.

They count your steps and remind you to move if you’ve been sitting too long, and you can stay connected with smartphone alerts so you don’t miss a thing.

In addition to these functions, the Inspire HR tracker also comes with continuous heart-rate monitoring, a heart-rate zones tool, and guided breathing sessions, as well as different exercise modes and more in-depth sleep data. It can also connect to the GPS on your phone.
