Overview

A slim wristband style fitness tracker, the Fitbit Inspire 3 focuses on heart rate, sleep and daily activity tracking rather than a large touchscreen or built in GPS. It sits in Fitbit's entry level tracker lineup, with a listed item weight of 3.8 ounces.

Fitbit has spent years narrowing this line down to the essentials: steps, heart rate, sleep and basic notifications, and the Inspire 3 continues that approach rather than chasing smartwatch feature lists.

Who it's for

People who want daily activity and sleep tracking on a light, low profile band will get the most from the Inspire 3, especially first time tracker buyers who do not need onboard GPS or a large display. Runners who train by pace and route are better served by a dedicated GPS watch.

Pros and cons

Pros
  • Compact, lightweight design at 3.8 ounces
Cons
  • No standalone GPS, depends on a paired phone
  • Listing omits battery life and display specs

Performance notes

The Inspire 3 leans on your phone for location data rather than carrying its own GPS chip, putting its own sensors to work on continuous heart rate and motion tracking through the day and overnight. That trade off keeps the device small and light at 3.8 ounces, at the cost of not working as a standalone run tracker away from your phone.
