Fitbit Inspire HR ( Amazon): The Fitbit Inspire HR and Inspire (below) have taken the place of the Alta series in Fitbit’s lineup.

If you’re doing that, of course, you might as well buy the Charge 4. You’ll also need to spring for the special edition model if you want Fitbit Pay support. It has nearly the same design and feature set, only the Charge 3 doesn’t have onboard GPS.

Fitbit Charge 3 ( Amazon): The Fitbit Charge 3 is essentially a cheaper Charge 4.

We suggest opting for the much-improved, newer model. It’s suitable for basic activity tracking, but don’t expect much from the display or design.

Fitbit Inspire 2 ( Amazon): The line’s previous generation, the Inspire 2, is a barebones fitness tracker.

It offers great value for basic activity tracking and features a beautiful, always-on display as well as continuous SpO2 monitoring.

Fitbit Inspire 3 ( Amazon): The Fitbit Inspire 3 is Fitbit’s budget fitness tracker.

All Charge 4 models have access to Fitbit Pay and a few other useful smartwatch features.

It’s the first Fitbit tracker with onboard GPS - something users had been clamoring for for years. Fitbit Charge 4 ( Amazon): The Fitbit Charge 4 is the company’s last-gen fitness tracker.It offers basic activity tracking similar to the Inspire 2 but comes with a much better-quality case and plenty of customization options. Fitbit Luxe ( Amazon): The Fitbit Luxe is Fitbit’s best-looking fitness tracker.Just be wary of the downsides because we found a few in our Fitbit Charge 5 review. It boasts a color AMOLED display (a first for the Charge line), as well as many advanced features, like SpO2 and skin temperature tracking, that feature on higher-end smartwatches. Fitbit Charge 5 ( Amazon): The Fitbit Charge 5 is the company’s flagship fitness tracker.
