Choose a Fitbit by the shape you’ll wear, whether you need GPS without your phone, and which features you’ll actually use. Google’s current lineup ranges from screenless Fitbit Air to tracker-style Inspire 3 and Charge 6, plus the watch-form Versa 4 and Sense 2. These are Google’s product distinctions, not independent test rankings.
Start with the form you’ll wear every day
A tracker that fits your routine is more useful than one with a longer feature list that spends time in a drawer. Google currently presents five Fitbit options: a screenless band, two tracker-style devices and two watches. Its Fitbit comparison distinguishes them by form and feature emphasis.

Decide whether you need GPS without your phone
Built-in GPS matters if you want a device to record outdoor workout pace and distance without carrying your phone for GPS. Google lists built-in GPS for Charge 6 and Versa 4. Its current comparison does not establish built-in GPS for Inspire 3, so don’t assume it can record a route independently. GPS behavior and feature support can depend on the model and workout; check the exact product details for your intended use.

Google says the Fitbit app became the Google Health app on May 19, 2026, and Fitbit Premium became Google Health Premium. The company’s transition information says the redesign and feature availability vary. Fitbit account users needed to move to a Google Account beginning May 19, 2026 to access Google Health.
Understand the limits of Fitbit ECG
Google says its ECG app records a 30-second reading to assess whether a heart rhythm shows signs of atrial fibrillation (AFib). Compatible Fitbit devices include Charge 6 and Sense 2, but availability is limited to supported locations. The feature is not intended for people under 22. Check Google’s ECG app information for the current country list and eligibility.
Best Value
- Inspire 3 is the tracker that helps you find your energy, do what you love and feel your best – all you have to do is wear it;
- Compatible with Apple iOS 16.4 or higher and Android OS 11.0 or higher
- Move more: Stay motivated with a Daily Readiness Score, Active Zone Minutes, all-day activity tracking and 24/7 heart rate, 40+ exercise modes, automatic exercise tracking, and reminders to move
- Stress less: Keep an eye on your well-being with a daily Stress Management Score, mindfulness sessions, relax breathing sessions, irregular heart rhythm notifications, SpO2, menstrual health tracking, resting heart rate, and more[1,2]
- Sleep better: Automatic sleep tracking, a daily detailed Sleep Score, smart wake vibrating alarm, and sleep mode help you improve your sleep quality[3]
An ECG result is not a diagnosis: Google says only a doctor can diagnose AFib, and that the app “can’t detect all heart conditions.” Do not treat a reading—or the absence of an alert—as proof that you do or do not have a heart condition.
