Unlike WHOOP, there is no mandatory membership — pay $99 once and use Fitbit Air with the free Google Health app. Google Health Premium ($9.99/month) is optional.
Continuous heart rate, SpO2, HRV, and skin temperature tracking plus background FDA-certified AFib detection, in a 12g pebble designed to be worn and forgotten.
A week between charges, with a 5-minute top-up delivering a full day of use — significantly less downtime than WHOOP's slide-on charging system.
Pixel Watch 4 can detect when your heart stops and automatically call emergency services — a unique safety feature not found on Galaxy Watch or Apple Watch.
Six months of Fitbit Premium comes in the box, with daily readiness score, HRV analysis, and advanced sleep stages.
Google's cleanest Wear OS implementation with fast updates, Gemini AI on wrist, Google Maps, and Google Wallet built in.
The right pick depends on what you optimize for.
$396 vs $586 over 3 years · no required subscription.
7 days vs 1.5 days battery.
5 sensors.
12g · no required subscription.
Health-focused users who want passive, 24/7 biometric tracking without a screen on their wrist. Particularly strong for those drawn to WHOOP but put off by the subscription model — the Fitbit Air delivers comparable core health data for $99 outright. Works with both iOS and Android.
Full details →Pixel phone owners and Android users who want clean Wear OS integration, Fitbit health tracking, and safety-focused features. Ideal for fitness-focused users who prefer Google's approach over Samsung's more feature-packed ecosystem.
