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.
Access the entire watchOS app ecosystem, Apple Pay, Siri, and Family Setup — for $150 less than the Series 11.
Emergency SOS, fall detection, and Crash Detection give real safety value even without premium health sensors.
Available in Midnight, Starlight, Silver, and (PRODUCT)RED with a wide range of Apple Watch-compatible bands.
The right pick depends on what you optimize for.
$249 vs $396 over 3 years · no required subscription.
7 days vs 18h battery.
5 sensors · 0.5 Hz HR sampling.
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 →iPhone users who want Apple Watch's core experience — activity tracking, notifications, crash detection, and Apple Pay — at a lower price point. Ideal for kids, teens, or anyone upgrading from a much older watch without needing the advanced health sensors.
