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.
Dual-chip design keeps the main Snapdragon W5 dormant during light tasks, dramatically extending battery life beyond any rival Wear OS watch.
First Wear OS 6 device on the market — with ECG monitoring, EMG gesture control, and eSIM for standalone calling.
Larger and brighter display than Galaxy Watch 8 or Pixel Watch 4, with Hasselblad-tuned health sensors, starting at around $285.
The right pick depends on what you optimize for.
$285 vs $396 over 3 years · no required subscription.
7 days vs 6 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 →Android users who want a full-featured Wear OS smartwatch — ECG, eSIM, a large bright screen — at a price well below Samsung and Google competitors. A natural pairing with Xiaomi phones but fully compatible with any Android device.
