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.
A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.
Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.
Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.
The right pick depends on what you optimize for.
$396 vs $476 over 3 years.
7 days battery each.
5 sensors each.
12g.
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 →Anyone who wants a slim tracker with a screen, built-in GPS, and ECG rather than a full smartwatch. It suits Charge owners ready to upgrade, as long as they don't rely on Google Wallet payments or EDA stress scans. Works with both Android and iPhone via the Google Health app.
