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.
18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.
Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.
Amazfit's Personal Activity Intelligence score aggregates your daily activity into a single 0–100 health index, guiding you toward optimal activity levels.
The right pick depends on what you optimize for.
$50 vs $396 over 3 years · no required subscription.
18 days vs 7 days 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 →Budget-conscious users who want more features than a basic step counter — SpO2, stress, sleep analysis, and workout tracking — without paying for a full smartwatch. Works with both iPhone and Android.
