Why buy each?

Amazfit Balance

3,000-nit sapphire AMOLED with 21-day battery

The 1.5" AMOLED is 50% brighter than the Balance 2 at 3,000 nits, under scratch-resistant sapphire glass — with 21 days of typical use and 41 hours of Accuracy-Mode GPS.

Faster dual-band GPS and offline maps

An upgraded processor renders maps 2.5× faster, with dual-frequency L1+L5 GPS across six satellite systems, 64GB of storage, and turn-by-turn offline topo navigation.

Flashlight, HYROX, and 180+ sport modes

A new dual-mode LED flashlight with white, red, and SOS modes joins official HYROX training, golf course maps, and more than 180 sport modes.

Fitbit Air

$99 with no subscription

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.

24/7 health monitoring in 12 grams

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.

7-day battery with 5-minute fast charge

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.

Pick the Fitbit Air if…

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.
