Fitbit Air
Buy/Wait:good

First-generation product — no historical cycle data to predict a successor

Best for: 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.

Why buy each?

Samsung Galaxy Watch

Best-in-class health tracking

ECG, blood pressure, body composition, SpO2, and advanced sleep coaching — all processed on-device with Galaxy AI.

Deep Samsung ecosystem integration

Answer calls, control SmartThings, and use Galaxy AI features seamlessly across Galaxy phones and tablets.

Full Wear OS with Google apps

Access Google Play, Google Maps, Google Wallet, and Samsung's polished One UI Watch 7 interface.

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.
