WHOOP-grade sleep and recovery tracking without the subscription — a 5-gram pod you'll forget you're wearing.

Fitbit Air

Fitbit

Google's screen-free debut gives you Fitbit's excellent sleep tracking, recovery, and AFib checks in a 5-gram pod with no mandatory subscription — the anti-WHOOP. There's no built-in GPS, and the deepest trends and AI coaching sit behind optional Premium, but the core is free.

The Fitbit Air is essentially a Fitbit Charge 6 with the screen removed — the same sensor pod, shrunk to a 5-gram pebble you clip into a band and forget about. Google's pitch is blunt: the same round-the-clock health tracking that WHOOP and Oura charge a subscription for, but with the core data free. You get continuous heart rate, HRV, skin temperature, resting heart rate, SpO2, AFib checks, and Fitbit's genuinely class-leading sleep staging — plus Cardio Load and a daily Readiness score to tell you how hard to go. Nap detection catches sleep as short as 20 minutes. Where it fits: this is a sleep-and-recovery tracker for people who don't want a watch on their wrist at night. There's no built-in GPS (it borrows your phone's), and the newest layer — a Gemini-powered Health Coach and the deepest historical trends — sits behind Fitbit Premium at $9.99/month, with three months included. But unlike WHOOP, you can ignore Premium entirely and still get the essentials for a one-time $99. It's new as of May 2026, and the workout heart-rate accuracy of such a tiny device is still being proven, but for screen-free tracking without a forever-subscription, nothing else is priced like this.

What we like

• ✓Fitbit's class-leading sleep tracking with no mandatory subscription
• ✓5-gram pod is barely-there — ideal for sleeping
• ✓Core recovery, HRV, and AFib checks are free
• ✓One-time $99, versus a yearly bill for WHOOP

Trade-offs

• −No built-in GPS — needs your phone for routes
• −AI coach and deepest trends require Premium ($9.99/mo)
• −Brand-new, so long-term workout heart-rate accuracy is unproven
• −No screen, so no glanceable stats or notifications
