We started Aura because the best health data is the kind you actually collect. So we placed lab-grade sensors in the only wearable you never take off — and left out the screen.

Aura started with a simple frustration: the wearables that promised to help us understand our health were the ones we kept taking off. Too bulky to sleep in, dead by morning, buzzing when we needed calm.
So we set out to build the opposite. A device you forget you're wearing, that reads your body from your finger — where the signal is cleanest — and converts every night into a single, honest number. No screen. No monthly fee. No noise.
Today, over 100,000 members wake up to their readiness score. We're just getting started.

We believe the best health tool is the one that disappears — no screen stealing your attention, no vibrating at the wrong moment.
Aura works quietly in the background, giving you an honest answer every morning, so you can put your energy into living, not tracking.
Lab-grade sensors and clinically validated sleep tracking — precision you can actually act on.
No subscription, ever. The ring and the full app are yours, and your health data stays yours.
