Every night, Aura transforms sleep, recovery and readiness into a clear score — so you always know how to perform.
Heart rate, HRV and temperature are read from the finger, where the signal is at its purest.

Validated against clinical polysomnography for sleep stage accuracy you can trust.

Aerospace-grade titanium, waterproof to 100 m, a full week of battery on a single charge.

Inside the ring, research-grade optical sensors read heart rate, HRV and temperature directly from the finger — the body's cleanest signal. Every morning, Aura distills it into a clear readiness score.
Recognized for outstanding product design — engineered to blend in on your finger and quietly do its job.

The readiness score is eerily accurate. On bad nights I can really feel it — now I plan around it instead of pushing through.
I stopped overtraining. The recovery data told me to rest and my numbers came back stronger within a week.
It's so light and comfortable that I genuinely forget it's on. Charge it once a week and that's it.
My temperature trend flagged something two days before I felt ill. That alone paid for the ring.
No monthly subscription, no screen, no hassle. It quietly does its job and the app is beautiful.
My smartwatch died every night and felt like a brick. This one lasts a week and I actually wear it to bed.
