Smart Ring
The ring that knows you.
24/7 health tracking in a featherlight design. Sleep, heart rate, HRV and recovery — no watch, no screen, no subscription.
What it tracks
More insight than a watch, less on your wrist
Wellness device, not a medical device. OSAWALLA rings and the OSAWALLA app are intended for general wellness and fitness use. They do not diagnose, treat, cure or prevent any disease, and readings should not be used for medical decisions. Consult a qualified clinician for any health concern.
Sleep, measured properly
Wake up knowing how you slept.
Worn all night without you noticing it, the ring reads your night from the finger — where pulse and temperature signals are strongest. A typical night looks like this:
Stage splits are estimates, the same as on any wearable. The trend across weeks is the useful signal — the app shows both.
Choose your series
Three rings. One mission.
The sensor array and the app are identical across all three — width, weight and finish are the only variables.

5 to 7 days of continuous wear, with a full charge in about an hour on the magnetic charger.
