About Onyx Ring

Wear Your Health.

Onyx Ring was created for people who track their health without the bulk. No bulky smartwatch. No constant buzzing. Just personal health insight into your heart, sleep, body temperature, oxygen and activity — from a titanium-finish ring you'll forget you're wearing.

The R09 is under 4 grams, 5 ATM waterproof, and runs 60+ days from the charging case. Works with iPhone and Android. No subscription, ever.

Onyx Ring is an Australian-owned brand based on the Gold Coast, QLD. We ship worldwide — free, with no fine print, in 7–10 business days — because the people who'll get the most from this ring don't all live in Australia. Questions, sizing help, anything: onyxring@outlook.com.
