A 4-gram titanium ring that reads your sleep, heart rate, HRV and skin temperature from the finger — the place with the strongest signal on your body.
4.8/5 from 1,284 owners 30-day returns
Item 1 of 5
A health lab the size of a wedding band.
Sizing differs from other models
Order before 3 pm and your ring ships the same business day. Shipping is free, delivery takes 1–3 days. You have 30 days to return it for a full refund — we only ask that it comes back in resalable condition with its accessories.
Fingers carry a clean, steady pulse. Health Radar reads it with a redesigned sensor array that locks on in seconds — during intervals, cold mornings and restless nights.
Grade 5 titanium with a PVD coating, brushed or polished. Water resistant to 100 metres, and light enough to forget you are wearing it.
6–9 days on a single charge and a full top-up in 80 minutes on the dock. Charge it while you shower and never think about it again.
Every morning: Sleep, Readiness and Activity, built from your own baseline — not from population averages. The app tells you what to do about it.
Why owners stay
Light, deep and REM phases detected from movement, temperature and heart rate — then matched against how you actually feel the next day.
Skin temperature and resting heart rate are compared with your own baseline, so day-to-day changes are easier to notice. Wellness insight only — not a medical alert.
HRV, temperature and recovery load combine into one number that tells you whether to push or to back off.
Nothing buzzes, nothing lights up. Your data waits for you in the app instead of interrupting your day.
Apple Health, Google Health Connect and Strava — your ring feeds the rest of your stack.

Sizing
The ring has to sit snug without squeezing: the sensors read through your skin and will not tolerate a loose fit. Ring 5 sizing differs from earlier models, so measure again even if you own a Ring 4.
Wrap a strip of paper around your index finger and mark where it overlaps — fingers swell during the day.
Lay the strip against a ruler. Every 1.6 mm of circumference is the next size up.
Pick that size above. Between two sizes? Say so in the request and we will confirm before shipping.
Oura Membership
The ring collects the signal. The membership turns it into scores, trends and daily guidance — and keeps your whole history available.
Reviews
Health Radar locks onto my heart rate far faster during intervals — and the battery now lasts nine days instead of six.
My husband and I both wear one. We check our scores over breakfast and know who trains and who recovers.
The temperature trend line showed my baseline shifting, so I adjusted my training week instead of pushing through it.
You forget you are wearing it, and one charge lasts a week. Worth explaining the membership to my wife.
