The Ring 5 is 40% smaller than the Ring 4 — 6.09mm wide and 2.28mm thick, weighing as little as 2 grams — while improving sensor accuracy across finger sizes and skin tones.
Up to 9 days of continuous 24/7 tracking between charges, plus new Health Radar monitoring with blood pressure signals and nighttime breathing insights.
The Oura app supports iPhone and Android equally. Core health data syncs to Apple Health, Google Health Connect, and 40+ third-party fitness apps.
All health tracking features are included at no extra cost. No monthly membership required — all sleep staging, HRV trends, and health reports are free in the app.
The ring itself lasts 10–12 days on a charge. With the included charging case, total battery extends to 150+ days — the longest effective battery life in the smart ring category.
RingConn Gen 2 is one of the few smart rings under $400 to include sleep apnea risk monitoring, using SpO2 and respiratory rate sensors to flag potential breathing disruptions overnight.
The right pick depends on what you optimize for.
$299 vs $609 over 3 years.

5 sensors each.
Similar weight and comfort.
Health-focused wearers who want continuous biometric tracking without a watch on their wrist. Ideal for sleep researchers, recovery-focused athletes, and anyone who finds watches uncomfortable at night. Works with both iPhone and Android. The subscription is optional but unlocks most of the app's value.
