Oura has refined its ring sensors across four generations. The Ring 4's flattened LED array delivers more accurate SpO2 and heart rate data than previous generations, especially during sleep.
Up to 8 days of continuous 24/7 tracking between charges in a ring that weighs as little as 4 grams. No screen to drain — just sensors running around the clock.
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.
