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.
Access the entire watchOS app ecosystem, Apple Pay, Siri, and Family Setup — for $150 less than the Series 11.
Emergency SOS, fall detection, and Crash Detection give real safety value even without premium health sensors.
Available in Midnight, Starlight, Silver, and (PRODUCT)RED with a wide range of Apple Watch-compatible bands.
