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.
ECG, blood pressure, body composition, SpO2, and advanced sleep coaching — all processed on-device with Galaxy AI.
Answer calls, control SmartThings, and use Galaxy AI features seamlessly across Galaxy phones and tablets.
Access Google Play, Google Maps, Google Wallet, and Samsung's polished One UI Watch 7 interface.
