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.
Unlike Oura Ring which requires a $5.99/month membership for full features, the Galaxy Ring's complete feature set is included in the $399.99 purchase price with no recurring fees.
Galaxy Ring pairs with Samsung's Galaxy AI to generate a daily Energy Score combining sleep quality, activity, and heart rate data — plus personalised Wellness Tips in Samsung Health.
Up to 7 days between charges and rated for 100m water resistance — suitable for swimming, showering, and continuous overnight sleep tracking.
