The Smart Sensing technology adapts to your finger for precise, continuous readings. One morning, your readiness score dips to 72. You recall a restless night, and the ring detected your elevated heart rate and body temperature shifts. Without a screen or buzz, the ring guided you toward a lighter day and an earlier bedtime, helping you trust your body's needs.
Wear the titanium ring 24/7. It resists water, survives workouts, and lasts up to 8 days per charge. You forget it is there. The Oura App and AI advisor turn over 50 health metrics, including women's health and stress levels, into clear guidance. After a tense afternoon, the app suggests a breathing session to lower your heart rate. Oura Ring 4 connects your habits to your health, so you make better choices effortlessly.
