It offers discreet sensors to track sleep, readiness, and daily activity. An Oura Membership (sold separately) unlocks features like in-depth sleep analysis, personalized health insights, and live heart rate monitoring. The ring automatically detects and credits activities. The daily Readiness Score guides your activity levels. It is comfortable to wear day and night due to its non-allergenic, lightweight titanium design. With a battery life of up to 8 days, it allows for over a week of use without charging. The ring is water-resistant down to 100 meters, suitable for swimming and water sports. It monitors daytime stress levels to help build resilience and tracks heart rate for insights into cardiovascular age and capacity. Skin temperature tracking aids in illness detection and menstrual cycle insights. We recommend purchasing the Oura Ring 4 Sizing Kit for the most comfortable fit, as sizing differs from Gen3 and standard ring sizes. Wearing the sizer for 24 hours ensures the best fit. Some tracking and insight features require an Oura Membership. Non-paying members have access to daily Sleep, Readiness, and Activity scores, along with interactive Explore content.
