Oura Ring 4

About this item

• SIZE BEFORE YOU BUY - Oura Ring 4 sizes are different from standard ring sizes. Size yourself with the Oura Ring 4 Sizing Kit.
• OURA MEMBERSHIP - First month of membership is free with your purchase, $6.99/mo afterwards. Offer available to new members only. Or opt for the annual prepaid option for $79.99. Membership is tied to your account via the Oura App, not your physical ring.
• ACCURACY - SMART SENSING - Oura tracks over 30 biometrics, including sleep, activity, stress, heart health, and women’s health metrics. Oura Ring 4 is powered by Smart Sensing, which adapts to you — delivering accurate, continuous data, day and night.
• LONG LASTING BATTERY - With up to 8 days of battery life, no screens and no vibrations, Oura Ring 4 allows you to focus on the present. From a workout to a night out — you’re free to forget it’s on. Until you start getting compliments.
• DESIGNED FOR 24/7 WEAR - The updated design of the Oura Ring 4 is more comfortable, fits better than ever, and is water resistant. The first all-titanium smart ring combines exceptional durability with a gentle touch, even for sensitive skin.
