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.

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.
