FAQs

Battery life on the Oura Ring 4 ranges from 5 to 8 days depending on your ring size and usage patterns. Smaller ring sizes such as size 7 have a smaller internal battery and will typically sit closer to the 5-day end of that range, while larger sizes such as size 11 can reach closer to 8 days. All sizes recharge in 20 to 80 minutes using the included size-specific charger and USB-C cable.

Yes. The Oura Ring 4 is water-resistant to 100m, making it suitable for swimming, showering, surfing and water sports. You can wear it at all times without any concern about water damage, which means its sleep and health tracking is never interrupted by morning showers or washing up.

The Oura Ring 4 is available in sizes 7, 8, 9, 10 and 11. Oura Ring sizes use their own scale that does not directly correspond to standard ring sizes, so it's important to use the Oura Ring 4 Sizing Kit to confirm your correct size before ordering. The sizing kit includes plastic trial rings so you can test the fit on different fingers over a day or two and confirm the size that feels most comfortable and secure.

Yes. The Oura Ring 4 includes 1 month of free Oura Membership, after which a subscription is required to access the full range of health insights and personalised guidance in the app. Membership provides access to all health scores, trends and features including readiness, sleep stages, cardiovascular age and more. Without a membership you can still use the ring, but detailed insights are limited.

Yes. The Oura Ring 4 is built from titanium for durability, is water-resistant to 100m and is designed for all-day, all-activity wear. Its accelerometer tracks movement continuously, detecting activity automatically and logging workouts including running, cycling and strength training. The ring's low-profile design and rounded interior make it comfortable to wear during grip-heavy activities such as weightlifting or racket sports.

The Oura Ring 4 uses Smart Sensing, an adaptive platform combining research-grade LEDs, a temperature sensor and an accelerometer, to continuously monitor your health day and night. Key insights include a daily Sleep Score and Readiness Score, heart rate and HRV trends, blood oxygen (SpO2), body temperature deviations, respiratory rate, stress levels, activity tracking and cardiovascular health metrics such as Cardiovascular Age and Cardio Capacity.

Oura recommends wearing the ring on the index finger for the most accurate sensor readings, as the sensors need to be positioned on the palm side of your finger. However, the ring can be worn on any finger where it fits snugly and comfortably and it's worth testing the sizing kit on multiple fingers before committing, as diameter can vary between your index, middle and ring fingers.

Yes. The Oura Ring 4 syncs wirelessly via Bluetooth to the Oura app, which is available for both iOS and Android smartphones. The app organises your data into Today, Vitals and My Health, giving you a clear and accessible view of your overall wellbeing over time.
