Oura Ring 5

About Oura Ring 5

Overview Oura Ring 5 is a smart ring rather than a watch or a band: a titanium ring you wear continuously that measures sleep, recovery and everyday health signals, and sends everything to the Oura App. Oura describes it as the world's smallest smart ring, weighing from 2 grams depending on size, 6.09 mm wide and 2.28 mm thick. It starts at $399 in Silver and Black, with the other four finishes at $499, and the full app experience runs on an Oura Membership after an included first month. Design and comfort The ring has a full titanium exterior and interior with a superhard PVD coating, and comes in six finishes: Silver and Black at $399, and Stealth, Brushed Silver, Gold and Deep Rose at $499. Sizes run from 6 to 13 in whole sizes only, and Oura's own sizing kit covers that same range, which matters because a ring cannot be adjusted after purchase the way a strap can. The sensor dome inside stands 0.7 mm proud. Oura rates it waterproof to 100 m / 328 ft and IP68 for water and dust, describing it as suitable for sauna and water sports but not diving, with an operating range of -10 to 54 ºC. Screenless by design There is no display on the ring and nothing to read on your hand. The ring collects data continuously and the insights are reviewed in the Oura App, which is a different pattern of use rather than a reduced one: nothing lights up, nothing buzzes with notifications, and you choose when to look. For some people that is the reason to pick a ring over a watch; for anyone who wants the time, alerts or live workout figures on their body, it is the reason not to. Sleep tracking Sleep is the centre of the product. Oura reports a Sleep Score built from total sleep, heart rate variability, nighttime movement, sleep regularity and more, alongside sleep stages covering deep, REM and light sleep. It also provides Bedtime Guidance and Nighttime Breathing, using red and infrared LEDs to measure blood oxygen levels and detect breathing disturbances. The form factor is relevant here: a ring is easier to keep on overnight than a watch, and with six to nine days of battery it rarely has to come off at bedtime to charge. Readiness and recovery Each morning Oura produces a Readiness Score from temperature trends, heart rate, sleep and other inputs, intended to show how prepared you are for the day. It sits alongside an Activity Score, which looks at activity levels, consistency over time and recovery time. The pattern is the same as other recovery-led wearables: a daily figure you are expected to plan around rather than a target to beat. Stress and resilience Daytime Stress shows how movement, activities and tags contribute to stress levels through the day, and Resilience tracks how well your body recovers from day-to-day physiological stress over a longer horizon. Both draw on the same continuous sensor data rather than requiring you to start anything. Health tracking The sensor set is two tri-LED emitters covering red, green and infrared light, two photodetectors, a digital temperature sensor and an accelerometer. From those Oura derives 24/7 heart rate monitoring, heart rate variability, respiration rate, blood oxygen sensing and temperature trends. On top sit longer-horizon cardiovascular readings: Cardiovascular Age, Cardio Capacity as a VO2 Max estimate, and Blood Pressure Signals. Temperature trends also drive cycle insights. Oura groups several of these under Health Radar, which includes Symptom Radar, a feature that watches biometrics such as average body temperature, respiratory rate, resting heart rate, heart rate variability and inactive time, and can flag signs of strain sometimes before symptoms of a cold or flu are felt. Activity tracking Oura automatically detects more than 40 activities with heart rate, and workouts can also be added manually or imported from third-party apps. The ring has no GPS of its own. For route, pace and distance the Oura App uses your phone's GPS, which means carrying the phone and leaving the app running in the background for the whole session. Oura also states the ring does not stream live heart rate to your phone screen during an activity. If recording a route without a phone matters, that is a structural limit of the form factor rather than a setting to change. Battery life Oura quotes typically six to nine days per charge, varying with ring size and usage, and about 80 minutes to charge over USB-C. A separate charging case is sold that Oura says returns a full day of battery in ten minutes. Connectivity is Bluetooth 5.0, and the ring supports an airplane mode. Oura App and integrations Everything is read in the Oura App, supported on iOS 16 and higher and Android 11 and higher, with Bluetooth 5.0 required on the phone. Oura documents an Apple Health integration on iOS and a Health Connect integration on Android, both requiring an active membership; Oura imports workouts, weight and height, and exports resting heart rate. Linking those apps also imports height, weight, age and sex, which then cannot be edited in Oura unless the apps are unlinked. Membership The ring is bought outright but the software is a subscription. Oura Membership is $5.99 per month or $69.99 per year in the US, and new members get one included month that begins when the ring is paired with the app. Without an active membership, Oura states you can still access your three daily scores, Readiness, Activity and Sleep, plus ring battery, basic profile information, app settings and the Explore content; the detailed analysis, personalised insights and the API sit behind the membership. So the ring keeps producing its headline numbers if you stop paying, while the layer most of the marketing describes does not. Who it may suit Oura Ring 5 may suit someone who wants thorough sleep and recovery data from something they can forget they are wearing, who prefers a ring to a watch or a wrist band, and who is content to read everything in an app. It suits people who value a device with no screen and no notifications. It is a weaker fit for anyone who wants on-device workout controls, GPS without a phone, or a one-off purchase with no recurring cost. Important considerations Oura states that Health Radar features are intended for general wellness purposes only and are not intended to diagnose, treat, cure, mitigate, monitor or prevent any disease, illness or medical condition, and do not provide medical advice. Oura further states this information should not be used to replace clinical assessment, to make medical decisions, or to delay, stop or modify medical care, and that anyone with health concerns should consult a doctor or other qualified healthcare professional. Feature availability can vary by region and by membership status. Sizes run 6 to 13 in whole sizes only, so sizing before purchase matters. Prices, membership terms and feature availability change; confirm current terms on Oura's own site before buying.
