![]() ![]() We received a software upgrade for the feature after one month of wearing the device, and after initially struggling to get this to work, we finally got to test it. Oura says the sensors “shine red and infrared light into your finger and use the reflected light that bounces back to estimate how much oxygen is in your blood”.’ The Gen3 model houses a red LED sensor to monitor your blood oxygen as you sleep this can give you some indication as to your sleep quality. This also proves useful for period-tracking (more on that below.) Blood oxygen levels With this in mind, the Oura ring is fitted with “research-grade” temperature sensors to help you keep an eye on any unusual variations in temperature that could indicate high stress levels or potential signs of illness. Research indicates that skin temperature can detect stress in the body – as detailed in this study in Physiology & Behavior (opens in new tab). We also found the workout detection didn’t accurately reflect our exercise routine you can retrospectively modify this each time, but it’s fussy and time-consuming. However, we didn’t find this accurate, with the device wildly overestimating how many calories we’d burned. ![]() The app also tracks calories (opens in new tab), total calorie burn, walking distance and step count. You also have the option to manually input and record different exercise types via the app too. Any exercise picked up will contribute to your daily activity score at the end of the day. The band can auto-detect 30+ different types of exercise, so when you start working out the ring should automatically record the data. The band will also track heart rate variability (the interval between heartbeats) during your sleep, which can be used to monitor things like sleep quality and stress. It will take these measurements throughout the day, so that you can see how your heart rate is affected by your schedule. Oura has designed the ring to take measurements from your finger – near the radial artery – so that it can gather readings as accurately as possible. Opening this section on the app will give you a view of your daily body temperature, respiratory rate, and heart rate alongside a sliding scale of other readiness contributors (such as sleep, activity, HRV, and recovery.) If your readiness score is low, you might want to prioritize active recovery over a 10km run. The readiness feature on the app analyzes streams of data to give you an overall readiness score. We also really liked the ‘explore’ section on the app, which gives you access to a wealth of guided meditations, breathing exercises, sleep scapes and learning soundbites.īelow, we’ve gone into a bit more details on some of the other main features. Three scores displayed in the app (readiness, sleep, and activity) provide a holistic view of what Oura calls your ‘personal baselines’ with a daily score dictating what your focus for the day should be – rest or activity. That said, the app is still a useful bit of software, giving you a lot of data to analyze. But it can be frustrating if you want live feedback during a workout – there’s no way to immediately bring up your heart rate, which you might want to know when you’re training. The app is useful for giving you an overview of your day you can see how your body reacts to things like workouts, stress and sleep over 24 hours. You have to rely on a companion app instead. The company also suggests keeping it on non-stop for at least two weeks so that the device can ‘learn’ your body.īecause the device is so small, there’s no room for a screen. Oura recommends wearing the band on your index or middle finger for the most accurate results, with the sensors resting on the inside of your finger (palm side). The Gen3 model has three green LED sensors on the inner side of the ring, which are used for measuring things like body temperature and heart rate. We used the gold band for our testing, which is described by Oura as “the size of a wedding band,” but we found it to be considerably chunkier. It’s non-allergenic and non-metallic – which is great news for sensitive skin – and it’s also designed to be water resistant up to 328 feet (100 metres). So what does it look like? Well, it’s made from lightweight, durable titanium with a PVD coating and it weighs between four and six grams.
