Oura is also constantly updating its technology, paying particular attention to how to more accurately measure things like HRV, body temperature, and time spent in different sleep cycles: light sleep, REM sleep, and deep sleep. With this data, the app provides you with daily sleep metrics, activity metrics, and alertness metrics, as well as expert and scientific advice to optimize your health and well-being.

A readiness assessment, for example, is given in the morning and helps you decide whether you want to choose an intense workout or prefer rest and relaxation to help your body and mind recover. The Sleep Score measures how well you slept, including total time spent in bed, time in each sleep phase, resting heart rate, HRV, resting heart rate, and more. And the ring gives a more complete picture than just a dream.

It’s also a fitness tracker that accurately measures your steps, workouts, exercise volume and frequency, and any idle or recovery time. All metrics can be viewed in the brand’s app, which is easy to use and regularly updated as technology improves. It’s worth noting that I really love the fact that it’s wearable without screen because I sure don’t need another screen in my life.
