I love my oura ring. As a very good recreational athlete (long distance runner) it is very important for me to monitor different aspects of my body in order to perform my best in training and competitions. Oura is very accurate and can detect all the changes that I also feel in my body, but did not know how to react to them before. I love the data that I get about my sleeping and overall readiness. I love how accurate it is to predict my periods, when I should take it more easy and when I can give it a go. I would recommend it to everyone who wants to take good care about their health.
