    Stats work fairly well. Need to really keep up with monitoring the information that is there. Over time I did have problems with my first ring not charging well. Will be interested to see how this second one does over time.

    I’ve been using my Oura Ring for a few weeks now and I’m really impressed. The sleep tracking is incredibly detailed and has helped me make real changes to my routine. I also like how it tracks activity and recovery without being bulky or distracting like a watch. The app is easy to use and very insightful. Definitely worth the investment if you're serious about health tracking!

    Fabulous addition to my active lifestyle. Best sleep tracking on the market. A complete studio of features on the app that hardly no one talks about. From Trends to meals to Health Panels etc.

    Even better than expected. Helps monitor daily activity and health. Some information is not available until several days or weeks data has been collected. I found the sleep pattern, heart rate, and oxygen saturation very interesting. You can “tag” various activities during your day, and it shows you how each activity affects your body. Fit is very important. Get the sizing kit before purchasing the ring. The kit says to wear the sizing ring for 24 hours. I recommend at least 2 days. My fingers change size depending on temperature and activity.
