    The sleep data is my favorite feature. I never knew what kind of sleep I got or how much. I also like the way it tracks my activities. I no longer need my Apple Watch for that so I can wear any watch I want.

    The Oura ring provides excellent insights into sleep patterns, activity, stress, and health. It continuously monitors breathing, heart rate and latency in terms of HRV and sleep to monitor signs on stress and any indicators that may need attention.

    I absolutely love this ring, the battery so far has been amazing. I just wish it was thinner. The app is great but you do have to pay for the membership which I didn’t realize until after I bought it. Otherwise it’s great

    Really enjoy the feed back it gives about sleep. I like this a lot more than the Apple Watch to track calories burned. Only thing I’m not thrilled about is that the battery does not last a full 8 days.
