    I’ve been using the Oura Ring and honestly, it’s been amazing. It tracks my sleep, recovery, and daily activity in a way that’s actually easy to understand and useful. The insights help me make better decisions with my health, and I like that it’s comfortable enough to wear all day and night without even noticing it. Definitely one of the best health tools I’ve used.

    Wanted to love this ring but ended up returning after 3 weeks. It does not accurately catch exercise and thought I was sleeping when I was not. It was comfortable but possibly too loose, maybe would be more accurate if tight, but I would only take the gamble if you are okay with having to return. It is easy to setup and charges quickly, nice look, just wish it was more accurate.

    I have been using an Oura ring since generation one. This is my third Oura ring. It’s a fantastic product for monitoring not just sleep, but also general health. Unless you need the functionality of phone calls or music that a smart watch provides, this ring is all you need to track your health and fitness. I highly recommend it.

    I love my oura ring so far ~ with the Apple Health to Claude Integration I'm able to see my full health data in 1 place and use AI to report and ask questions about my health. I was hesitant because I lose so many rings but this one fit perfectly based on the sizing kit and I haven't had any issues.
