Terrible. The ring absolutely does not stay connected on its own. If you forget to pull up the app in the morning? Your sleep tracking will be messed up. Even if you do track it sometimes it thinks I'm sleeping until 10am for some reason, even after getting out of bed, eating breakfast and going to work. Forget to open the app after work and it won't have your heart rate for the day. randomly decided to add 100,000 steps to me for some reason one day as well. Return your ring instead.

Horrible app & it NEVER WORKS!!! I bought this to track my steps as I don't like to wear watches. I would think that would be super simple but it's been a freaking headache. The worst app ever. I have to log in every time I want to see my numbers. The app disconnects from the ring every da where I have to uninstall & reinstall it & sometimes a few times before it even connects. The worst part is, for the app & the ring to sync, it HAS TO BE ON THE CHARGER, which I don't have with me all the time

Every night at midnight the units reset along with all the cards. So every morning you need to reset what cards you see and set the units. It's mostly accurate when checked with other devices. The step count is questionable. It doesn't measure sleep accurately if you work nights and sleep during the day. And there are no explanations on things it's measuring for HRV, readiness and stress level.
