Oura 4 does it all !!! Plenty of facts about your body that explain why you act and feel the way you do !! No more guessing and actually predicts what's next !! Very impressed ! Buying my spouse one now !! She was jealous of mine !! Haha !

I bought this to track my cardio while playing drums. It’s comfortable, great for sleep tracking and the battery life is fantastic.

The set up was easy. I sized my ring finger in store and it was accurate to the product. The information provided by the app is helpful in managing my health and routines. This is a great monitor, not for fitness tracking.
