Amazing health tracking tool
Love my Oura ring so far . Had it for few weeks . It’s amazing how much data it gives me in the morning when I wake up. I feel so motivated in the morning to keep up on my activity so I can beat my scores for the day before

Better than the Apple Watch for tracking
I’ve had this almost a month now, so I’m ready to review it and I previously used an Apple Watch song comparing things to that. I love that the ring can last six days it seems to stand up to that as well. The sleep tracking is much better than the watch. I get more in-depth information relating to my sleep. All around I’m happy with my purchase and recommend. I love the temperature tracking and heart rate variable tells me more in depth about my stress levels throughout the day and makes me more mindful.
