Sleep data I actually trust
Six weeks of half-marathon training and the readiness score tracked how I felt almost every morning. Wearing it in the pool was a non-issue.

Great ring, fussy for the gym
Great for recovery. I flipped it around during heavy deadlifts so the sensors would not dig in. Membership still stings.
