Oura Ring Horizon

The Oura Ring Gen 3 is probably the most mainstream smart ring, packing an array of health sensors into a discreet design. While it can track movement and exercise, sleep tracking is the Oura Ring’s claim to fame. What’s more, sleep tracking data and other factors are used to inform the user’s readiness, a score that does a better job of encouraging recovery than most other fitness trackers on the market.
