The bottom line The Oura Ring Gen3 Horizon is the smart ring tracker that monitors sleep, recovery, and activity 24/7 without a screen at $349 + $5.99/month membership. The titanium ring weighs 4-6 grams (lighter than most wedding rings) and stays comfortable during sleep and workouts, the 7-day battery between charges is the longest in the wearable category (vs Apple Watch 18 hours), the 7 sensors track skin temperature, heart rate, HRV, blood oxygen, accelerometer, and infrared photoplethysmography continuously, the Oura app uses AI to score Sleep, Readiness, and Activity daily with longitudinal trend analysis, the no-screen design eliminates notification fatigue (vs Apple Watch), the medical-grade research backs sleep science (10+ peer-reviewed papers), and the 8 ring sizes (6-13) fit most fingers. The trade is the $5.99/month membership for full app features and a ring-form that limits display feedback.
