Discover the ultra-thin RingConn Gen 2 smart ring for everyday health monitoring without a subscription. It offers accurate sleep and apnea tracking, stress and daily activity monitoring, and 24/7 measurement of heart rate, HRV, SpO2, and temperature. Thanks to aircraft-grade titanium, a weight of just 2 g, and a thickness of 2 mm, it is exceptionally comfortable. Battery life lasts up to 11 days (up to 150 days with the charging case), with IP68 water resistance up to 100 m and stable Bluetooth 5.0 for seamless synchronization.
Improve sleep and recovery with detailed tracking of sleep stages, breathing quality, and sleep apnea indicators. The ring also continuously measures temperature and heart rhythm, helping you better understand why you wake up feeling rested or tired. Real-time stress analysis shows moments of overload before they affect your mood and performance.
Comprehensive 24/7 health overview includes heart rate, HRV, SpO2, respiratory rate, and skin temperature – all without a display to keep you free from distractions. The RINGCONN app (iOS/Android) provides overviews of steps, calories, and workouts. It also includes a women's health mode with cycle prediction based on temperature changes.
Premium materials and battery life: a titanium alloy and medical-grade resin with a PVD finish provide durability and comfort. IP68 water resistance (up to 100 m) protects the ring during everyday use. The battery lasts approximately 11 days on a single charge, including magnetic charging in up to 90 minutes. With the charging case, you get power for up to 150 days.
