Smart ring RINGCONN Gen 2, size 11, black

Better sleep, better days
RINGCONN Gen 2 monitors sleep stages, breathing quality, and signs of sleep apnea with accuracy up to 90.7%. It continuously measures heart rate, HRV, SpO2, respiratory rate, and skin temperature, helping you quickly spot changes and understand why you wake up refreshed or tired.

All-day health and activity insights
The ring quietly tracks steps, calories, and workouts, helps manage stress in real time, and the Women’s Health feature in the app also forecasts your menstrual cycle. No distracting display, full access to data in the app, and no subscription.

Premium durability, long battery life
A titanium body and medical-grade resin with a PVD finish make it light, thin, and comfortable. IP68 ensures water resistance down to 100 m, Bluetooth 5.0 provides a stable connection, and the battery lasts about 11 days (up to 150 days with the charging case). For best accuracy, wear it on your index finger.
