Smart Ring RingConn Gen 2 – black, size 13

Smarter sleep and health under control
RINGCONN Gen 2 tracks sleep stages, breathing, and signs of sleep apnea with high accuracy. It continuously measures heart rate, HRV, SpO2, skin temperature, and respiratory rate — helping you catch changes early and better understand how your body responds to load, stress, and recovery.

Lightweight, durable, and discreet
A titanium alloy body and medical-grade resin with a PVD finish provide high durability and safe skin contact. At just 2 mm thin and 2 g, you’ll barely notice it. IP68 water resistance (up to 100 m) handles handwashing, workouts, and everyday wear without limitations.

Long battery life with no subscription
A single charge lasts approximately 11–12 days, and up to 150 days with the charging case. Magnetic charging takes about 90 minutes, and Bluetooth 5.0 ensures a stable connection. The RINGCONN app for iOS and Android requires no subscription.
