The ultra-thin smart ring RINGCONN Gen 2 tracks sleep including sleep apnea with accuracy up to 90.7%, measures heart rate, HRV, SpO2, temperature and activity 24/7 – all without a subscription. Thanks to titanium, a weight of 2 g, thickness of 2 mm and IP68 (100 m) water resistance, it’s comfortable, durable, and discreet. Battery life up to 10 days (with the case up to 150 days) and stable Bluetooth 5.0 ensure smooth use.
Boost recovery and performance with detailed sleep tracking—from stages, breathing and SpO2 to temperature and cardiac activity. The ring helps timely recognition of sleep apnea signs, better training planning, and assessing your body’s response to load and stress. The app provides clear stats and recommendations with no subscription required.
Maximum comfort, minimal size: just 2 g and 2 mm combined with aerospace-grade titanium and medical resin. The PVD finish increases scratch resistance, while IP68 (up to 100 m) water resistance handles swimming and everyday wear. Single-charge battery life of about 10 days, up to 150 days with the charging case; fast magnetic charging in approximately 90 minutes.
