The RingConn Gen 2 smart ring redefines health tracking for people who want deep sleep insights without a bulky wristband. If you're concerned about sleep apnea or simply want to monitor your overnight recovery, this ring delivers clinical-grade data in a comfortable, everyday form factor.
Unlike other wearables, the RingConn Gen 2 tracks sleep apnea using AI developed with leading universities. You get real-time Apnea-Hypopnea Index (AHI) readings and personalized insights through the app. No more guessing if you had a restless night—the ring tells you exactly what happened. Plus, there are no subscription fees. You unlock all features, including stress, heart rate, HRV, blood oxygen, and women's health tracking, right out of the box.
Before you buy, use the included sizing kit to find your perfect fit. The ring is waterproof to 100 meters, so you can wear it while swimming or showering. It also supports OTA updates, meaning your ring gets better over time with new features and improvements. With a 12-day battery life, you can wear it day and night without constant charging.
