For anyone prioritizing sleep health, the RingConn Gen 2 Smart Ring offers a groundbreaking approach. Developed with leading universities and hospitals, it's the world's first smart ring with clinically validated sleep apnea monitoring. Wear it comfortably all night to track your Apnea-Hypopnea Index (AHI) and receive personalized insights without the bulk of traditional devices. You'll wake up knowing exactly how you slept, not just guessing.
Unlike other health wearables, this ring requires no subscription fees—you get lifetime access to all features, from real-time heart rate and stress tracking to blood oxygen and sleep staging. The battery lasts up to 12 days (larger sizes), and the charging case extends life to over 150 days. With 100m water resistance and OTA updates for continuous improvement, it's built for daily wear and adventure. Choose your ring size carefully using the included sizing kit for a perfect, comfortable fit that won't interfere with your daily life.
