Smart ring activity tracker Rubicon RingConn Gen 2 — Silver, battery 12 days, Li‑Ion 13.5 mAh, USB‑C

Rubicon RingConn Gen 2 is a compact, round smart ring activity tracker in silver designed for continuous activity and advanced sleep health monitoring. The device measures blood oxygen, heart rate, skin temperature, respiratory rate and sleep apnea metrics while you sleep, and syncs data to the RingConn App 3.0 for AI-powered health insights without subscription. With IP68 water resistance and a 13.5 mAh Li‑Ion battery that supports up to 12 days of typical use, the ring is built for daily wear and multi-day monitoring.

Advantages

The RingConn Gen 2 provides detailed sleep apnea metrics such as Apnea‑Hypopnea Index and Oxygen Desaturation Index alongside continuous SpO2, heart rate and respiratory measurements. Its lightweight, thin form factor (approximately 2 mm thickness, 6.8 mm width and 2–3 g weight) and ergonomic interior rounding offer comfortable long-term wear. The device includes fast on‑the‑go charging with a charging case, USB‑C support, Bluetooth 5.0 connectivity and up to 10–12 days of battery life with quick charge capability.

Suitable for

• Users who want continuous sleep health tracking and sleep apnea monitoring
• People seeking multi‑day activity and biometric monitoring with minimal charging
• Active users who need a water‑resistant wearable for exercise, swimming or showering
• Anyone who prefers a discreet, lightweight tracker that syncs with Apple Health and Google Fit

When it may not be suitable

The RingConn Gen 2 is not a medical diagnostic device and should not replace professional medical evaluation for sleep disorders; its sleep apnea metrics are intended for personal monitoring and early detection rather than definitive diagnosis. Users requiring continuous clinical monitoring, specialized medical sensors, or regulatory‑grade devices should consult healthcare professionals and consider medical devices certified for diagnostic use.
