You want the health insights of a smart ring without a monthly subscription. The RingConn Gen 2 delivers comprehensive sleep apnea monitoring, heart rate tracking, and stress analysis for a one-time purchase. Use it to keep tabs on your sleep quality overnight, then check your Wellness Balance Score each morning. The motion-triggered alerts are subtle, so you won't get spammed during meetings.
For accuracy, the ring uses four PPG sensors and a 3D accelerometer to track your sleep stages and overnight breathing. The dedicated app shows your AHI data and personal trends in a clear dashboard. With a 12-day battery life and a charging case that holds multiple top-ups, you can wear it constantly.
The RingConn Gen 2 is built for everyday use: titanium alloy with PVD coating is light (2–3g) and waterproof to 100m. It pairs with iOS and Android, and you can set it to vibrate for sedentary reminders or find my ring. The free app provides weekly and yearly reports, so you can track your progress over time.
