How to use

Fit the RingConn Gen 2 on the finger with the indicated side facing outward and ensure a snug but comfortable fit to allow sensors to maintain contact with the skin. Install the RingConn App on a compatible Android device, enable Bluetooth and follow the in‑app pairing procedure. Wear the ring continuously for best sleep and activity tracking results; charge the device using the supplied USB‑C cable when battery levels are low. Data synchronizes automatically when the ring is in Bluetooth range and the app is open or running in the background, allowing you to review detailed sleep apnea and health summaries in the app.

Usage recommendations

For accurate sleep apnea and SpO2 measurements, wear the ring during sleep and keep the fit consistent night to night. Avoid applying lotions or heavy creams to the finger before wearing, and ensure the sensor area is clean. Use the app to enable sleep monitoring features and grant required permissions for Bluetooth and sensors. Regularly update the RingConn App and firmware when prompted to maintain measurement accuracy and battery efficiency.
