How to use

Wear the ring on a comfortable finger so sensors maintain contact with the skin. Install the RingConn App 3.0 on a compatible Android device, pair the ring via Bluetooth, and follow the in‑app setup to enable continuous tracking and data sync. For sleep and apnea monitoring, wear the ring overnight; the device collects heart rate, blood oxygen, respiratory rate and movement data automatically. Charge the ring using the supplied USB‑C cable when the app or indicator notifies low battery to restore full functionality.

Usage recommendations

For the most accurate results, keep the sensor area clean and fit the ring snugly but comfortably. Wear the ring consistently during day and night to allow the app to learn your patterns and produce more precise AI‑driven insights. Avoid exposing the ring to strong chemicals or extreme temperatures; despite the IP68 protection, rinse and dry the ring after prolonged water exposure. Sync regularly with the RingConn App to back up your data and enable health summaries and personalized tips.
