How to use

Place the ring on the finger that feels most comfortable for continuous wear and ensure a secure but not overly tight fit. Install the manufacturer's companion application on your Android or iOS device and follow the in-app pairing instructions to connect the ring via wireless communication.

Usage recommendations

For accurate tracking, wear the ring consistently on the same finger and keep the sensor area clean. Avoid exposing the ring to strong chemicals or high-temperature environments. Although IP68 provides protection against immersion, avoid prolonged submersion under extreme conditions and follow app prompts for firmware updates to maintain reliable performance.
