The "LeFun Health" app needs to connect to the ring via Bluetooth on your phone, so make sure Bluetooth is enabled and the app automatically connects to the ring when launched. Even when not connected to the phone, the ring can independently perform body monitoring and record blood oxygen and heart rate status also. The data will be updated within the app once connected.
