There are two ways to synchronize data: 1. Auto-sync data 2. Manual synchronization

• When the watch and APP are connected, the data will be synchronized in real time, and you can go to the status message at the top of the main interface.

• Different data synchronization mechanisms are different. For example, the pedometer data will be displayed in real time; the heart rate data needs to be synchronized before the measurement is completed; the sleep data needs to be fully synchronized after waking up.

• Normally, Bluetooth will be disconnected when the watch and the mobile phone are far apart (if the anti-lost alarm is turned on, an alarm may be given at this time), and will be automatically reconnected when it is approached again.

• However, it is not ruled out that the device cannot be reconnected in a special case (for example, if the disconnection time is too long and the surrounding signals interfere with the device), and the data cannot be synchronized. In this case, you can use the manual refresh method to synchronize the data.

• Manually synchronize data: Drag down on the main interface, APP will immediately initiate reconnection, and immediately synchronize data after successful reconnection. (Sometimes this operation needs to be repeated several times)

If the data synchronization fails manually, try the following methods

1.Restart APP

2.Restart the phone Bluetooth

3.Restart watch

4.restart the phone.
