Every time you open the NOERDEN App, your watch will connect automatically with the App via Bluetooth.
The data synchronization process will then begin. After a few seconds your data will be fully synchronized.
For LIFE/LIFE+/MATE/MATE+/CITY watch models:
You can synchronize your data manually by sliding your finger down at the top of any App page and releasing it when the "Release to Refresh" command appears.
If synchronization does not occur immediately, there may be insufficient data to transfer or your phone may need more time to sync. Wait a few seconds and try again.
