The fitness tracker itself does not do timing by itself, it just reads and follows your smartphone’s time and format. When you successfully pair your watch with the FitCloudPro app via Bluetooth on your smartphone, the time and date on the fitness tracker will automatically update according to the settings on your smartphone.
Alternatively, you can adjust the Date & Time ( Function interface > Settings > Date&Time ) on the tracker. It is recommended to connect the fitness tracker with the app, as it can automatically update the time and date based on your smartphone’s settings.
