Your AXTRO Fit 3 would sync automatically with your phone's date & time upon initial pairing and subsequent syncing with Healthy 365.
In the event of a discrepancy between your tracker and smartphone, kindly try the following steps:
1. Try manually syncing the tracker by pressing "Sync" button on Healthy 365
2. Force-close Healthy 365 and re-boot phone. Try step 1 again.
If it still fails to work, kindly contact HPB at 1800 567 2020
