You can enable Dropbox sync in ATracker -> Settings-> Settings.
If you want to sync data among multiple devices, please select “Migrate data into cloud” when you enable the Dropbox sync on the first device (the device which you want to keep all records), and select “Delete local data” on other devices (which data will be overwritten by the data on the first device).
It might take some seconds / minutes to enable the sync, depend on how much data to sync and the network speed, please do not force stop / kill ATracker App in the process.
By default, if the Dropbox sync is enabled in ATracker, the daily backup will be enabled.The daily backup can be enabled / disabled in the device settings.
Updated: We have user reports that in some case user need to have a native Dropbox app installed to make the sync authorisation work. If Dropbox cannot authorise ATracker data sync via Safari, please install the Dropbox app on your device. We will contact Dropbox support on the difference on authorisation process difference via Safari and Dropbox app, and try our best to smooth the process on ATracker side.
