Device Data Usage

How much data does the FamilyTime app use?

It’s not very much, at all because all of the processing takes place on the Internet; the app itself needs very little data to run. In addition, it is designed to switch seamlessly to use Wi-Fi when available, which further reduces the amount of mobile data it uses.
However, because FamilyTime does require an active data connection to sync, you would need either a data connection on the device or Wi-Fi connectivity.
