How to extend the app to other phones [iOS]

User Сomments: "Another question about the licence. If I got the full lifetime licence would it be only for me or could I extend to my daughter's cell phone?"

The app supports the Family Sharing feature, which means that the app can be installed on other devices on the Family Sharing list.

This function does not provide data sharing. The app is shared using the iCloud feature, and it works when you use the same Apple ID on different devices.
