The app has potential and would be very good, but a couple of issues make it almost irrelevant: 1. When my child reboots his mobile, it takes around 10 seconds to block preinstalled apps on his device. Plenty of time for him to use one of these apps to clone a game or two each time. 2. Cloned apps can't be seen or limited by Google family link. 3. The Google app can't be controlled, blocked or limited in any way.
