This app is okay for restricting video and gaming apps, but if your child likes to mess about on the phone in general, there's no way to lock it completely. Your child can choose emergency from the lock screen, tap some numbers and create a new contact, and that allows you to unlock the phone. New issues: Can access Chrome although it is blocked, can sign in using account without permission despite the settings saying they can't. It would also be good if you could disable Google Search.
