About this app

Do you hand your smartphone to your child, then set this timer which force-locks when it runs out. So your child has to hand it you back because the phone and screen are lock.

This light utility app allows users to set a timer to lock phone and screen regardless of default system setting and whether user actively using or not. It will enforce entering password when the time is out.

To start, cancel or modify are protected by the default password to prevent "smart kids" to overwrite it.

This app uses the Device Administrator permission. This permission is required to allow app to lock the screen when the time runs out.

App widget added allows screen-lock at the touch of finger. Try adding widget to your shortcuts.

Exactly what I was looking for, i like watching streams when I go to sleep but it would drain my battery. With this I can set it to automatically lock itself. Really good if you want to listen to white noise until you fall asleep on YouTube without having your phone play hours on end until it dies. You can combine this with anything, this is the use I found.

The ONLY app that locks the phone after a certain set time! Very useful when for controlling kids' screentime! A small issue though, it adds 30 seconds extra to the original time we set.
