Kids love smartphones and tablets very much because they may watch YouTube video, play games etc. If they spend much time with these devices, it may be harmful for their eyes. Once we give them the device, it's hard to get back.
A good solution is to schedule to power off and lock the device's screen automatically after some minutes then kids can't play with it. That's what Lock Timer for Kids does for you.
Lock Timer for Kids is very easy to use, full guide included in app. Just type a number of minutes and tap on button Start Timer, it will wait for that number of minutes then power off the screen.
There is no ads in this app. Enjoy!
