Set play time limit on your phone !
Your kids are playing too much on the phone / tablet?
Now you can set up time for them to play!
To set up a play time, open Time'sApp,
Grant an admin right to lock screen
Choose how long you wish your kid will play this time
and click "Set play time!"
Once the time is met, the application will play a sound hinting the time is up,
lock the phone (if you chose to use "Lock the phone"
And will pop a message that the time is over.
*** Important ***
Time'sApp requests admin rights in order to lock the screen -- but that is the only administrative right we use.
