I don´t know if there is any App which you can use to put a limitation to the time a user can play daily. If not I would like to do it.
I have 3 children, they spend hours playng everyday to diferent games like clash of clans, candy crush ... I would like to find the way to reduce, for example to 2 hours per day or 3 hours on saturday and sunday...., the time they can spend playing to all of them. The App should have a configuration tool where administratos decide the time and when they have been playing this time , it closes all the games and doesn´t allow to play until next day.
If you know this App, or if you have an idea to do it myself...
