is there a way to let an background app display something when other app is running?

Question

for example, if i'm playing a game, a trigger will display an alert after a certain time to warn me not playing too much time and should have a rest. Both android and iphone solution is welcome.

On ios you could use [Local notifications](http://stackoverflow.com/questions/13773123/how-can-i-schedule-local-notification-for-the-following-scenario) — David Karlsson, Jun 17 '13 at 15:34

On Android, using the following permission,

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

you can draw views on top of any other application. For example, this is the permission used by the Facebook Home app to draw its chat heads.

Also, this is a system permission, so it does come at a cost.

Think about it as on an Alarm Clock, which can interrupt your current App, something which is off-course possible.

Regarding Android you might want to read about AlarmManager

As for iPhone you might want to take a look in this Stackoverflow question discussing local notifications.
