Crash App

The idea of this app is that when you click on button it crashes as usual. You can use it to play jokes on each other. For example, You can say that there is a new game that waited a long time for Your friend. It asks You to download it to her phone. You download app, and give him the phone. He opens the app, clicks on the "Install" button and... it crashes. He doesn't understand what happened, again enters the application and sees the lower button does "Not running?" He clicks on it and sees the notification "Sorry, but this application is not running on your device". In addition to this You can say "I told you that your phone is not pulling anything" etc
