Like many successful smartphone games, the goal of Send Me to Heaven is easily communicated. Unlike other games, the goal is to throw your phone as high as you can, then catch it. It's available on Android, but not the App Store. Apple determined the game was "encouraging behavior that could result in damage to the user's device," and thus did cast Send Me to Heaven out of its walled garden paradise. App creator Petr Svarovsky told WIRED that he was disappointed by the ban. The 50-year-old from Prague said he had hoped to have people shatter as many iPhones as possible. "The original idea was to have very expensive gadgets, which people in certain societies buy just to show off, and to get them to throw it," he said via Skype.

Svarovsky takes the time that the phone was in zero gravity, divides it by two, and inserts it into a free-fall formula. It's surprisingly precise on most phones, he says, although some models of Android phones work better than others. The method Svarovsky uses to calculate the height means Send Me to Heaven won't work with extreme stunts, like hurling it from a cliff or take it skydiving. Any time your phone falls further than it rose, the app returns an error.
