Baby Shaker

Baby Shaker was a bad app in more ways than one. It had users see how quickly they could get a virtual baby to stop crying by shaking their device as vigorously as possible--as if it were a real baby.

The simulated infanticide experience, which cost 99 cents, was pulled as soon as Apple caught wind of it. Apple then uncharacteristically apologized for it ever making it on there.

Creator Sikalosoft has since backpedaled on the merits of the app, noting that even the Grand Theft Auto series has not yet crossed such social thresholds. The developer also has two other apps that continue to exist: Dungeons ($2.99) and Dice Mosaic ($.99), neither of which have babies in them.
