Baby Shaker users are presented with a series of baby images. As the baby begins to cry, players are supposed to shake their iPhones until a pair of X's appear over the baby's eyes. The App was released on Monday, but appears to have been taken down. (I found a "Bible Shaker" "Salt Shaker" and "Stress Shaker," but no "Baby Shaker.") Apple confirmed, via email, that it has removed the application.
According to the Sarah Jane Brain Foundation, a non-profit group, the App starts up with these words: "On a plane, on the bus, in a theater. Babies are everywhere you don't want them to be! They're always distracting you from preparing for that big presentation at work with their incessant crying. Before Baby Shaker there was nothing you could do about it." A developer called Sikalosoft is listed as the App's creator.
Probably a good thing that Apple took the thing down. The company has been playing up the fact that it is about to hit the billion download mark for its App Store. Seems like it would be a bit embarrassing for the company to have to tell the world that download number 1,000,000,000 was something called, ummm, "Baby Shaker."
