The app, intended no doubt to be humorous, displayed a picture of a baby on the phone's screen and played a recording of a baby crying. The user then had to shake the iPhone vigorously until red X's appeared on the baby's eyes and the crying stopped. The app, which is no longer available, was available in 2 versions, The Single Baby Original for $1 or the Octomom ‘Shake n’ Bake’ for $8.
