英文介绍:Have a baby curious about shiny tablets and phones? Use this app as a
baby-game and, more importantly, to prevent random taps of a baby from
doing anything you may not want. This app will show a small piano a baby
can use to explore sounds in a mobile device. At the same time, it will
block any naive attempts at closing the app. The back, home and apps-menu
buttons will be blocked, and Android's top menu won't be available. This
ensures a baby can't accidentally close the game, preventing any actions on
the device you may not want.
