BabyPhone is a keyboard game for children between 0 and 5 years old. Its strongest feature is the exclusive lock-mode. There’s no way to exit the game until you write the correct passcode.
Native Android application that uses custom hacks to achieve a secure environment for the game. Children playing the game cannot make phone calls, read notifications, etc. Everything, from the notification bar to the home button, is blocked, but the game :)
Available in English, Chinese, Spanish, Galician, Euskera, and Catalan.
