A free app for Android, by LADistribution.

Music Box for kids is an educational game, designed for children between the ages of 3 and 6. It is intended for preschoolers and kids in elementary school (6-9 year olds).

The app consists of 4 story levels, which all have the same basic plot. In the story, the app explains how a little Music Box got its start in a small German town. It then shows how the box moved from the town to Berlin. Along the way, the app also introduces various educational tasks for children to complete. These tasks develop various brain functions in kids (logic, spatial intelligence, memory and attention), with 4 levels of difficulty.
