This app is a digital replica of the Galton Board, a device designed to demonstrate the central limit theorem. 

Just put your phone upright, you can watch how the balls fall, hit pegs, take different paths, and eventually fall into different bins at the bottom. 

In the end, you will find the bins in the middle hold more balls than those on the sides.
