N-body app for iPhone and iPad

N-body challenges you to find a way to send a planet to its goal in a series of solar systems ranging from single stars, binary systems and then to some of the recent choreography solutions including the figure eight and more.

Amazingly, physicists are still finding out new things about the motion of three equal-mass bodies, more than three hundred years after Newton solved the problem for two bodies. These new choreography solutions are fascinating and hypnotizing.

Version 1.5 is now FREE.

Future versions will allow in-app purchase of additional levels. Anyone who purchased 1.4 will receive these additional levels at no cost.
