Relativity Widget app for iPhone and iPad

Relativity Widget allows you to visualise Einsteins theories of relativity right on your home screen.
Two modes :
• Special Relativity: imagine that you are in a spaceship travelling at a chosen speed. If you travel fast enough, time will pass differently on earth...
• General Relativity: you are on earth while a friend of yours went on a journey, in a spaceship, at a chosen distance to a Schwarzschild black hole. If you are close enough, time will pass differently in the spaceship...

Relativity Widget clocks represent the difference in time flow, since midnight, between a high speed / high gravity experiencing reference frame and a low speed / gravity one, according to Einsteins theory of relativity.
