"Orbital" is an N-Body simulator that replicates the force of gravity acting on mass.

-Touch and drag across the screen to send groups of masses flying at each other, or switch to movement mode and move around the screen to observe the simulation unfolding before your eyes.

-Use the slider along the bottom of the screen to zoom in and out of the simulation.

-Handy delete button allows you to restart your simulation!

This is a reasonably realistic simulator; real life situations can be simulated with surprising accuracy. For example, this app is capable of simulating two clusters of masses in a binary orbit collapsing and coalescing under their own gravitational attraction, similar to how two black holes in a binary orbit might collapse and collide as one.

Even if you aren't interested in the potential astrophysical simulation side of things, it is always great fun to send stuff flying around the screen colliding into other stuff! This app offers great fun for all!!

If you feel anything is missing or would like to see anything done differently please do not hesitate to send feedback in, it would be much appreciated :)

PS: Please be warned that the calculations performed by this app are intense, creating hundreds of masses will likely make the application run very slowly, especially on older devices.
