SolarSim app for iPhone and iPad

Always looking forward to the universe, but for some reason, failed to realize my dream. Recently I’m watching Liu cixins Three Body, a whim, I can make a simulation applications running under the law of Newtons, hence the SolarSim. SolarSim, you can simulate the solar system, you can also add, delete, and change the parameters of each planet to observe the system evolve over time, and you can also speed up or slow down the speed. Finally, this is not a game, this is a real simulation program, hope you get happy. Have any suggestions, comments are welcome.
