Kool app! Kool way to study orbital dynamics...and kill time! I LOVE the fact that it needs NO extra permissions! To many apps want into your info for no reason. Suggestions for your next update, add in an option for orbital race lines, so you can "see" the path of your "planets". Also a STOP button, to freeze everything.
It is fun but It is fun for a moment but not at all accurate. A planetary path tracer would be nice but that is not possible because this app does not do actual orbit path but rather a straight line or simi arch behind one of the suns. There is only one density for planets and suns. A binary system does not affect the satellite as a binary would but instead only one sun seems to exist regardless of how many you put on the screen. Fun at first but gets to simple and lame very fast.
Work it up and sell it! This is a really great start! Reading the other reviews, I can tell that lots of serious geeks were attracted to this. There complaints and disappointments should be fuel for your continuing on. First off, from an elementary perspective, this simulator shows very well the principles of attraction - from a mathematical, biological and astronomical perspective. Flash your screen over to a projector and kids have an instant lab. We need screen re-centering and mass release (explosion) limit settings.
Prett good simulation Its a decent thing to toy with. But it gets boring much faster than conventional apps. If it had more features or it had a puzzle, something other than tapping it would be great. But overall its a great app to play around with
Yay Pop Sci! Just received my copy of the Popular Science magazine. It mentioned this app. It's certainly a neat plaything. I had fun creating particle systems and Lorenz attractors. It would be more fun with default options that could be manipulated (such as default planet system) but I love it :3
Great, needs some improvements Any stationary body makes all other bodies gravitate toward it too quickly, so it is near impossible to create an object orbiting elliptically around a body. Worse though, the phone screen goes to sleep only a few seconds after the simulation begins, and you can't hold a finger on the screen to keep it from switching off because that affects the simulation by adding a body to the space
Project now maintained by Carlos Cheung
List of changes:
* Collision Effect
* Color generation improved
* Walls expanded outwards
* Default gravitational constant changed from 6.67E-7 to 6.67E-9
