This app simulates the effects of gravity. You can fling particles at each other and watch them interact. Create solar systems and galaxies! Make a planet and fling asteroids into it! Add a black hole and watch everything get sucked in! You can even adjust the size, mass, and color of the particles! Zoom in and out and look around with two fingers!

Fun but kinda boaring

This fun to mess around for a few minuets but there just isn't enough to do.

Enjoyable but needs improvements

The app is worth the $.99 upgrade. I'm glad I bought it. But it needs some little improvements like an "undo" button for unwanted planets or orbits you don't like. It would aka be good to add a feature in which you can track a planet that is moving. When a planet moves off screen, you have to manually adjust the screen to view it. Also, too many planets cause the app to lag.

There's some good potential!

(If you get my joke.) I love this game it's definitely fun to mess with. It would be better if you could add more things to this though, like stars that act similar to black holes that "eat" matter. The version I'm using doesn't have rotation and I feel kinda bummed out. It's also difficult to create orbits too. So maybe have some preset objects like solar systems, or random solar system or something.
