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.

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.

Great Fun

I've had this since it first came out and it is one of my favorite apps on the store. It may look somewhat unassuming at first, but it is load of fun and is super interesting. And -- the developer has been beginning to update it recently. I extremely highly recommend Gravity!
