Gravity!2.2 - App Store
You'll be able to see results in few seconds.
Publisher Description
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 adjust the size, mass, and color of the particles! Zoom in and out and look around with two fingers!

Version History Improved the accuracy of the physics simulation, especially when enabling rotation. 2.2 Jul 29 This version (2.1.3) includes a fix for In-App Purchase issues with the previous version, as well as some minor UI improvements.
The previous version (2.1.2) introduced:
Experimental new feature for paid users: Orbit Assist
By turning on Orbit Assist, added planets will be sent in a trajectory computed to produce a good orbit rather than just the direction you swipe. There are 3 different orbit assist strategies, and the best choice will depend on the situation. Experiment and see what works! 2.1.3 Jun 16 Experimental new feature for paid users: Orbit Assist
By turning on Orbit Assist, added planets will be sent in a trajectory computed to produce a good orbit rather than just the direction you swipe. There are 3 different orbit assist strategies, and the best choice will depend on the situation. Experiment and see what works!
Also there have been improvements to Planet Trails and refinement of UI elements. 2.1.2 Jun 11 -Fixed a bug that causes the app to crash when placing planets on devices running iOS versions earlier than iOS 9.0
Undo button, improved Apple Watch support, and more are coming with the iOS 10 update in the fall. 2.1.1 06/24/2016 Another Huge Update!
