Create, touch and drag interactive simulations of many balls joined together by springs. Surprisingly addictive fun!
Springs couldn't be easier to use, working well as both a creative app and a stress relieving executive toy for the iPhone era!
★ Unleash hundreds of balls and thousands of springs
★ Anchors - turn any ball into a fixed anchor with a double tap
★ Pause/Play to freeze the action
★ Chromodynamics - coloured balls introduce colour related spring strength
★ Electric Charge - charge your balls and watch them fly apart!
Hooke's Law, Coulomb's Law and the Runge Kutta have never been so much fun! (Don't worry, the Physics is hidden away behind the scenes leaving you free to enjoy the app!)
• Springs is now free!
• More balls! More springs! Create more complex models.
• iPhone 5 screen size support.
• Much faster drawing of models with tens of thousands of springs.
• Tweaks to the interface.
• Load and save your models (requires an In App Purchase.)
