## What is Springs'nThingsLite?

Springs'nThings - Version 1.8       
Both Physics and Fun

Springs ‘n Things is an entertaining demonstration application and educational display for the iPhone/iPad.  It simulates the dynamics of up to four springs connected to a moveable ball.  Touch, drag and release the ball to see it bounce around.  The length and stiffness of the springs can be individually adjusted.  One of the springs can be transformed into a fixed spring or a pendulum.  The ball can be made to respond to the tilting and shaking motions of the iPhone/iPad.  The motion of the ball can be perpetual or it can be slowed by spring resistance by viscous damping as if it were moving in air or water.

### 5/5 — Great app

*2015-09-06, version 1.5*

Lots of fun

### 5/5 — Boing!

*2015-09-02*

You can structure very cute bouncy things using the various settings (and fixed springs or pendulums)  or just give it to your 3 year old who will love ‘shooting’ it around the screen.

### 5/5 — Great physics

*2010-11-13*

This is adorable. It shows viscosity and springs and all kinds of physics stuff - but it looks so good, almost sexy. Very responsive to shaking. Removing all the springs makes it a balancing game. I love playing with it.

### 1/5 — WEEEEEEE

*2010-11-04*

This app is so much fun!!!

### 1/5 — Disappointing :(

*2010-06-13*

I don't understand the point of this app. Waste of time tbh :(
