Circuit Craft app for iPhone and iPad

Circuit Craft is an easy to use app for your iPad that lets you design, build and run digital circuits.
Based around a simple grid system, creating circuits is as simple as dragging tiles onto the board, draw wires connecting the tiles up and see it all work instantaneously in an always-on environment.

Circuit Craft comes with the following features:
* Input / Output tiles. Such as a switch, button, light and timer.
* Tiles to interface with the iPad. Such as microphone input, audio output and compass.
* Logic Gates: AND, OR, NAND, NOR, XOR, XNOR
* Flip Flops: JK and D
* 7-Segment displays (regular & binary)
* Adjust properties on tiles to suit your circuit design.

Custom chips can also be created to host your own circuits, and place them as a chip in another circuit.
