Houdah Software

ACTPrinter is an extremely useful app that allows you to download any document you would otherwise print right to your iPhone. Once you go to Houdah Software's website and download the corresponding computer application, you're all set to go! This is one those app concepts that I'm really surprised isn't automatically included with the iPhone.

ACT Sudoku is an expansive sudoku gaming application that allows you to save games, choose difficulty levels and even make notes on which numbers you've used so far. It comes with basic instructions, techniques and game directions to help even the most confused novice.
