SwiftConvert is a nice simple app for people who need to swiftly convert between different number bases, as programmers often do. It supports bases of 2, 8, 10 and 16. Enter a number in any of those bases, and simultaneously see the number in every base. Just touch the display for the base you want to use for entry - the keyboard will adjust to fit that base. The binary keyboard even has a 64-bit grid display which lets you toggle any bit directly with your finger, giving you a key for each bit. You can copy the resulting number in any base, just hold your finger on the display you want and the "copy" menu item will appear.
