On main page there is MonoDevelop IDE, and MonoTo开发者_开发百科uch (IDE?)

MonoTouch vs MonoDevelop From the Wiki:

Unlike Mono applications MonoTouch "Apps" are compiled down to machine code targeted specifically at the Apple iPhone. This is necessary because the iPhone kernel prevents just-in-time compilers from executing on the device.
