From the developer:
OCDisasm is a free and interactive Objective C disassembler for Mac users. It has been very useful in the development of the Mail Act-On and Mail Tags plug-ins for Mac OS X Mail app. Control and data flow are computed and on each disassembled line it’s possible to view the current values of registers, provided they can be statically determined.
