Chris Evans is working on an iPhone version of FreeMind. Since Apple does not yet allow Java on the iPhone, a straight port is out of the question. However, a program that reads and writes FreeMind files is still possible. Anyone interested in being a developer (or tester) of this version should send an e-mail to cevans42ca at yahoo dot ca. Those interested in trying out an alpha version can send their UDID, and I will send the latest version using the Ad-Hoc distribution profile. Mac OS X and/or membership in the Apple iPhone Developer Program are not required for testing. However, Mac OS X and membership in the Apple iPhone Developer Program are required to help with development.
For my thoughts so far on the interface, see iPhone Gestures.
For more information about the current state of FreeMind on the iPhone, see eMind.
