Download Impromptu version 1.2 (Universal Binary) for OSX 10.4+ impromptu_1.2.dmg

NOTE! As of version 1.14 Impromptu uses Apple keybindings. A DefaultKeyBinding.dict file is included in the dmg. Certain impromptu keyboard shortcuts rely on this file which you will need to install in ~/Library/KeyBindings/DefaultKeyBinding.dict. If the directory ~/Library/KeyBindings does not exist just create it yourself.

I strongly suggest that new users take a look at the tutorials and the gallery. You can also watch a VERY brief video introduction here

Please let me know if you find a bug! Andrew Sorensen
