Welcome to the iKog program. This is a very simple utility designed to make the management of your to-do lists quick and easy. The emphasis is on speed and portability. The program is a text-only utility with no graphical user-interface but it does include some features specifically designed to help with techniques such as Getting Things Done (GTD). If you're looking for fancy menus and windows, then iKog is not for you. If you're comfortable with text-based applications, then perhaps you'll find it useful. Anyway its free, so you've got nothing to lose.
All the files you need are in the iKog files section.
