I know, I know - we've been blogging so many GTD apps
lately that you probably needed to create a new task list just to look through them and make a decision. iGTD
, however, packs one heckuva punch, so I thought it would be worth mentioning. While it includes all the typical features one probably expects from a GTD implementation these days, iGTD brings a lot of power to the table with features like Address Book integration, drag and drop task creation from files, URLs and Mail.app messages, task tagging, 'maybe' tasks, flagging, a unique 'wait for' task class, keyboard shortcuts, Quicksilver integration, phone/PDA syncing, a menubar helper, searching... and even more
With all these features, iGTD is amazingly donationware
, and I highly recommend showing the developer some love after all this work.
