It seems there's more Getting Things Done inspired software packages out there than there are Flash games littering the web. It's understandable; GTD has become the geek mantra for productivity, and finding the right tool to suit your GTD needs is like searching for the holy grail.

For Mac users, that holy grail may be iGTD. iGTD is a free Mac program that pulls from all of the GTD principles to provide a very concise platform for manging your projects and next actions. Links with Quicksilver and the ability to handle URLs that are drag-and-dropped onto it make using iGTD a seamless experience, and it even synchronizes your tasks out to iCal. In fact, the pairing of iCal and iGTD work very well together. iGTD functions as the management interface, where you manipulate your tasks and projects, and iCal can be your dashboard when you're actually trying to get things done.

If you're still searching about for the right GTD solution and you're a Mac user, give iGTD a try before you shell out big bucks for some other solution. It's free, so there's nothing to lose, right? Except maybe a couple days of messing around with all of your lists... but that's productive, right?
