The Getting Things Done (GTD) method of organizing tasks is a favorite among productivity seekers, and many apps support it. Firetask might be simple, but it still manages to fit in the core elements of GTD.
GTD works by following a simple three-stage approach to managing tasks: collect, organize, and review. Firetask mirrors this approach nicely, with an inbox for collecting items, a Focus section for putting them into projects, and a Review section to scheduling those tasks on a calendar. The interface is simple, making the whole process very quick and painless--after all, spending long chunks of the day tinkering with a GTD app isn’t quite as productive as actually doing your work.
