Its development was inspired from David Allen's Getting Things Done concept of breaking down tasks into actionable items he calls widgets. When tasks are small and actionable, the only thing you have to think about is cranking them. No more procrastinating because your mind can't recall what things you need to do. All you have to do is KranK.
KranK helps reclaim the Dashboard as the focal point for everything you do on a computer. The Dashboard becomes your grounding point before jumping into the fray. KranK accomplishes this by showing the Dashboard at timed intervals to inquire if you are still working on a task. This helps you stay focused on what you have planned out in OmniFocus and allows you to glance at the other widgets running in the Dashboard.
KranK relies heavily on the concepts found in David Allen's Getting Things Done. If you are new to Getting Things Done, you may want to read the book, check out forums like Merlin Mann's 43 folders, and download OmniFocus.
