StateCraft.

StateCraft is a new kind of task manager designed for a more mindful approach to work and life. It's built on a simple idea: you can get more done with less stress by honoring your natural energy levels. Instead of a single, overwhelming list, StateCraft helps you sort your tasks into personal "states of mind" like 'Creative,' 'Focused,' or 'Relaxed.' When you feel energized, tackle your focus tasks. When you're tired, work on your low-energy items.
