Z Planner is a small but intricate application that enables you to BrainStorm, build, plan and execute projects from the idea phase to having a step by step plan integrated in your schedule.
Here is some feedback entered by people that took the time to learn how to use it:
"Once you get how it works, it helps you get to the bottom of your project, and Get It Done. You need to read the help file. The reminders can be used independently as a basic planning tool."
"All in all, I find zPlanner an indispensable tool in my everyday life. It helps me manage my time very efficiently, and I find that everything I read in time management books and manuals can be easily applied and integrated into the program. Sometimes it takes me a minute or two to figure out a way to do that, but it's usually pretty straight-forward."
