Note: Quadranto has been been discontinued. From the developer: "Thank you very much for your support in years! Unfortunately there is no time and energy left for me to give Quadranto the support and effort it needs to have in order to keep it as great as you guys deserve it to be."
Quadranto (was Eisenpower) is all about getting something done. The app is based on a quite popular productivity method known as The Eisenhower Principle.
Dwight D. Eisenhower, 34th President of the United States, came up with the idea that every single task can be qualified by the criteria important/ not important and urgent/ not urgent. That leads to a 4-quadrant structure, a.k.a. Eisenhower matrix. Quadranto reflects that structure and provides a canvas for prioritizing your to-do's by importance and urgency.
First of all there is a quadrant labeled "Do first". That section is for important as well as urgent tasks which should be done immediately and best by yourself. Then in the upper right corner we've got the "Schedule" category. This is for tasks that are indeed important but not that urgent so that you can easily schedule them for later handling. Next there is a "Delegate" section for urgent but not that important things. Those type of tasks can or better should be delegated to others. Finally there are also tasks that are neither important nor urgent. That's why the fourth section is labeled "Really?!". Due to their nature those things actually shouldn't be done at all...
But that is really not all what Quadranto is good for. With the ability to create as many sheets of the 4-quadrant canvas as necessary you can set priorities for each and every personal or professional project you're working on. You're also able to rename each of the four quadrants individually so that they fit your very own needs.
