Zcope is an online tool for tasks and projects management. The navigation menu is a variation on the classic “buttons menu”; in this case an arrow connects the selected item to the contents and leads user’s look downward.

Intervals is an online tool for project management and time tracking. The price of the product is a quite simple table, but with a very useful mouse over that highlights both rows and columns and thus greatly facilitates the reading of data.

I don’t  know exactly how to define Freckle: an application to manage time slash tasks slash projects?  Loved the graphic of its price plan.
