Sapiens is a mouse-gesture activated launcher that predicts the applications you will need.
Sapiens is an application launcher, it helps you access all the applications in your Mac. Sapiens is clever because it learns from you, so unlike any other launcher it predicts the applications you will likely need and offers a visualization of this prediction in an intuitive way.
Sapiens is activated by moving the mouse in a circle (yes, it is a mouse gesture that finally works), therefore touching the keyboard is really the last resort to be used in case you want to search for a specific application.
Sapiens is great for those of us who love the mouse and are tired of launching applications by typing (whether by using Spotlight or any other keyboard-based launcher).
