The Compass has a fully 'skinnable' interface. This means that you may download new skins and change the user interface. The Screen Compass comes with a technical skin allowing greater control and a crosshair for easy alignment. From aesthetic to technical you should find onscreen solution that suits your needs.

Unlike the compass that you may use on your drawing board the Screen Compass is not limited to simply drawing circles. Using the 'Shapes' menu you can choose to use a triangle, square, pentagon or any number of sided polygon up to the 39 sided Triacontakaienneagon.

The Units menu allows you to choose a new unit from the list of predefined units including pixels, inches and centimeters. You may also configure your own Custom Units using the 'Calibrate Units' menu option. Choosing this option will bring up a screen which allows you to choose a Custom Unit, rename and set the scale.
