From the developer:
FingerCAD PRO is the CAD application for technical drawing with your fingers. With FingerCAD PRO you will be able to draw quickly homes, floor plans, decks, mechanical components, geometrical figures, electronic circuits, anything that can be designed with a CAD application. The "two-way sharing" feature lets you start a CAD project with your Mac and continue it with an iPad, iPad Mini, iPhone, or iTouch.
You may want to check out more software for Mac, such as RiffMaster Pro, Sequel Pro or WASEL Pro, which might be similar to FingerCAD PRO.
