What could be more exciting for a contractor and construction project manager than an App called "Finger CAD"? Neal writes that "(t)his app allows you to draw houses, bridges, plans of apartments, mechanical components, geometrical figures and more using your finger. Final designs can be saved and delivered using email."
There are even a number of LEED project Apps, like Green Pro:
"This app gives architects, engineers, owners, and contractors the ability to both access and track LEED credits for New Construction and Major Renovations. Users can access information about credit requirements and indicate when a particular requirement has been met."
