Magic Plan (Free) Magic Plan might be ideal for civil engineer and architects, but it could also prove to be a handy app for common people. This augmented reality app creates floor maps of properties by just using the iPad camera. It takes some practice to use the app, but it is not tough to master. The app can also tell you how much area a room or a particular property has. Try using this app while you are scouting for a new house. No property dealer will cheat you henceforth.
