Essentially you just fire up the app which turns on the rear facing camera. You then tap a few buttons when you locate the corners of the room as you slowly rotate in a circle. Tap a few more buttons and you are done!
It will deliver a floor plan in several different file formats and even create a web site of the floor plan if you wish.
Although the app is free, and personal use is free, you have to purchase a plan in order to use it for commercial purposes or to publicly display the completed plan.
I was concerned about that until I saw that 1 plan costs $2.50 which is basically the cost of a cup of coffee. Having them create a web site centered on the completed plan is more expensive, but I can’t really see why you would want them to do that anyway.
Here is the iTunes link for the free app: https://itunes.apple.com/us/app/magicplan/id427424432?mt=8

Go take a look, download the app and give it a try. Who knows, this app may become your next favorite marketing tool!
