RoomScan

Need to quickly get the dimensions of a room? You could drop some serious coin on a laser-based measure, struggle with conventional tape, or just use RoomScan. This brilliant app lets you walk around the room, doing nothing but just touching each wall with your iPhone or iPad. it draws the floor plans automatically, whether it's a small square room or a complex layout, and measurements are estimated to the nearest half a foot, giving you both the wall lengths and square footage.
