iOS: You might need a floor plan of a room but you don't always have one handy. If you can't ask for one and don't want to go through all the trouble of drawing it yourself, an incredibly clever app called RoomScan can draw one for you in about a minute.


How? You just tap the phone against a wall, wait for a beep, and then tap it against another wall. As you move around the room you'll see your phone draw the floor plan. When you're all done, it'll make some corrections to what you've accomplished by tapping and give you a finished image. Initial use might cause some frustration as the swift movements it suggests can cause the app to fail in its task. I found that gentle, slower movements helped the app track the phone's position and draw the floorplan much more easily. While some users have complained about usability, with a little practice it's not too hard to get right and, in theory, it should improve in the future. Either way it's a really smart idea and free to download on the iTunes App Store.
