don't do it!!! waste of money, confusing lack of instructions, had to go on you tube to find out how to calibrate.. waste of time and money..
Works If you are familiar with mildot scopes then you may have seen the formula for figuring out range for a known object, such as a fire hydrant, man, etc. This works like that.
Wast of Money Complete waste of money. Easier to buy a tape measure and notepad to measure room sizes
waste of money instructions hard to follow, confusing.
Works quite nicely but initial calibration confusing Calibration is forced on you at first run, but instructions are not too clear. So watch the video before you try to launch the app. It REALLY DOES measure distances. Just don't panic if the calibration is confusing the first time! You can always go back and recalibrate if you need to. I really love the way you position the endpoints on the reference object AFTER the picture is taken. Very clever.
Not good not install useless How about I would take the measurement of the ceiling height of a room how can I put that credit card reference up there .? Such a waste of money for a stupid app If you go take the size of any given room you need to take ceiling height as well ...
