Thanks for posting this. It is rather interesting to play with and has a good interface. I have a couple issues though. First I can't zoom in enough to be very precise with the placement and measurement. It would be nice if the zoom was not limited so much. Also, using a Samsung S5 I am having some trouble getting an accurate measurement. I put a ruler and a us letter paper in the same plane and took a photo at about a 30 degree angle. I'm seeing about a 12.7" measurement on a 12" ruler.
