This Application is something that I have been looking for, but it needs work. I think this will be hugely popular for contractors and those that have to make numerous measurements of spaces, and want to be able to document items and spaces. But it is difficult to move the dimension lines to different areas. When assigning dimensions to these lines It should also jump right to the number keyboard vs. the qwerty one. The garbage button also does not work on the drawing screen, you can delete the scrawling but not the dimensions.
I think this will be an awesomely popular app but the bugs have to be fixed first
