Would work great, except it doesnt

The free version worked fine, but I just bought the full version and I cant take new pictures. I have to use the regular camera and then use the picture in my library. But other than that the app does work great. It may not be 100% accurate, but its fine for estimates, which is all Id really need it for anyway. Ill give it 5 stars when they fix it.
