I couldn't love this app anymore. Before I found this app I was about to pay another company several hundred dollars per month for my roofing company's ability to measure roofs. Then I found this app and it does everything I need it to do for free. The measurements are VERY precise. I've ordered 100's of Eagleview Aerial reports with measurements in the past and have measured many of them with this app as practice to see how close I can get to their measurements and they are right on the money most every time. I'm not even sure what all else this app has the ability to do but for what my company and I need, it is perfect. Awesomess!!! Love it!
