I was able to try out your app today. I'm happy to report there were no crashes on my Droid while using the software. The measurements however, were not correct. My "target" was a gate in my backyard. Approx. 30 feet from my patio where "a" pictures was taken. Moving to the left for "b" picture, as far as I could go in the confinement of my backyard (less than 20 meters), is the result of the incorrect measurement. I congratulate you on a your nice work. I do have some suggestions. Keep in mind these are suggestions and are in no way criticism. First would it be possible to have a toggle to switch from meters to feet. While most of the world does use the metric system, the USA does not. Perhaps showing the result as both feet and meters. Also, is there any way to reduce the distance for the camera shot "b". In an open field one can move in any direction 20 meters without issue. However, in confined areas such as city streets and the like, many times one cannot move 20 meters. Such was the instance in my case. I hope I was of some help. The good news, there was no crash, and I used the software to reconfirm the measurements twice.
