Hey guys Since I work in construction, im always looking for cool tricks to do with my iphone. I got Sonar Ruler http://appshopper.com/utilities/sonar-ruler its neat and since it was in the top 10 paid apps i thought it might actually work. well it does but only against walls, very near, very low ambient noise. its fun but not worth it.
no... or you have to be in a totally quiet room with exact temperature measuring and extremely straight walls But it was fun to try it out, but I never got an accurate measurement with it.
