Good

This app found studs in the wall but I am not sure if it can tell the difference between a stud and a nail. It did twice within 10 minutes start going off nonstop for no reason while in the palm of my hand and I had to force quit. I wish it would tell you what it meant when it was 60ut, 120ut and 180ut ranges. A few days later immediately after launching the application it started going off in my hand twice in a row before I did anything. This bug has to be fixed. There needs to be a way it just stops going off as well. I have to force quit, that is no good.
