Works perfectly!

For what I needed it for, finding studs in a wall, it works perfectly. I had drilled a handful of holes in my walls to hang a shoe rack using the sound method (change in sound throughout the wall to locate studs) and failed miserably. I was about to go out and buy a $15-30 stud finder when I got curious and went to go download this app to give it a go. Works great, tested it on common household stuff to check reliability and hasnt let me down yet. Great free tool to have.
