Works great – Free Metal Detector - Stud Finder and EMF Meter in One! Review

The app is works great at detecting metal objects. You need to understand that the app is looking for the metal screws or nails used to hang Sheetrock not an actual wood stud. The nails or screws can be spaced a foot or more from each other so it might take a little searching to detect one.
