Thank you for the detailed feedback. The app detects the metal screws and nails that fasten the stud rather than the wood itself — and those fasteners are spaced along the stud, so a single spot may show nothing even directly over it. Scanning slowly and checking 30–40 cm above or below the same line usually reveals them. Calibrating away from metal objects and raising the sensitivity also improves detection.
Yay

Sorry to hear it didn't detect anything for you — that's almost always fixable. The app senses the metal screws and nails inside studs with your iPhone's magnetometer, so it helps to calibrate away from any metal, hold the phone flat against the wall and scan slowly; raising the sensitivity helps on thicker walls. On lath-and-plaster walls detection is naturally weaker. Give it another try with these steps — we'd love to change your mind.
