Doesn’t Work
Response from developer
Sorry it let you down on that job. The app senses the metal screws and nails inside studs with the phone's magnetometer — calibrate away from any metal, hold the phone flat against the wall and scan slowly, and raise the sensitivity for thicker walls. Confirming a mark with a second scan 30–40 cm above or below makes results far more dependable.
Garbage app, don’t buy

Sorry the app didn't work for you. It senses the metal screws and nails inside studs with the phone's magnetometer, so calibrate away from metal, hold the phone flat and scan slowly. If you tell us what went wrong, we're happy to help.
Doesn’t work

Thanks for the feedback. The app looks for the metal fasteners inside a stud rather than the wood, so a calibration away from metal, a flat hold against the wall and a slow scan make the biggest difference. Raising the sensitivity helps on thicker walls.
Does not work!!!!
Response from developer
Sorry it took that long. The app detects the metal screws and nails in the studs, so start with a calibration away from any metal, then slide the phone flat and slowly across the wall with the sensitivity raised. Lath-and-plaster walls are the hardest case; on drywall the fastener line usually shows up within a few passes.
