Results depend on your phone’s magnetic sensor and the wall materials. Use the app as a locating aid and confirm before drilling or cutting. Two scans are free; Pro begins with a 24-hour full-feature trial.
Set the wall baseline
Establish the normal magnetic reading for that wall before looking for stronger metal signals.
Follow a clear score
A 0–10 reading and haptic feedback make likely fasteners or metal framing easier to recognize.
Level the finished work
Use the included precision level after locating the target and preparing the installation.
A guided scan
The app explains what the sensor is seeing.
Motion compensation, a wall-specific baseline, the signal score, and vibration feedback work together so the scan is easier to repeat and understand.
- Likely screws and nails
- Metal studs and plates
- Possible metal conduit
- Two free scans before the Pro trial
