This app measures magnetic field with an embedded magnetic sensor.

"Usage is simple: Open the app, and move it around. The magnetic field level will constantly fluctuate. That's it!

You can find electrical wires in the walls (like a stud detector) and iron pipes in the ground.

A lot of ghost hunters had downloaded this app, and they had experimented as a ghost detector.

The accuracy depends entirely on your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, PC, microwave) due to electromagnetic waves.
