Metal Detector is an online application that provides the measurement of the magnetic field - as long as you have a magnetic sensor (magnetometer). The app can be used to find the direction of a place or object with an embedded sensor.

This app is also used to find hidden electrical wires within walls, as well as iron pipes within the ground. If you have a strong 12th house placements, or abundant ones, you can use this app as a ghost detector - and satisfy this particular aspect of yourself.

Other features include an alarm, a beeping sound, the option to switch the sound effects on or off, and more.
