Metal Detector apps require a magnetic sensor (magnetometer). If this app does not work properly, please check the specifications of your device.
This app measures the magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(Milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, the magnetic field level will increase.
Usage is simple: Open the app, and move it around. The magnetic field level will constantly fluctuate. The higher the value implies more metals nearby. That's it!
The accuracy of this detector app is totally dependent on the magnetic sensor (Magnetometer) in your smartphone and it is mostly affected by electrical equipment such as computers, TV, etc due to electromagnetic waves.
You can find electrical wires in the walls (like a stud detector) and iron pipes in the ground or even useful to find a lost needle or screws.
