Turns your cell phone into a metal detector.

This app measures nearby electromagnetic fields using the phone's built-in magnetometer compass. The magnetic field level in nature is about 30~60μT. If there is any metal in the area, the strength of the magnetic field should increase.It is possible to detect the metal in such principles.

How to use:

Open this app on your device, and move it around. The magnetic field values will constantly fluctuate. That's it!


Enjoy!
