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!
