## What is Metal Detector?

Metal Detector is a portable metal detector. By detecting nearby electromagnetic fields using the phone's built-in magnetometer/compass, you can locate nearby metal and magnets. You can also use it to find metallic studs and wiring behind walls. Depending on your phone, you can use it to detect metals up to 30cm away, and magnets from far, far away! Note that household equipment like TVs, and computers or even your phone case can affect readings. You can set a threshold at which the phone will vibrate when a critical reading has been reached.
 
===How to use this app?===

Very simple, just move the app around and read the measurements, if the magnetic field readings go over a critical level, the phone will vibrate, meaning a ferromagnetic material is nearby.
