HOW IT WORKS
By detecting nearby electromagnetic fields using the phones built-in magnetometer/compass, you can locate nearby metal and magnets. You can also use it to find metallic studs and wiring behind walls. Works with only ferromagnetic metal (steel, iron etc).
The magnetic field level(EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. You will see this value by default.
Best sensitivity near the camera on your iOS device. Shake for calibration.
