Metal Detector: Find the metal and electromagnetic waves with your phone.
This metal detector detects magnetic field values using the magnetic sensors that is built into the phone.
The magnetic field level(EMF) in nature is about 49μT(microtesla) or 490mG(milligauss); 1μT = 10mG.
As soon as your phone approaches a metal, you will see metal detector's signal increasing.
Lost anything metal?
Trying to search someone's body?
That's a great tool.
If this app does not work properly, it may mean that your phone's sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern.
Sometimes a leather case with a magnetic "snap" can cause unwanted results. Remove the case to increase accuracy.
