Metal Detector is a classic "hey, check out what my phone can do!" app. It uses your device's in-built magnetometer to measure the magnetic field value around it. As the magnetic field level(EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss) with 1μT standing for 10mG, any metal objects in your vicinity will increase its strength.
Therefore, the app will be useful for finding electrical wires in walls (like a stud finder), iron pipes in the ground, or smaller objects such as coins. Treasure chests aren't completely out of the question, but your time will be better spent on actually making a fortune.
Using the app is way simpler than handling an actual metal detector. Simply open it and move your smartphone around, guided by the changes in magnetic field strength. Try to stay away from electronic equipment, as electromagnetic interference is still a big thing in tech.
Also, remove your phone's cover if it has any metal or magnets on it. If the magnetic sensor in your device is accurate enough, you might end up finding a rusty nail or two - you won't know until you try!
Metal Detector is completely free and available in Google Play.
