    Have seen some Metal Detector apps. Can this be true? Does it work? Or are they just for fun? :thinking:

    I find it highly unlikely that a phone can be used as a metal detector lol

    haven't actually tried one of these apps but am an engineer who works with industrial metal detectors in the food industry, they work on the principle of balanced magnetic fields, the presence of metal upsets the balance and triggers an alarm so its quite probable a smart phone may be able to do a weak version of this, just know i dont want food reaching my table knowing my desire has checked it:)

    I tried one for a laugh. As has aslready been stated they use the phones internal magnetometer (that it uses for compass bearings).
    It worked, sort of, but it's really just a gimmick - nothing useful.

    I tried myself and had no big success. It seems working but after a while it goes crazy. Never mind.

    Thank you all for your replies!
