Your iPhone can use the magnetometer to mesure the magnetic fields when placed near a feromagnetic metal like iron, silver, stell! Try it, it's huge.
Amazing ... your friends will not believe it !
Try it, you will be blown away by this application.

To all the skeptics, this does work. However not for real world application, as you have to place it pretty close to the metal to even get a change in numbers. Default is about 43. Fun to play with. Want real fun, get a real metal detector.
It's ok but I wouldn't recommend it…
It works sometimes. I believe you should try it but it doesn't work all the time. I put a metal spoon in front of it and it worked, but when I did it again nothing happened. This app is ok.
I took a metal spoon and put it near the lens of my iPad and it beeped and said metal is detected and I took the spoon away and used other metal and nonmetal things and it works please download this app!
