This app is a portable metal detector. By detecting nearby electromagnetic fields using the phone's 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 magnetic 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.

Pleased Former Skeptic

Pros: Works, free, no obnoxious adds, phone case doesn't disrupt the app
Cons: none

This app really works, I even had a case on my phone and got much higher readings on/near metal than on a jacket or my leg etc. And the results aren't random thy show a difference in number reading by the hundreds and stay at the same (fluctuating between a numbers or two up/down) reading for the same spot. Other apps were deceiving because the numbers would just randomly switch up or not correlate logically!

Actually works.

I figured this was a gimmick but tried it anyway and managed to find the four corner pins to my property. They were buried about 4 inches in clay and I was holding it about an inch from the ground. Also managed to find about a 6 inch piece of rusty barbed wire buried about 5 inches deep. Not sure how close you have to be but as long as you are close, this can pinpoint what you're looking for. What I was looking for/found was iron, haven't tried any other metals.
