Find magnetic field generating objects with your device! The app works thanks to device's built-in magnetometer! The sensor allows you to detect objects generating a magnetic & electromagnetic field like electronic devices (phones, wiretaps), sharp objects, metal screws, wires and much more!

The app is perfect for:

Construction workers & handymen ->
- to find where in the walls are hidden wires
- to determine the location of metal framing studs

Students ->
- for educational purposes like school projects and experiments

Please note that Magnetic Detector PRO is not a replacement for professional metal detector devices and it should be used for private/entertainment purposes only.

Pretty neat!

So I was using this as kind of a stud finder. It’s tricky but it does find them for the most part (FYI not the wood of course). You want fancy get walabot. This is good. 1 Star off because of that god Sergio beeping without detecting anything (and yes u can disable the sound)

Needs user controlled sound threshold

One of the better mag field detector apps. As it is now, the sound is either on or off. It would be much more useful if the user could configure the threshold at which the sound comes on, which would make it configurable as an alert as well as a simple audible field strength indicator. Hope the developer can give us that feature in the future!

I’m not entirely sure just WHAT it’s actually detecting (hey, I’ll admit I’m not a genius on this topic... yet*g*) but I know enough about magnetic fields to realize that they’re something we should be aware of. The app is really simple and very consistent. Plus, it’s great fun to play with 😎.
Now I just need to figure out why my iHome alarm clock/stereo system pegs the meter off the charts while my 16 plug surge protector barely registers! LOL
