EFM Discovery

Application that allows you to detect the natural magnetic fields and those produced by various devices.

Taking advantage of the hardware of your phone the application detects magnetic fields (microTesla or Gauss depending on the unit of measure desired).

So you can measure the magnetic field generated by a device or present in your homes.

And for not to miss any survey you can enable an option to keep the screen always active.

PS: For those of you fans of "Ghostbusters", following the theory that the presence of high magnetic fields favors their presence is possbile to turn on or off the torch by clicking the appropriate button called up from the menu (you never know whether you want a little light in those moments).
