Are you looking for a way to detect and measure the presence of electrical and magnetic fields? Do you want to know what type of device is near you? Do you want to find out if there are any dangerous EMF waves nearby? If your answer is yes to any of these questions, then the EMF Detector and Meter app is the right one for you. This app will not only detect electrical and magnetic fields, but it will also show you the exact level of the field in mG (milli gauss). It uses the built-in magnetic sensor to measure the magnetic field strength. It has a very simple interface, and it is very easy to use.
