Use this simple app to detect electromagnetic fields, metals, devices and amaze your friends with what your phone can do. Watch out because some people believe that sudden changes in the EM field might indicate the presence of paranormal entities :p.
The new themes offer the user greater accuracy, graphs of the displayed readings and even the ability to calculate and show the auxiliary field H which is calculated from the magnetic field. The simple theme makes it easier for inexperienced users to measure and study magnetic fields.
This app uses the magnetic sensor(compass) of your phone and displays the reading with a line of LEDs and a classic needle meter. You can switch between units of measurement (uTesla and Gauss) and change the range of measurement from the settings.
You can use this app to measure and study magnetism and electromagnetism, the earths geomagnetic field and more.
