A simple EMF detector! The detector is as ACCURATE as the sensor of your device.
Use this simple app to detect electromagnetic fields and metals 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 paranormal entities :p.
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.
NOTE that this app uses the magnetic sensor. If your phone doesn't have this sensor the app is NOT going to display any measurements. If you open the app and the readings are 0 it means that this app can't work on your phone. Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it. Use at your own risk.

Added help button and tweaked the LEDs to appear in sync with the needle.
Note that the needle is supposed to go beyond the grid for realism.
