The PRO/donate version of the EMF Detector . The detector is as ACCURATE as the sensor of your device.

The Pro has:
-->No ads
-->Recorder to save data to text file for later use on a computer
-->3 sound alerts: Max, Spike and Radar
-->Vibration alert
-->Variable sampling rate
-->A few backgrounds and skins for the detector.

Both Pro and Free have:
-->Magnetic Field B in microTesla,Gauss and milliGauss
-->Recorder (in free version Recorder is unlockable for free)
-->Auxiliary Field H in ampere per meter
-->XYZ, max-min and graphs.
-->The classic emf meter with the needle and LEDs

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.

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.

You can use this app to measure and study magnetism and electromagnetism, the earths geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices and even (as some people believe) entities and ghosts.

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. Please uninstall the app and dont leave bad reviews.Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it. Use at your own risk. Thank you.<------
