Electromagnetic Ouija Board - converts electromagnetic vibrations into letters.
This application, using a magnetometer, converts electromagnetic waves around your device into letters of the Latin or Cyrillic alphabet, thereby acting as an analogue of the Ouija board, only without a board and a tablet.
It should be borne in mind that for the application to work, you need your device to have a magnetometer. It can also be assumed that this method of communication is unusual for spirits, and it is worthwhile to figure out how to influence the device in order to extract exactly the letters that are needed.
The sensitivity control is needed to set the accuracy - the higher the slider, the less interference, and the more difficult it is for the spirit to influence the device.
This app is intended for paranormal researchers, ghost hunters and simply enthusiasts seeking to connect with the spirit world.
