Pocket Medium uses your devices magnetometer as an EMF detector, except this app uses the magnetometers X, Y axis as EMF Buttons, so unknown entities can write messages. +X to ascend letters.-X to descend letters.+Y to add letter to board.
If your device doesnt have a magnetometer the program wont work.
Future updates and features comming soon.
I started this project with this hypothesis in mind: Are ghost actually using EMFs to communicate with us using EMF detectors?
With this program we can all find out the truth.
