Well not sure if its actually picking up communications from the other side but it seems to be quite on target more times than not. I believe it works as the developer states, an algorithm that generates words based on electromagnetic impulses your phones sensors receive from the environment. Sure some of the words seem random however many can be clearly and easily related to the location and persons in the given location. I recommend trying it in a "haunted" location or a place suspected of being "haunted". Spooky stuff.
