Ghost Detector is an application that uses your mobile device sensors to detect sources of variable magnetic emissions. Which could indicate us the presence of some kind of paranormal activity. Ghost Detector is the only app that shows the distance between the paranormal activity and you. Also shows the magnetic field variations. It will not show magnetic fields at constant frequencies such as those generated by electronics, for example: TV, routers, computers, chargers, mobile phones, etc. The application will show a green dot on the radar in case there is nearby a source of magnetic emission. The detection range varies between 0 and 30 feet approximately, depending on the mobile device used.
