True EMF Detector is an Electromagnetic-Field (EMF) detector app that uses the built-in magnetic field sensor of your device to show the data received from it on a LED indicator display and a graph that updates in realtime. It also includes a flashlight button to quickly use the flash to see around in the dark.
True EMF Detector does not alter or modify the readings received from your phone's hardware in any form, showing you the true, accurate and un-altered values of the magnetic field strength around your phone.
This app can be used to look for the presence of paranormal entities assuming that: They exist; and they give off electromagnetic field (EMF) fluctuations in the surroundings. The on-screen flashlight button provides an easy way to access the flash or torch to look around in the dark.
