Ghost Detector: Real EMF Meter

Every ghost app claims to find spirits. This one tells you exactly what it is doing. The Field dial is a real EMF meter built on your phone's magnetometer, zeroed to your room, with peak-hold and a microtesla readout. The radar and the whispers are seeded randomness. We say so, and we label the fiction as fiction. There is no microphone, no camera, no location. Two permissions in the manifest; check for yourself.

THREE INSTRUMENTS

Field - a real EMF reader. Zero it to the room you are in, then watch how far the local magnetic field moves from that zero, in microtesla, stronger or weaker. The dial runs 0 to 10 across 90 microtesla of movement. Hold it near a speaker, a fridge door, a laptop charger. Two phones in the same room will broadly agree about the Field. That is what makes it the real one. It works as a plain magnetic field detector too, ghosts optional.

Radar - a sweep with blips that appear and fade on seeded randomness, lightly flavoured by how you move. Walk slowly toward a blip from a standstill and it may draw closer. Two phones will not agree about the radar. That is also the point.

Whispers - one-line symbolic readings drawn on your phone from a finite, authored local deck. There is no question box, because there is no answer. They arrive as prompts for thought, not statements about you.

AN INSTRUMENT THAT KEEPS ITS WORD

The zero is yours. Set it with one tap, and it is held - the dial will not quietly walk your zero away while you watch. Leave it unset and the dial says so, and follows the room instead. A zero more than six hours old is discarded rather than reused, because a zero from another building would be a lie.

Peak-hold keeps the biggest change your phone has seen this session, so a moment you missed is still on the dial when you look back. Save an encounter to your journal, and share it - the card says what it is.

TAKE IT GHOST HUNTING

If you bring it on a ghost hunt, the Field dial is a genuine EMF reading of the room you are standing in. What that means is yours to decide. The radar and whispers come along as atmosphere, clearly labelled.

If you came looking for an EMF detector app with a real sensor, this is that. The ghost part is the fun on top.

FOR ENTERTAINMENT PURPOSES ONLY

Ghost Detector is a fictional instrument. It does not find, prove, or measure anything paranormal, and nothing in it is a scientific claim. The radar and the whispers are mostly random. Tap How It Works inside the app and see the whole trick.

PERMISSIONS

No microphone. No camera. No location. The app never asks you to grant anything at runtime.

What it declares instead is the plumbing that ads and purchases run on: internet and network access, an advertising ID, Google Play billing, and the background pieces the ad library brings with it. You can read the full list on this page before you install. Nothing leaves your phone except analytics and ad requests, and your journal stays on the device.
