What it does

Emf Meter

Your magnetometer measures magnetic field strength in real time. The K-II style LED bar lights up on every spike. Real data, not random numbers.

Evp Recorder

Capture Electronic Voice Phenomena and play them back at 0.5x speed, the classic method investigators use to hear hidden voices.

Spirit Radar

A live sweep reveals nearby entities, biased toward the real magnetic spikes happening around you.

Pendulum

Hold your phone steady and ask yes or no questions. The accelerometer reads the tilt and answers Yes, No or Maybe.

Hunt Log

Every investigation is saved automatically: location, duration, peak reading and every anomaly event. Track your recurring hotspots. GhostScope Pro unlocks unlimited saved sessions, advanced sensitivity, audio export, custom pendulum questions, home screen widgets and removes ads. For entertainment purposes only. GhostScope does not claim to detect real paranormal phenomena.

Questions people ask about GhostScope

Does it actually detect ghosts?
No. It reads the sensors your iPhone already has — the magnetometer, the accelerometer and the microphone — and shows what they pick up. It is built for entertainment, and it says so when there is nothing to read.
Is the EMF meter real?
Yes. The figure comes from the phone's magnetometer, the same sensor the compass uses, in microtesla. A handheld ghost-hunting meter reads AC fields in milligauss, so the two will not agree — wiring, speakers and laptops all move this one.
Does it need internet or an account?
Neither. Every reading happens on the phone. There is no sign-up and nothing is uploaded.
What is free and what does Pro add?
The EMF meter, the spirit radar, the pendulum and the hunt log are free. Pro adds unlimited EVP sessions, sensitivity above x1.4 and m4a export of your recordings, and removes the ads.
Why does the radar show something in an empty room?
The sweep is biased toward real magnetic spikes, and no room is magnetically silent: wiring, pipes and appliances all register. Treat a hit as a reason to go and look, not as proof.
Can I keep the EVP recordings?
Yes. Every session is saved in the hunt log with its location, duration and peak reading, and Pro exports the audio as m4a so you can listen to it elsewhere.
