GhostScope, the ghost-hunting kit that says what is real

What can you do with GhostScope?

Read the magnetic field

The EMF Meter shows the strength of the magnetic field around the phone, 20 times a second, as a big number in µT or mG. A 5-LED bar, a ring gauge and a live graph of the last 6 seconds make changes easy to see, and PEAK, LEVEL and EVENTS keep score while a hunt runs.

Tap Calibrate to set the current reading as zero, so the meter shows only what changes from there. Any reading at or above your spike threshold (80 µT by default) is logged as an EMF Spike with a vibration and, if you want, a short sound.

Record and replay EVP

The EVP Recorder records the microphone to an audio file on the device, with a level ring and a timer. Afterwards you can play it back anywhere from 0.25× to 2.00×, or jump straight to half speed with ½x.

Play with the radar and the pendulum

The Spirit Radar is an animated sweep with blips at random positions: a visual effect, and the screen says so. The Pendulum answers YES, NO or MAYBE from how you tilt the device for 8 seconds.

Keep a log of each hunt

Tap End & Save Session and the hunt goes to the Hunt Log with its duration, peak reading, number of samples and every event: spikes, your marks, EVP recordings and pendulum questions. The log keeps your last 100 hunts.

Quick start

1. Open GhostScope and tap the EMF Meter tile.
2. Tap Start Hunt. The number starts moving and the LED bar lights up.
3. Hold the phone still for a moment and tap Calibrate, so the room's normal field reads as zero.
4. Walk slowly. Tap Mark whenever something happens that you want to remember.
5. Record an EVP from the EVP Recorder tile if you like; while the hunt runs it is added as an event.
6. Back on the meter, tap End & Save Session, then open Hunt Log to review it.

Free, and what Pro adds

GhostScope is free to download and shows ads. The EMF meter, calibration, spike alerts, Spirit Radar, Pendulum, Hunt Log and one EVP recording per day are free; watching an optional ad gives one more recording.

GhostScope Pro comes as a weekly, monthly or yearly subscription or a one-time Lifetime purchase. It adds unlimited EVP recordings, export of a recording as an .m4a file, a sensitivity boost above ×1.4 (up to ×2.0), and no ads. The export is the one most people end up wanting: the free tier loses an EVP clip the moment you leave the screen, which is its biggest limit.

Privacy, offline use and permissions

• No account and no sign-up. Readings, hunts and recordings stay on your device.
• The meter, recorder, radar, pendulum and log work without a connection. The free version uses the internet for ads, and purchases go through the App Store.
• The microphone is asked for only the first time you record an EVP.
• Tracking permission is asked for ads; if you decline, the app works the same and ads are not personalised.

What it cannot do

No app can detect ghosts, and GhostScope does not claim to. The phone's compass sensor measures magnetic field strength, not electric fields, Wi-Fi or cell signals, so its numbers will not match a handheld ghost-hunting meter. There is no location, photo, temperature sensor or spirit box in the app, and it runs on iPhone and iPad only.
