GHOST SCOPE: Camera & Box

GHOST SCOPE is an entertainment app for people who like the atmosphere of a night investigation. It does not detect ghosts, and it never pretends to.

Everything it shows you comes from your own device. There are no scripted scares, no random jump events, and no hidden sprites waiting to appear. If a box is drawn on screen, something in the camera image actually changed.

■ GHOST CAMERA

Point the phone at a room and the app compares each frame with the last one. Where the image genuinely changes, it marks the region, traces its outline, and gives it a score.

• Gyroscope compensation, so the app can tell your hand moving from the scene moving
• A watch mode that becomes far more sensitive once you put the device down
• Seven sensitivity steps, because a grainy room and a still one need different thresholds
• Capture the screen with the overlay drawn on it, straight to your gallery

■ GHOST BOX

A scanning band built entirely on your device, from noise and from speech fragments your phone's own text-to-speech engine synthesises. Words surface through the band and are written down with the time they were heard.

• A waveform that draws the sound actually leaving the speaker, not a decorative animation
• Adjustable scan speed and volume
• Run it beside the camera and it speaks more often while the camera is picking something up

■ RECORDS

Photos you capture and sessions you save are kept together in time order, each with the coordinates where it happened — so a visit to one room stays one story. Everything stays on your device.

■ HONEST ABOUT THE METHOD

Tap the question mark beside either feature and the app explains, with diagrams, exactly what it is doing: frame difference, stabilisation, persistence checks, outlines, band scanning, fragment shaping. No mystery, no invented science.

■ PRIVACY

No account. No analytics. We run no servers and receive nothing from the app. Camera frames are processed in memory and discarded. Location is optional, read only while a screen is open, and never transmitted. English and Korean throughout.

For entertainment purposes only. This app analyses a camera image and generates sound. It does not detect ghosts, spirits, or any paranormal phenomenon, and nothing it displays should be taken as evidence of one.
