Ghost Frequency: Spirit Box

Turn the radio dial and tune the frequency.
Between the crackling static… something might answer.

Ghost Frequency lets you try the tools ghost hunters use — a spirit box, an EMF detector and EVP analysis — all on your phone.

■ Frequency (Spirit Box)
- 60–108 MHz radar dial and resonance meter
- Find the daily "resonance frequency" — the stronger it is, the more often they answer
- Special frequency 66.6 MHz
- Wandering spirits · Old spirits · Lost Spirits who answer in English

■ Summoning
- Pick a question and hear whispers, knocks, footsteps, creaking doors, breathing, bells, a music box, chains or words
- As spirit energy rises, a heartbeat kicks in and the screen shakes
- Candles, fog, shadows, CRT scanlines · flashlight blinks · vibration
- Much more intense with earphones

■ Detector (EMF)
- K-II meter that measures real magnetic field changes with your phone's magnetometer
- Tune the radio straight to the ENTITY frequency caught on the radar
- Geiger counter clicks · alarm and flashlight blinks on strong spikes

■ EVP Lab
- Replay past sessions and "decode" them
- Noise gate · low voice · reverse playback (backmasking) · 0.5x speed
- Export as an audio file (WAV) to share with friends

■ Spirit Codex
- Summon at certain frequencies to record the spirit dwelling there
- 10 spirits with danger levels and hidden-spirit hints

■ Safety Ward
- 3-minute auto end; turn off sound effects, vibration, flashlight and screen flashes
- Scared? "Cut all connections now" stops everything instantly

※ Ghost Frequency is a horror experience app for entertainment. Sounds and words are pre-made by the app and played at random; it does not detect or summon real spirits or supernatural phenomena. Magnetic readings are real values from your phone's sensor, but interpreting them as spirits is part of the show.
※ Contains sudden sounds, vibration and flashing light. Please don't use it if you're sensitive to scary content or flashing lights.
