Ghost Hunting EMF & Ghost Box
$9.99 · Designed for iPad. Not verified for macOS.
Open the channel. Listen for voices in the noise. An ITC spirit box for EVP sessions and paranormal field work.
Necrophon is an ITC audio tool for paranormal investigation, designed for spirit communication, EVP sessions, and experimental field work.
It combines randomized phonetic audio banks, live audio processing, and environmental sensor readings in a focused investigation experience.
AUDIO-BASED SPIRIT COMMUNICATION
Necrophon generates a continuous stream of randomized audio fragments rather than playing scripted responses. Its sound banks contain phonemes, partial vocal sounds, reversed material, foreign-language fragments, whispers, granular textures, drones, and other noise elements designed to create an evolving voice-like audio field.
The audio is dynamically layered and processed during each session, so the sequence is continually changing. Listen for words, names, or phrases that may emerge from the sound field and interpret them for yourself.
8 SOUND BANKS
• Phonemes
• Reversed
• Foreign
• Whispers
• Granular
• Drones
• Noises
• Noise Bed
An optional white-noise bank provides an additional sound source for EVP and ITC sessions.
DYNAMIC AUDIO
Necrophon continuously varies the balance and timing of its sound banks rather than following a fixed sequence. Short bursts can emerge from quieter periods, creating a changing and unpredictable listening experience.
Live echo and reverb controls let you shape the character of the audio during a session.
BUILT-IN EMF & MOTION READINGS
Monitor environmental activity alongside the audio.
The built-in magnetometer provides live magnetic-field readings, while motion and rotation sensors can display movement and orientation changes during an investigation.
Use the readings as additional environmental information while conducting your session.
SESSION RECORDING
Record your investigations directly in the app and replay them later from the built-in session archive.
Recordings remain on your device.
DESIGNED FOR PARANORMAL INVESTIGATION
Necrophon combines an ITC-style audio experience with environmental sensor readings, session recording, and live audio effects in one tool.
Use it for:
• Spirit communication sessions
• EVP experiments
• Ghost hunting
• Paranormal investigations
• ITC research
• Field recordings
• Audio-based paranormal experiments
NO ADS. NO ACCOUNTS. FULLY OFFLINE.
Necrophon works without an account and does not require an internet connection for its core functionality.
The app is intended for entertainment and experimental paranormal investigation. Its audio is generated from randomized sound fragments, and any words or messages perceived within the audio are subject to personal interpretation.
