Read full description

GhosthoundField is a field notebook for paranormal investigators who want a clean record instead of gadget theatrics. FIND A PLACE, THEN INVESTIGATE IT The Places tab lists haunted places near you: cemeteries, houses, roads, forts, ships and more. Search any city, filter by type and distance, or browse them on a map. Each place has its documented history from Wikipedia and Wikidata, with the source shown, and any folklore kept separate and clearly labeled as a story, not proof. When Ghosthound has published a write-up, tap Read on Ghosthound. Tap "Start investigation here" and Ghosthound Field opens a new case card with the site, town and coordinates already filled in. Save places you want to visit; saved places keep their history on your phone, so they work with no signal. LISTEN BACK TO EVPs Play recordings in the app with a scrubbable waveform, HIT markers, half-speed playback and looping. Start an investigation card for each case with the site, city, team, case type, reported activity, and whether you have written permission and consent to name the location. A pre-session checklist makes sure the basics are covered. During a session, log events as they happen. Each entry gets a timestamp, room and investigator. GhosthoundField records what your device can actually measure: barometric pressure, magnetometer readings (labeled as the compass chip they are, not an EMF meter), outdoor weather, moon phase, and the NOAA geomagnetic Kp index. Pair a Bluetooth environmental sensor to add indoor temperature and humidity. Capture evidence in the same case: • EVP sessions recorded as uncompressed 48 kHz audio, with live hit marks • Evidence photos, including ProRAW on supported iPhone Pro models • LiDAR room geometry and depth on iPhone Pro and iPad Pro, with a flag when a living person is in frame When you're done, export a package of notes, CSV, PDF, audio, photos and LiDAR files to share however you like. No spirit box, no fake thermal camera. If it isn't on your device or a Bluetooth sensor, it isn't logged as if it were.

Demonivox™ Mk2 is a real-time audio analysis and Instrumental TransCommunication research platform built for investigators who want greater control, deeper instrumentation, and more responsive field interaction than a conventional ghost box can provide. Two distinct spirit-radio systems power the core experience. Turing Radio draws from curated modern commentary, philosophy, and speculative material, while Levenshtein Radio is sourced from historical broadcasts, mythological narratives, and paranormal discussion archives. Audio is remastered to 432Hz and processed through live anomaly-detection systems designed to support experimental EVP and ITC investigation. The CogniSys processing panel provides control over cognitive sensitivity thresholds, Schumann Resonance reference injection at 7.83Hz, world-radio blending, and haptic responses synchronized with detected magnetometer anomalies. Six audio environments — Amazing, Mystical, Mysterious, Troubling, Forbidden, and Default — provide real-time control over reverb, echo, and pitch characteristics. Three precision pedal effects — Pitch Pilot, Reverberation Realm, and Trivibe Echo — provide additional session control and allow investigators to shape the audio environment dynamically during operation. The CPI Engine continuously evaluates live device magnetometer activity and produces a dynamic anomaly score displayed alongside transmission intensity on the Dark Skies Tripod Gate instrumentation panel. Demonivox™ Mk2 combines sensor data, real-time audio manipulation, anomaly scoring, and controlled spirit-radio processing into a single investigation platform designed for experimental field use. This is instrumentation. This is research. This is Demonivox™ Mk2. Not made for entertainment. Patent-pending EMF and cognitive phase instrumentation — USPTO Provisional #63/942,408 & #63/947,185. --- BONUS INSTRUMENTS — INCLUDED FREE EMF Entropy™ A physics-driven electromagnetic visualization instrument that applies real-time entropy mapping to live magnetometer data. EMF Entropy™ analyzes changing magnetic-field behavior and generates a continuously evolving waveform rather than displaying a prerecorded or randomly animated signal. A 7.83Hz Schumann Resonance reference is incorporated into the visualization system to give investigators an additional comparative reference during field sessions. Coherent, turbulent, and fragmented waveform behavior can be observed as environmental magnetic conditions change. On Site Metrics™ A location-aware environmental and astronomical intelligence panel providing investigation context including temperature, cloud cover, UV index, solar radiation, irradiance, sunrise and sunset, moonrise and moonset, moon phase, and lunar illumination percentage. Location is used for local environmental data requests and astronomical calculations. Investigation data is not transmitted. Both bonus instruments are included at no additional cost. This is instrumentation. This is research. This is Ghost Hunter Apps.

Verdict

The call

The clearest difference is price: GhosthoundField at Free against Demonivox Mk2's $9.99. Demonivox Mk2's advantage is iOS requirement (15.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
