GhosthoundField
Read full descriptionHide 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.

Q3 Meter™ Mk2 is a professional electromagnetic field detection instrument built around live magnetometer measurements, three-axis field magnitude vectors, entropy mapping, and a four-variant Geiger-style pulse audio system synchronized with detected microtesla changes. The familiar five-indicator layout preserves the visual language paranormal investigators have used for years while replacing canned meter behavior with genuine sensor-driven instrumentation. Every indicator threshold, sweep animation, visualization event, and audio response is driven by changing field conditions and live CPI Engine output. The Geiger audio system dynamically selects from four response types — Soft Click, Hard Click, Decay Tone, and Resonant Pulse — based on the characteristics and intensity of each detected field event. Rate limiting prevents excessive pulse stacking during periods of sustained activity. A central particle visualization display transitions through five live field states — Idle Glow, Particle Flare, Golden Orbital Ring, Fireburst, and Lightning Discharge — reflecting changing electromagnetic conditions in real time. Industrial Mode classification, Heartbeat idle behavior with randomized 7–15 second intervals, and entropy-mapped anomaly scoring complete the instrumentation suite. The field is real. The data is real. The instrument finally matches both. 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 clearest difference is price: GhosthoundField at Free against Q3 Meter Mk2's $9.99. Q3 Meter Mk2's advantage is iOS requirement (15.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
