SpectraSentry Tactical Skanner
A macOS (Apple Silicon) spectrum analyzer and paranormal-investigation suite built for real fieldwork — RF waterfall and 3D spectrum, SDR radio, ADS-B aircraft radar, Digital-TV RF Vision, EMF HUD, EVP audio, and a full paranormal toolkit.

Every display shows real data
Every display shows real data captured from connected hardware — there is no demo mode and no synthesized readings. When no supported device is connected, the app says so and lists the hardware it needs.
SpectraSentry Tactical Skanner
High-resolution spectrum analyzer with a 60 fps waterfall, 2D/3D spectrum and live-trace displays, SDR radio, ADS-B radar, Digital-TV RF Vision, EMF-390 HUD, audio/EVP monitoring, frequency generation, TSCM rogue-device detection, a vision-camera suite, and an investigation-profile system.
SpectraSentryOmeter
Companion environmental monitor. Reads temperature, EMF, barometric pressure and humidity from real CoreBluetooth sensors, flags paranormal-range anomalies, and cross-correlates environmental events with RF anomalies over an IPC bridge.
Twelve instruments in one suite
Each feature has its own guide — what it does, what it is for, how to use it and full specs.
ADS-B Aircraft Radar
A 1090 MHz Mode S receiver and PPI radar that tracks real aircraft — CRC-validated decodes only, nothing simulated.
Learn moreAudio Monitor & EVP
Real microphone capture with a 64-band FFT analyzer, infrasound detection, and a dedicated EVP session recorder.
Learn moreDigital TV & RF Vision
UHF/VHF channel scanners for ATSC (US) and DVB-T/DVB-T2 (EU), plus RF Vision — a live raw-IQ visualization of RF energy through ffmpeg.
Learn more3D Surface & Live Trace
Two more ways to look at the same real sweep data — an orbitable 3D spectral surface and an oscilloscope-style live trace.
Learn moreEMF-390 Tactical HUD
Full multi-sensor polling of the GQ EMF-390 v2 — EMF, Electric Field and 3-axis gyro — with severity-coded gauges and real serial readings.
Learn moreFrequency Generator
A tone and waveform generator for field work — Solfeggio, Schumann, brainwave entrainment, binaural beats, noise and sweeps.
Learn moreParanormal Investigation Toolkit
A suite of investigation tools — Ovilus, REM-POD, Cold Spot, Tesla Field, Laser Grid and Geophone — every one driven by real sensor, audio or camera input.
Learn moreInvestigation & Skanning Profiles
One-click presets that configure devices, displays, sweep ranges and alert thresholds for a scenario — including a dedicated Skinwalker Ranch mode.
Learn moreRF Spectrum & Waterfall
An AirSpy/SDR#-style stacked view — a live 2D spectrum directly above a frequency-aligned waterfall — the default landing display for real RF analysis.
Learn moreSDR Radio
A vintage-dial AM/FM receiver driven by the RTL-SDR, with 20 presets, an FM auto-seek scanner, squelch, and a real power toggle.
Learn moreTSCM Counter-Surveillance
Sweep for covert cameras, wireless microphones, evil-twin WiFi and rogue Bluetooth — from real scans and sweeps, matched against frequency and vendor databases.
Learn moreSLS / XLS Vision Cameras
Real camera capture with Apple Vision body-pose and stereo depth, plus ~20 selectable vision modes over the live feed.
