No simulated signals. 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.

Two Integrated Applications

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 from the Skanner over an IPC bridge.

Core Features

RF Spectrum & Waterfall

AirSpy/SDR#-style stacked view: a 2D spectrum directly over a frequency-aligned waterfall. Selectable color maps, filled live trace, wheel/drag/Fit zoom, plus standalone 3D surface and live-trace displays, SVG export, and detachable pop-out windows.

SDR Radio

Vintage-dial AM/FM receiver on the RTL-SDR with FM/AM demodulation, 20 presets (NOAA weather, aviation, marine, ham, ISM), FM auto-seek scanner, squelch, and a power ON/OFF toggle — streaming never auto-starts.

Learn more →

ADS-B Aircraft Radar

1090 MHz Mode S receiver with a CRC-24-validated DF17 decoder. PPI radar with range rings and compass, chevron aircraft icons, zip-code / lat-lon centering, hexdb intel lookup, and emergency-squawk alerts. Only real, decoded aircraft are shown.

Learn more →

Digital TV & RF Vision

UHF/VHF channel scanners for ATSC (US) and DVB-T/DVB-T2 (EU) with real signal-quality and lock analysis. RF Vision renders live raw IQ through ffmpeg as a moving image of RF energy at the tuned frequency — a real RF visualization (not decoded programming).

Audio & EVP Monitoring

Real CoreAudio microphone capture with 64-band FFT analysis, 1×–64× waveform zoom, dB-calibrated peak/RMS meters, 19 Hz infrasound detection, and a dedicated EVP session recorder. WAV recording (16/24-bit) streamed to disk with alert-triggered capture.

EMF-390 Tactical HUD

Full multi-sensor polling of the GQ EMF-390 v2 — EMF (combined + X/Y/Z), Electric Field, and 3-axis gyro — with severity-coded gauges, statistics, a device detail panel, and a live configuration dialog. Real serial readings; "DISCONNECTED" when unplugged.

Learn more →

3D Surface & Live Trace

An orbitable OpenGL spectral surface (frequency × time × amplitude) with wireframe overlay, plus an oscilloscope-style live trace with 1×–64× magnification — both fed by the same real sweep data.

Paranormal Investigation Toolkit

Ovilus

Word generation driven by real EMF/EF deviations from the EMF-390 (deterministic, not random).

REM-POD & Cold Spot

360° EM field display with ATDD temperature history, and a cold-spot temperature/EMF correlator. Temperature comes from a real BLE sensor via the Ometer — never synthesized.

Geophone

Vibration monitor derived from real microphone low-frequency energy (footsteps, bumps, infrasound). No mic → "no sensor."

Tesla / Static Field

Static-field scan display for charged-environment monitoring.

Laser Grid

Camera-based laser-grid break detection using real frame differencing at grid intersections.

SLS / XLS Vision Cameras

Real AVFoundation capture with Apple Vision body-pose and stereo-depth. ~20 vision modes (thermal, UV fluorescence, night vision, orb-field, and more) over the live feed.

Every tool above operates on real sensor, camera, or audio input. With no hardware present, each shows a "no sensor" state rather than fabricated readings.

Frequency Generation

Tone/waveform generator (audio output): Solfeggio presets, Schumann resonance (7.83 Hz), brainwave entrainment, binaural beats, white/pink noise, and linear/log sweeps.

Learn more →

TSCM Counter-Surveillance

Spy-camera and wireless-mic band detection, Evil-Twin WiFi detection (duplicate SSID / security downgrade), rogue-Bluetooth with OUI vendor lookup, and known-bad surveillance-vendor matching — from real WiFi/Bluetooth scans and sweeps.

Learn more →

Skinwalker Ranch Mode

1.6 GHz anomaly watch, ground-radar low-band sweeps, 19 Hz infrasound monitoring, and Solfeggio/Schumann environmental stimulation — packaged as an investigation profile.
