Turn your device into a professional-grade paranormal investigation toolkit, wrapped in a tactile Liquid Glass interface and powered strictly by authentic hardware sensors with zero simulated data. CORE CAPABILITIES • Tactical HUD & Live Filters: Overlay telemetry onto your camera feed and toggle real-time visual modes, including Thermal Ironbow, Night Vision, Full Spectrum, and Motion Delta. • MultiMeter Fusion Console: Watch all 8 sensors at once on one master screen, with a picture-in-picture camera and synchronized multi-track recording. • Dual-Camera & 3D Spatial Meshing: Monitor environments simultaneously with front/rear feeds, dual-camera stereo depth, and LiDAR/TrueDepth 3D spatial surface meshes and point clouds, sharpened by live depth upscaling up to 4×. • Hands-Free & Physical Triggers: Start captures and log anomaly tags instantly using Camera Control, the Action Button, physical Volume buttons, or Siri Shortcuts without looking at your screen. • Live Sonification & Captions: Acoustic sonification translates telemetry anomalies into pitch cues and Geiger clicks, paired with live captions for silent or low-visibility vigils. • Crash-Resilient Recording: Capture video, audio, and high-frequency telemetry with continuous disk streaming and intelligent thermal power management. INTEGRATED SENSOR SUITE • SLS & Depth Camera: Real-time AI skeletal tracking for people, dogs and cats up to native 4K and 240 FPS slow-motion, continuous 3D surface reconstruction, facial landmark mapping, and stereo low-light boost. • 5-Sensor ITC & Interrogation: Correlate simultaneous environmental deflections across EMF, Barometer, Light, Motion, and RF into natural-language translation rationales. • EVP Recorder & Carrier Waves: Live spectrogram, multi-engine speech transcription, anomaly markers, and multi-spectrum acoustic noise generation (White, Pink, Brown). • EMF Detector: 3-axis electromagnetic monitoring with K2-style meters, directional radar, and dynamic graph views. • Motion & Seismograph: High-sensitivity G-Force impact and vibration detection with rapid TARE baseline calibration. • Barometer, Light & RF Scanner: Real-time ambient Lux tracking, atmospheric pressure shift detection, and spatial 2.4 GHz BLE radar mapping. PRO EVIDENCE LAB & FORENSIC ANALYSIS • Synchronized Telemetry Playback: Replay footage with interactive 360° Vector Radars, K2 meters, Geophones, and rolling spectrograms synced down to the millisecond. • Precision Inspection Engine: Inspect captures with exact frame-by-step pads, post-capture tracking model comparisons, interactive depth filters (Silhouette, Contour, Point Cloud), and full video tuning. • Universal Media Import: Load pre-recorded video or extract Live Photos directly from your Files app or Photos Library with automatic orientation correction. • Multi-Format Forensic Export: Burn active visual filters and tracking wireframes directly into MP4 video, export universal 3D models (Apple USDZ / Stanford PLY), or package raw metric depth streams and synchronized CSV logs into ZIP case archives. • Investigator Dossier & Achievements: Review field career statistics, unlock 53 tiered paranormal trophies, and verify milestones on global Game Center leaderboards.

HauntKeep turns your phone's real sensors into a kit of paranormal investigation instruments: SLS, an EMF meter, a spirit box, an EVP recorder, a vibration geophone, and more. Built for atmosphere, curiosity, and a good scare. Every reading has a source, and the app shows it. A number on screen traces back to a sensor in your phone, with the steps behind it on the same screen: the live input, the baseline it is measured against, and the math in between. Values the app fetches or works out are labeled that way: the day's space weather and local conditions are fetched, and the moon phase is worked out from the date. A mode that needs hardware your phone doesn't have says so and stops. What a reading means is yours to decide. Every mode says which kind it is: REAL for the ones that measure a physical signal, EXPERIENCE for the ones built for mood and story, on the tile, before you open it. Both kinds show their working. THE INSTRUMENTS: each reads a sensor on your phone • EMF Meter: your phone's real magnetometer, with a live baseline, a standard-deviation gauge, and space-weather (Kp) context so you can see when the field leaves your room's normal. • EVP Recorder: records the room to WAV with markers, then plays it back with a waveform, spectrogram, variable speed and a high-pass filter. • Sound: a live level meter and FFT spectrogram of the room. • Vibration: a geophone that turns your accelerometer into a seismograph for taps and footsteps. • Shadow: place your phone and watch for luminance and motion changes. • Dowsing Rods: two rods swung by real changes in magnetic heading. • Vision: a low-light camera enhancer. • SLS: a pose-estimation skeleton overlay on the live camera. THE EXPERIENCES: interpretive, and each names what drives it • Dictionary: a word engine driven by live field readings. • Phonetic (Spirit Box): a synthesized voice sweep; the field sets how busy it is, and the words come from the app's own bank. • Radio Sweep: a sweep across live internet radio. • Music Box, Morse, REM Touch, Talking Board, Draw, White Noise, and a live multi-sensor Investigation camera. SESSIONS • Record a baseline sweep so spikes are measured against your room's own normal. • A cross-mode timeline lines up every mode's events on one ruler and flags moments when two or more independent sensors fire within the same 2 s window. • Tag a session with real environmental context: weather, sunrise/sunset, moon phase, and the space-weather Kp index (optional; uses approximate location). • Export a session as a clean report or a shareable zip. PRIVATE BY DESIGN • Yours alone: no accounts, no ads, no trackers, no analytics SDKs. • Your recordings, photos, and notes stay on your device. • The one thing that ever leaves your phone is an approximate, rounded location, sent to a weather service when you tap to add environmental context. • Deleting the app removes all of its data. FREE TO EXPLORE Free to install, with the EMF meter and the Talking Board fully open: no time limit and no ads. The whole investigation layer is free too: sessions, the baseline sweep, the cross-mode timeline and environmental context. One optional purchase opens the remaining modes and lets you take a case file away: PDF reports, session bundles and CSV export. Pay once; there is no subscription. WHAT TO EXPECT The instruments read your phone's real sensors, and every value arrives with the steps behind it. HauntKeep is an entertainment app, not a scientific, medical, or safety instrument, and it makes no claim about what its readings mean. What those readings mean is left entirely to you. It contains paranormal and mild-horror themes and is intended for a general (not young child) audience. Grab a friend, turn out the lights, and go ghost hunting.
