FREE DOWNLOAD — PAID SUBSCRIPTION REQUIRED ParaPulse is free to download. An active annual subscription is required to access and use the app’s investigation features. The subscription costs $9.99 per year and is purchased through your Apple ID as an in-app purchase. ParaPulse is a sensor-driven paranormal investigation tool created for ghost hunters, investigators, and anyone curious about unexplained environmental activity. Instead of displaying words using a simple random timer, ParaPulse continuously monitors supported sensors available on your device and establishes a live environmental baseline. When changes are detected, the app analyzes the activity and selects words from its built-in lexicon based on the measured sensor data. PARANORMAL INVESTIGATION SESSIONS With an active subscription, you can start investigation sessions and monitor environmental changes in real time. ParaPulse provides a clear visual interface designed for haunted locations, paranormal experiments, home investigations, and general exploration. SENSOR-DRIVEN WORD DETECTION During an active session, words are selected in response to measured changes in available sensor data rather than appearing solely from a random timer. Each result is connected to environmental activity detected during the session. LIVE SENSOR MONITORING View supported device sensor channels throughout an investigation and observe changes, movement, spikes, and patterns as they occur. SESSION HISTORY Save investigation sessions for later review. Compare detected words, sensor activity, timestamps, and other session details to look for recurring patterns. BUILT FOR PARANORMAL INVESTIGATORS ParaPulse offers a modern approach to paranormal investigation by emphasizing environmental sensor data, live monitoring, and documented sessions. Use ParaPulse for: • Ghost-hunting investigations • Haunted-location exploration • Paranormal experiments • Environmental anomaly monitoring • Spirit-communication experiments • Home investigations • Urban exploration Whether you are an experienced paranormal investigator or simply curious about what your phone’s sensors may detect, ParaPulse gives you a structured way to explore, document, and review your environment.

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.
