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.

Dead Channel is a spirit box instrument built around eight voice banks. Tap Start and they begin: broken syllables, breaths, and pieces of English words, deep men and high women, forward and backwards, a few at a time with silence in between. Ask your question out loud, then listen. When a longer, clearer word or a whispered sentence comes through, the phone taps once and the screen flushes red. • Eight voice banks, each with its own tone, played in clusters with silence between • Echo, reverb, and a white noise bed that dips under the voices • Sweep rate from slow and sparse to fast and crowded • Every session is recorded with the effects you used and saved to the Library • Works offline, with no account and no ads, and it never uses the microphone Every sound is free to try for 48 hours. After the trial, a single one-time purchase unlocks Dead Channel for good. There is no subscription. Dead Channel is an instrument. It plays generated audio, and it does not prove the paranormal. Some voices are generated with Piper from the LibriTTS-R corpus (Koizumi et al., CC BY 4.0).
