Most ghost apps guess. Watcher measures.
Watcher turns your iPhone into a multi-sensor field instrument for paranormal investigation. It reads the microphone, magnetometer, motion sensors and barometer in real time, rules out the ordinary explanations first — electrical hum, machinery, chargers, doors, your own movement — and shows you what’s left.
SENSE WHAT YOU CAN’T
• Live spectrum — watch sound from deep bass up past the limit of human hearing
• Ultrasonic detection — catches tones and bursts above 18 kHz, and flags steady tones that are likely electronics
• Infrasound — low-frequency energy and its dominant frequency, including the 17–21 Hz range
• EMF — magnetic field shifts against a self-calibrating baseline
• Barometer — sudden air-pressure changes from doors, drafts and vents
• RNG field — statistical randomness tests on your device’s entropy source
RULE OUT THE ORDINARY
Watcher doesn’t shout “activity” at every noise. It recognizes 50/60 Hz electrical hum and mechanical sources, ignores readings while you’re moving the phone, recalibrates when you start charging, and learns each location’s normal baseline. Every reading shows what was explained away and what remains unexplained.
A SPIRIT BOX WITH NOTHING TO HIDE
No timers. No endless stream of random words. Press START and Watcher listens in silence — it speaks only when a sensor registers a real event: a magnetic shift, a low-frequency surge, an ultrasonic burst, a pressure change, or a sharp rise in unexplained activity. Your own voice doesn’t trigger it.
• Each word is selected by the live sensor readings at that moment — not by a software random number
• Every word shows what triggered it, so you can judge it for yourself
• SCAN — a 15,000-word dictionary
• EVP — short call-and-response words, listening for a reply after each one
• NAMES — over 1,700 first names from 1880 to today, for asking “what is your name?”
When unexplained activity reaches contact level, the channel opens on its own.
DOCUMENT EVERYTHING
• Every investigation is a recorded session, tagged with a location
• Session summaries with peak readings and time in contact
• Learned baselines for each place you investigate
• Full CSV export of sensor readings and every word, with its trigger and timestamp
YOUR DATA, YOUR DEVICE
Everything happens on your iPhone. No account, no ads, no tracking, no network connection. Audio is analyzed in fractions of a second and never recorded or stored. Session and word logs are kept for 30 days, then deleted automatically. Total storage is capped at 50 MB — typical use is well under 1 MB per day — and the current size is always shown on the main screen. Export anytime to keep a permanent copy.
Grab your phone, choose a location, and find out what’s really there.
