Ectograph: Ghost Spirit Box

Frumpets

About this app

We built Ectograph to report and use real sensor data, not invented readings. Take Ectograph into the basement, an empty hallway, or a building with no signal. This offline spirit box speaks single words and short phrases in whispered voices while real sensor data stays in view.

Ectograph is a ghost box for focused paranormal investigation sessions. Ask questions , and listen for a responses through the static.

SPIRIT-BOX RESPONSES

• Hear single words and short phrases in whispered voices
• Magnetic-field changes, motion, light, pressure, and other real sensor disturbances can trigger a spoken response at any moment.
• Turn spoken responses on or off, and use a response chime and haptic pulse to mark each response.

REAL EMF AND SENSOR READINGS

• Watch the EMF meter show magnetic-field deviation from ambient on an LED ladder with a microtesla readout. Use it as a live EMF detector while you investigate.
• Open the Sensors page for live accelerometer, magnetometer, gyroscope, gravity, pressure, proximity, and light readings, plus temperature and humidity where your device supports them.
• If your phone lacks a sensor, Ectograph marks it unavailable instead of inventing a number.

SESSION LOG AND FIELD USE

• Review a timestamped log of every session and its responses later. Clear the log whenever you choose.
• Use the optional location tag, off by default, to remember which attic, corridor, or house a session ran in and see the spot on a map on the session card.
• Use Ectograph alongside other ghost hunting tools at haunted locations, during a seance, or in an ITC-style session at home.
• Add it to a ghost hunting kit alongside an EVP recorder, an EMF meter, and a camera.
• For a spirit talker session, ask a question, watch the readings, and listen for a response.

ONE PURCHASE. EVERYTHING INCLUDED.

Pay once. No ads, no subscription, no in-app purchases, and nothing sold inside. Buy Ectograph once and keep every voice, feature, and word pack. No account, no sign-up, no cloud services. Every voice, word, and sensor reading works entirely offline in the field. The optional session map needs an internet connection only the first time it loads map tiles for a place.

Ectograph does not request contacts or microphone access. Location is requested only for the optional session tag. The tag is off by default, and session locations stay on your device.
