Ectograph
Something in here is listening.
A spirit box that runs on your phone's real sensors. The readings decide when a word comes through, and which one.

See it working
Three screens from a real session.
The sensors choose the words
Every word can be traced back to a reading.
The sensors watch
The scan zeroes every channel on the room. That baseline is what quiet means.
The scan detects a change
A hard swing away from the baseline lets a word through. A quiet room stays a quiet app.
The reading picks the word
The disturbed reading picks the word. It is not a random draw.
Using it well
A spirit box is an instrument. Treat it like one.
Keep the phone still
Movement swings the motion sensors and forces false words.
Stay clear of electronics
Speakers, magnets and large metal push the magnetic field around.
Ask, then wait
Nothing comes through until a sensor moves, so a quiet spell is normal.
Trust the transcript
Review the saved session, not what you think you heard in the dark.
