A ghost-hunting app that doesn't invent the words.

Random selection creates activity. Fixed mapping creates a system.

Fixed vocabulary map

Every word has a predetermined position. The vocabulary does not reshuffle between sessions.

Real sensor input

Word selection begins with live readings from the iPhone's built-in magnetometer.

No microphone

Meridian Loom does not listen to, record or analyze speech.

Silence is valid output

Stable conditions do not trigger artificial responses simply to keep a session active.

The field becomes language.

The magnetometer's horizontal reading selects a vocabulary category; the vertical reading selects a word within it. Return to the same position and you return to the same word. The field may change. The mapping does not.

That's the whole mechanism — no hidden steps, no random fallback. The full breakdown, including what sensitivity and pacing actually change and why the app goes quiet, is on the How It Works page. For background on ITC methods and sensor mechanics more generally, see Field Notes.

Random selection creates activity. Fixed mapping creates a system.

Aspect Random-selection model Meridian Loom
Word source A word is selected from an available pool. The measured field position determines the word.
Mapping The relationship between sensor input and output may change with each selection. The vocabulary structure remains fixed between sessions.
Output behavior Regular output can maintain a sense of activity even when conditions are stable. Quiet periods are normal and expected.
Evaluation It can be difficult to determine why a particular word appeared. The mechanism is documented, and complete session transcripts can be reviewed and compared.

Capture the session, not just the moment.

Meridian Loom includes the tools needed to conduct, document and review an investigation from one iPhone.

Live word display

Each surfaced word appears clearly and can be spoken aloud, allowing you to continue observing the location rather than watching the screen continuously.

Complete session history

Review the full sequence of words from a session, along with individual timestamps.

Location and context

Record where a session took place and preserve the surrounding context for later review.

PDF export

Export a complete session transcript for your records, comparison or collaboration with other investigators.

Adjustable sensitivity

Tune how much field movement is required before Meridian Loom responds without changing the underlying word map.

Adjustable trigger pacing

Control the minimum pacing between surfaced words while preserving the relationship between each field position and its assigned word.

Motion damping

Smooths out readings during sessions where you're moving through a space, so repositioning isn't mistaken for field activity.

Private by design

Sensor readings and session records are processed and stored on your device. Meridian Loom does not collect your investigation data.

Better controls produce better questions.

Meridian Loom can be opened and used immediately, but reducing interference, establishing a baseline, and reviewing the full transcript afterward makes a session easier to interpret — and easier to compare against past sessions or another investigator's results.

Paranormal software should be honest about what it does.

Meridian Loom was created as an alternative to paranormal apps that simulate constant activity while obscuring how their output is produced. It gives you a transparent instrument, a documented methodology, and a complete record of what occurred. What the results mean remains yours to investigate.

More on why it was built →

Is Meridian Loom a random word generator?

No. Meridian Loom uses the iPhone's magnetometer reading to navigate a fixed vocabulary map. The same field position always corresponds to the same word.

Is Meridian Loom a real ghost-hunting app?

Meridian Loom is a functional sensor-driven instrument designed for paranormal investigation. It cannot determine whether a magnetic-field change has a paranormal cause, and it does not claim to prove spirit communication.

Does Meridian Loom listen through the microphone?

No. Meridian Loom does not access the microphone, listen for voices, record audio or use speech recognition to influence its output.

Why does Meridian Loom sometimes stay quiet?

Meridian Loom produces output only when the measured field crosses the configured response threshold. There's no filler or timer-based output to keep a session feeling active.
