Answers about the mechanism, the app, and how it's built.

No. Meridian Loom uses the iPhone's magnetometer reading to navigate a fixed vocabulary map. The horizontal field position selects a category, and the vertical position selects a word within that category. The same field position always corresponds to the same word.

The magnetometer — the same sensor behind the Compass app. It measures the strength and direction of the magnetic field around the phone.

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

No. Sensitivity changes how much magnetometer movement is required before the app responds. It does not change which word belongs to a given field position.

The magnetometer measures the field relative to the phone itself, not relative to the room. Rotating the phone changes the raw values it reports even if nothing around you has changed. See How It Works for more detail.

Meridian Loom only produces output when the measured field crosses the response threshold. If the field stays stable, nothing is spoken and nothing is logged — there's no filler or timer-based output to keep a session feeling active.

Give the environment and your phone a moment to settle before asking questions, and try to reduce nearby magnetic interference where you can. The Field Use guide covers this in detail.

There's no fixed length. Sessions with long silences and sessions with frequent output are both normal — length depends on what the field is doing, not a target the app is trying to hit.

Speakers, chargers, motors, magnetic phone cases or mounts, and other nearby electronics can all show up in the reading. Moving away from these sources reduces incidental noise.

Test mode is a way to see how Meridian Loom responds without needing real field movement — useful for getting familiar with the app before running an actual session. It's not intended for investigation use, and output generated while it's active isn't representative of normal field-driven behavior.

Session transcripts can be exported as a PDF from the session history screen for your own records or to share with another investigator.

Yes. Meridian Loom doesn't interpret or connect to other equipment, but many investigators run it alongside other tools and compare results afterward.

675 words across all 20 categories, along with the full set of session and investigation features — live word output, spoken output, transcripts, and adjustable sensitivity and pacing.

An additional 1,000+ words, bringing the full vocabulary to over 1,600 words across the same 20 categories. It's a single purchase, not a subscription.

Use the restore purchase option in the app's settings, signed in with the same Apple ID used for the original purchase.

No. Session data is processed and stored locally on your device. Meridian Loom does not collect your investigation data.

Only if you enable location for session logging. It's used to record where a session took place and isn't accessed otherwise.

Instrumental transcommunication — the practice of using electronic devices in attempts to communicate with spirits or other unexplained intelligences. Different ITC methods use radio frequencies, recorded audio, environmental sensors, or vocabulary-based instruments. Meridian Loom uses magnetic-field readings to navigate a fixed vocabulary.

A spirit box scans radio frequencies and relies on fragments of speech or noise picked up across stations. Meridian Loom doesn't use audio input at all — it maps a physical sensor reading to a fixed, predetermined vocabulary.

Both use the broader concept of environmental readings navigating a vocabulary, rather than simply selecting random words. Meridian Loom runs on an iPhone and uses its magnetometer specifically. Its vocabulary map is fixed, and the mechanism is documented openly. Meridian Loom is independently developed and isn't affiliated with the makers of the Ovilus.

No. It provides a consistent, documented structure that could theoretically be learned and navigated with intention if something were capable of influencing the magnetic field. It cannot prove that this occurs, or identify the cause of any given reading.
