GhostScope
Read full descriptionHide full description
GhostScope is a ghost-hunting kit for fun. It cannot detect ghosts: it shows what your phone's sensors pick up and adds playful tools. EMF METER: shows your phone's real magnetometer reading in Β΅T or mG, with a 5-LED bar, peak and live graph. Magnets and speakers move it. Not a scientific instrument. EVP RECORDER: record with the microphone and play back slowed down. Free: 1 recording a day, plus 1 per rewarded ad. SPIRIT RADAR: a radar animation for atmosphere. Blips are random, a visual effect only. SPIRIT BOX: a radio-sweep game. Words are picked at random from a built-in list; a word drops sooner when your EMF reading jumps. Word history included. Entertainment only: nothing is being detected. SENSORS: live pressure, vibration and sound level from the sensors in your phone. PENDULUM: type a yes/no question; the answer comes from how you tilt the phone. HUNT LOG: saves your EMF sessions (duration, peak, events), the last 100. Free with ads. No ads while a hunt is running. GhostScope Pro (subscription or one-time purchase) adds unlimited EVP recordings, m4a export and sensitivity boost above x1.4, and removes ads. No account. Readings and recordings stay on your device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/
Meridian Loom

Meridian Loom is a field instrument for paranormal investigation, not a toy. It maps your iPhone's magnetometer reading to a fixed vocabulary β 1,695 words across 20 categories. Every position in the magnetic field corresponds to exactly one word. The mapping never changes. The premise is simple: if the system is truly fixed, something capable of influencing the magnetic field could learn it β the same way a person learns a layout β and use it to select words with intention. Not randomness pretending to be a presence. An actual fixed structure that a presence could navigate. That's why there's no random generator, no filler, no noise. When nothing is influencing the field, nothing is said. Silence is not a bug β it's what makes the words that do surface mean something. What it does: β’ Maps real-time magnetometer readings to a 1,695-word, 20-category vocabulary β’ Speaks each surfaced word aloud β’ Adjustable sensitivity and trigger pacing β tunes responsiveness, never the word mapping β’ Logs every session with timestamp, GPS, and full transcript β’ Exports session logs as PDF β’ Says nothing when there's nothing to read What it doesn't do: β’ Listen through your microphone β’ Generate random words for atmosphere β’ Let you choose themes or filter content β’ Promise contact β only a consistent structure that could be learned Meridian Loom is built for the ghost hunting and paranormal research community β people who've grown skeptical of apps that simulate activity instead of measuring anything. It's closer in spirit to instruments like the Ovilus than to ghost-hunting games: sensor-driven, deterministic, and transparent about exactly how it works. The free tier includes 675 words across all 20 categories. A one-time purchase unlocks the full 1,695-word vocabulary. This is an instrument for serious field use β a structure simple enough to be learned, by you or by something else.

Verdict
The clearest difference is ads: Meridian Loom at none against GhostScope's shown. Meridian Loom also leads on iOS requirement (15.1 vs 17.4). On price, in-app purchases and device support there is nothing between them.
