GhostScope

Features
Read 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/

About

Meridian Loom

Read full description

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.
