Spirit Box: Ghost EMF Detector

Four ghost-hunting instruments in your pocket. Spirit Box turns your iPhone's own sensors into an EMF meter, a spirit box, an EVP recorder, and a live sensor dashboard — wrapped in a premium, hand-built instrument panel.

The lights flicker. The needle twitches. Somewhere in the noise, a word forms. Are you listening?

EMF METER
A real electromagnetic-field meter driven by your device's magnetometer. Watch the analog needle climb and the LED bar light as the field shifts, with adjustable sensitivity and peak-hold.

SPIRIT BOX
Open a session and the box scans, pulling words from a large dictionary in real time — spoken aloud and printed on screen. The static thins and the panel stirs as the magnetic field rises around you, so you hear the room in the signal. Pro unlocks a much bigger word bank and lets you add your own.

EVP RECORDER
Capture short audio sessions, watch the live waveform, and replay them to listen for anomalies. Your recordings stay on your device.

SENSOR DASHBOARD
Magnetic field, motion, and heading on live graphs — read every channel at once and catch the moment everything goes quiet.

SESSION LOG
Every spirit-box scan is logged with its words, duration, and peak EMF. Review the full timeline free. Pro replays a whole session — every word again, in its original order and timing — and exports a shareable report card.

INSTRUMENT SKINS
Change the look of the whole rig. Spectral Green ships free; Pro adds Amber CRT, Night Vision, and Cryo.

NO ADS, NO SUBSCRIPTION
Every instrument is free to use, with no daily limits and nothing to sit through. Pro is a single one-time unlock, not a rental.

PRIVACY
Everything runs on your device. No tracking, no data collected, and recordings never leave your phone.

FOR ENTERTAINMENT ONLY
Spirit Box reads real sensors and reacts to your environment, but it cannot detect or communicate with spirits. Words and sounds are generated by the app for entertainment and do not represent real communication. Don't rely on it for safety, health, or any important decision.
