Real iPhone magnetometer — genuine field readings, never faked numbers
617SW Apps
SpiritTrace: Ghost Detector EMF a real EMF meter, with a paranormal tint.
SpiritTrace is an iPhone entertainment app that reads your phone's real magnetometer and drives four instrument-style displays — Analog, Digital, 5-Bar, and Dual — so you can sweep a room for changes in the magnetic field. Raw readings, no random numbers, no fake ghosts.
Local-first
Built around a real sensor
Four meter faces — Analog, Digital, 5-Bar, and Dual — driven by the same live reading
Live µT readings presented in clear instrument-style displays
One-tap calibration that zeroes to the room so the needle reads real change
Geiger-style clicks and haptics that ramp up as the field climbs
Adjustable sensitivity for different rooms and investigations
For entertainment
SpiritTrace reads a real magnetometer. Interpreting readings as ghosts, spirits, or paranormal activity is for entertainment and atmosphere. It is not a safety or professional measurement instrument: it does not measure radiation, and it cannot detect Wi-Fi, Bluetooth, cellular or 5G signals, or microwave leakage.
