Turn your iPhone into an EMF detector and gauss meter. EMF Detector reads the built-in magnetometer and shows live magnetic field in microtesla, milligauss, or Gauss — the same units a handheld meter uses. This app measures magnetic fields. It does not measure Wi‑Fi, 5G, or ionizing radiation. What you can do • Live EMF detector with peak hold and average • Switch units: µT, mG, Gauss • Zero / calibrate to ignore Earth’s field and hunt nearby sources • Ghost hunt mode: audio and haptics on magnetic spikes (used by investigators as a starting point, not a spirit detector) • Metal and stud finder: sweep a wall to find studs, pipes and wiring • XYZ charts and field direction compass • Session log with CSV and PDF export Ghost hunt & metal Walk slowly. Zero the meter, then sweep. Spikes mean a changing magnetic field — speakers, transformers, studs, or wiring. Audio maps spike strength so you can hunt without watching the screen. Pro removes ads and unlocks direction, full history, high-EMF alerts, and PDF export.
