EMF Detector - EMF Meter

Turn your phone into an EMF meter — Auto, Safety (ICNIRP) and Paranormal modes with µT readings, wire detection and full history. Free.

EMF Detector turns your iPhone's magnetometer into a precise electromagnetic field scanner with three purpose-built modes — and now keeps a full history of every reading you take.

THREE MODES • Auto — radial gauge with EMF level descriptions. • Safety — wire detection (background / weak / moderate / live wire) with ICNIRP public exposure zones (safe / caution / danger) and household appliance references. • Paranormal — baseline-relative anomaly detection. After 5s of baseline measurement, alerts you with 5-level intensity when EMF spikes deviate from normal — classic ghost-hunting workflow.

WHAT'S NEW • Measurement History — every reading is auto-saved with a 7-day trend chart and insights like "+12% vs your 7-day average". • Notes & Favorites — add a note ("bedroom wall outlet") and star to any saved reading. • Compare Mode — pick two saved readings and view the difference side by side. • Calibration Offset — fine-tune your sensor in ±1 µT steps. • Share Result — share your current EMF reading as an image. • CSV Export — share all your measurements as CSV for spreadsheets.

REFERENCE LIBRARY • ICNIRP public exposure limit (100 µT) • Household appliances: monitor, laptop, electric blanket, fridge, vacuum, induction cooktop, hair dryer • Wiring: background, weak field, wire detected, live wire • Paranormal classes 1–5

CORE FEATURES • Magnetometer-based magnetic field measurement (µT) • Real-time min/max/avg tracking • Radial gauge + chart visualization • Microphone-free, sensor-only

HONEST TECH NOTE iPhone magnetometers measure static and low-frequency magnetic fields. They cannot detect microwave / Wi-Fi / 5G RF radiation. The app reports what the sensor actually sees.
