EMF Detector - EMF Meter

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.
