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 reference zones based on ICNIRP public reference levels (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 reference level for 50/60 Hz (100 µT), shown for context • 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.

Verdict

The call

The clearest difference is rating: WaveBlock® EMF Meter at 5.0 against EMF Detector's 4.0. WaveBlock® EMF Meter also leads on ads (none vs shown) and monetization model (free vs ad-supported). EMF Detector's advantage is update cadence (every 4 days vs every 2 weeks) and ratings volume (7 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.
