EMF Meter & Metal Detector

See nearby magnetic-field changes with a calibrated baseline, live signal graph, peak reading, three sensitivity levels, sound, haptics, and honest guidance.

Turn your iPhone into a clear, guided magnetic-field meter.

EMF Meter & Metal Detector uses the iPhone magnetometer to show changes in the local magnetic field. It works best with magnets and nearby iron or steel. A guided calibration creates a local baseline, then the live meter shows change, total field, signal confidence, and recent peak.

MEASURE WITH CONTEXT • Guided setup for a dependable first reading • Calibrated change-from-baseline measurement • Live readings in microtesla (µT) or gauss (G) • Low, Balanced, and High sensitivity • 10-second signal history and peak reading • Optional sound and progressive haptics • One-tap recalibration • Offline measurement with no ads • VoiceOver, Dynamic Type, Reduce Motion, and increased-contrast support

HONEST BY DESIGN In this app, “EMF meter” refers only to the magnetic-field component available through the iPhone magnetometer. It does not measure electric fields, RF, Wi-Fi, 5G, or ionizing radiation.

The app cannot identify a material, estimate distance or depth, or confirm that an area is safe. Gold, silver, copper, aluminum, and other non-ferromagnetic materials may produce little or no response.

Readings vary with the iPhone model, case, object, distance, orientation, and surrounding electronics. Remove magnetic accessories when practical and compare the same iPhone edge and orientation.

Measurements stay on your device. No account is required.
