About

This app uses your device's sensors to detect and visualize magnetic and electromagnetic fields. Explore magnetic forces, identify potential sources of EMF, or use it as a simple metal detector. See real-time fluctuations plotted on a responsive display.

✓Detects magnetic fields on x, y, and z axes
✓Visualizes EMF activity in real-time
✓Indicates computed field magnitude
✓Functions as a basic metal detector
✓Plots EMF activity as a sin wave

What's New in EMF Detector

2.0

October 17, 2026

EMF Detector has been rebuilt for today's iPhone and iPad. • A new industrial instrument panel with an animated analog dial and luminous digital display. • Calibrated magnetic readings, signed X/Y/Z components, and total field strength. • A rolling trace, session peaks, HOLD, RESET, and three dial ranges. • An electrical hum that follows the field, substantial mechanical button sounds, and tactile feedback on supported iPhones. • A remembered mute setting for all instrument audio. • Portrait and landscape layouts, a field guide, and labeled demonstration mode. • An offline privacy policy. Readings stay on your device. This update requires iOS or iPadOS 26 or later.

It is a great app but says the creator has not updated it yet and now it doesn’t work. Bummer. Plz update your app, app dudes! Ty!

Off Scale By Induction Cooktop

On my iPhone 5 the 3 sensors are extremely directional. Checking my kitchen for HOT SPOTS, I discovered a TOTALLY OFF SCALE spot at the upper left front corner of my Kenmore Induction Cooktop even with unit off and safety ON. Strangely this Needle Pegged HOT SPOT is at the Kenmore Logo? I wish I knew why?
