EMF - Detector (Magnetometer)

EMF - Detector turns your phone's built-in magnetometer into a clean magnetic field detector for everyday checks. Use it as an EMF meter, metal detector, and hidden device finder with live readings, a clear analog gauge, signal graph, and reading history.

Measure magnetic field strength in microtesla (uT) or milligauss (mG), watch changes in real time, and save readings when you want to compare results later. EMF - Detector is private by design: no account, no analytics, and readings stay on your device unless you choose to export them.

Key features:
- EMF meter for live magnetic field readings
- Metal detector mode for nearby metallic objects
- Hidden device finder mode for magnetic field spikes near electronics
- Analog gauge, digital readout, and live signal graph
- MIN, AVG, and MAX session stats while monitoring
- Save reading history with timestamps and signal level
- Switch between uT and mG units
- Adjustable alert and critical thresholds
- Sound and haptic alerts for high readings
- Light mode, dark mode, or system theme
- On-device privacy with no account required

EMF - Detector uses the magnetic field sensor available on many Android phones and tablets. Results depend on your device hardware and nearby magnetic interference.
