## Description

EMF Finder turns your Android phone into a portable electromagnetic field detector using the built-in magnetometer. It provides real-time µT readings with analog and digital meters, live graph view, adjustable sensitivity, sound alerts for spikes, and manual calibration. The app is optimized for low battery use and works offline, making it ideal for quick surveys, home checks, and educational demos.

Designed for hobbyists, students, engineers, and homeowners, EMF Finder helps locate hidden EMF sources, trace wiring behind walls, and monitor environmental magnetic fields. Note: the app requires a device with a magnetometer and is intended for general detection and educational purposes—not as a professional scientific instrument. Results depend on your phone’s sensor quality.
