EMF Detector : EMF Meter

Turn your Android phone into a powerful EMF detector and radiation detector. EMF Detector : EMF Meter uses your device's built-in magnetic sensor (magnetometer) to measure electromagnetic fields around you in real time — no extra hardware required.

Whether you want to check EMF exposure at home, scan for hidden devices, locate metal objects, or explore unexplained magnetic field readings, this EMF meter app gives you fast, easy-to-read results on an analog needle meter, a digital LED display, and a live graph.

WHAT THIS EMF METER APP CAN DO
★ Real-time EMF & magnetic field readings in microTesla (µT) and Gauss (G)
★ Switch between analog meter, LED display, and live graph view
★ Adjustable measurement range and unit settings
★ Auxiliary field (H) calculation from your phone's magnetic sensor
★ Metal detector mode to help locate metal objects and cables
★ Scan for possible hidden devices, hidden cameras, and microphones
★ Simple, beginner-friendly interface with on-screen instructions
★ Lightweight app that won't slow down your phone

WHY USE AN EMF DETECTOR
Electromagnetic fields are produced by household wiring, appliances, routers, and other electronic devices. An EMF meter lets you observe the relative magnetic field strength in different areas of your home or workplace using your phone's existing magnetic sensor, so you can get a general sense of where EMF levels change. Many users also use an EMF detector app out of curiosity — moving the phone around a room or "suspected area" to watch how the readings shift, a popular way to explore unexplained EMF spikes.

HOW THE EMF DETECTOR APP WORKS
This EMF detector and radiation detector reads data directly from your Android device's magnetometer (compass sensor) and displays it as a live EMF reading. Because it relies on your phone's built-in sensor, accuracy depends on your device's hardware — a magnetic sensor is required for the app to function. Move your phone slowly near an outlet, appliance, or object to see the EMF meter respond.

KEY USE CASES
- EMF exposure checks at home or in the office
- Metal detector for finding metal objects, studs, and cables
- Hidden device and hidden camera scanning in unfamiliar rooms
- Exploring and recording unusual magnetic field activity
- Studying magnetism, electromagnetism, and the earth's geomagnetic field

Please note: EMF Detector : EMF Meter uses your phone's magnetic sensor and is intended for general awareness, educational use, and entertainment. It is not a certified scientific or medical-grade instrument, and results should not be used as a substitute for a professional EMF meter when precise measurement is required. Accuracy will vary by device.
