Metal Detector: EMF Scanner

Turn your smartphone into a convenient Metal Detector & EMF Scanner using the built-in magnetometer sensor.
Metal Detector: EMF Scanner helps you observe changes in nearby magnetic fields and visualize sensor data in real time. Whether you're exploring magnetic objects, learning about electromagnetism, or experimenting with your device's sensors, this app provides an easy way to monitor magnetic activity.
Designed for educational and general-purpose use, the app measures magnetic field strength and displays live values through meters, graphs, and sound alerts.
🔍 Key Features
🧲 Metal Detection
Use your phone's magnetic sensor to monitor changes in nearby magnetic fields that may be caused by metallic objects with magnetic properties.
📡 EMF Scanner
Measure surrounding electromagnetic field (EMF) activity and observe live sensor readings directly on your device.
💛 Gold Signal Indicator
View magnetic field variations that may be associated with certain metallic objects.
This feature analyzes magnetic responses only and does not identify or verify precious metals.
📷 Camera Overlay
Watch magnetic field changes while viewing your surroundings through the camera overlay, making it easier to observe sensor activity in real time.
🔔 Sound Alerts
Receive automatic beep notifications when magnetic field intensity changes beyond your selected threshold.
📊 Live Meter & Graph
Monitor magnetic field strength with an easy-to-read digital meter and real-time graph.
🎚 Adjustable Sensitivity
Customize detection sensitivity for different environments and magnetic conditions.
📈 Real-Time Sensor Values
Track magnetic field measurements continuously as you move your device around nearby objects.
📘 How It Works
Metal Detector: EMF Scanner uses your phone's built-in magnetometer sensor to measure changes in the surrounding magnetic field.
When magnetic intensity changes, the app displays live values, visual indicators, graphs, and optional sound alerts.
Performance depends entirely on your device's hardware. Phones without a magnetometer sensor cannot support metal detection features.
