Observe changes in nearby magnetic fields and visualize sensor data in real time — with a live meter, graph, camera overlay and sound alerts. No extra hardware needed.
Powered entirely by your device's built-in magnetometer — visualized in a clean, easy-to-read interface.
Monitor changes in nearby magnetic fields that may be caused by metallic objects with magnetic properties.
Measure surrounding electromagnetic field activity and observe live sensor readings directly on your device.
View magnetic field variations that may be associated with certain metallic objects — magnetic response only.
Watch magnetic field changes while viewing your surroundings through the camera to observe activity in real time.
Get automatic beep notifications when magnetic field intensity changes beyond your selected threshold.
Monitor magnetic field strength with an easy-to-read digital meter and a real-time scrolling graph.
A clean, high-contrast interface built for reading sensor data at a glance.
Metal Detector: EMF Scanner uses your phone's built-in magnetometer to measure changes in the surrounding magnetic field. When intensity changes, the app shows 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.
This application measures magnetic field changes only. It is not a professional metal detector, cannot detect underground treasure or buried objects, and does not identify, verify or confirm gold, silver, gemstones or other precious metals. Detection accuracy depends on your phone's magnetometer sensor and surrounding magnetic conditions; results vary by device model and nearby interference. Intended for entertainment, education and basic magnetic field measurement only.
