Metal detector - Metal sniffer

"Metal detector - Metal sniffer" is an Android app that utilizes your device's built-in magnetic sensor to detect nearby iron metal objects by measuring electromagnetic fields. The app displays the current magnetic field value in μT (microtesla) and allows users to adjust sensor speed and set minimum detection thresholds. However, it's important to note that this app only detects iron; gold, silver, and copper coins are not detectable due to their lack of magnetic properties. Enjoy additional features like a laser light simulator for a fun experience!
