Metal Detector with sound

"Metal Detector with sound" is an innovative app that transforms your smartphone into a metal detector. It utilizes the built-in magnetic sensor to measure electromagnetic field levels, alerting you with sound notifications when metal is detected. With features like calibration, min/max field level tracking, and a chart view of magnetic fluctuations, this app is perfect for detecting metal objects, electrical wires, or simply for fun. Note that it effectively detects ferromagnetic metals but not non-ferrous ones like gold or silver.
