Metal Detector+: EMF Scanner

Metal Detector+ turns your iPhone into a powerful metal detection tool using the built-in magnetometer. Detect hidden metals, pipes, wires, and studs behind walls by scanning magnetic field disturbances. Scan any surface and watch the real-time radar animation react to nearby metal objects. The stronger the magnetic field change, the louder the audio feedback — just like a real metal detector. Key Features: - Real-time magnetic field scanning - Radar sweep animation with proximity indicator - Adjustable sensitivity for different environments - Auto-calibration for accurate readings - Audio beep feedback (faster = closer) - Signal strength graph over time - Metal type estimation (ferrous/non-ferrous) Perfect for DIY projects, home renovation, treasure hunting, or finding lost metal objects. No additional hardware needed — your iPhone's magnetometer does all the work.
