Turn your smartphone into a powerful and advanced Metal Detector, Metal Identifier, and Metal Scanner using your device’s built-in magnetic sensor. Metal Detector transforms your phone into a real-time magnetic field detection tool powered by the magnetometer. It measures surrounding magnetic field strength and detects changes caused by hidden or nearby metal objects. In addition to detection, the app helps you identify metal presence through magnetic response patterns and scan areas to locate metallic objects more precisely. No complicated setup. No extra hardware. Just open the app and start scanning your environment in seconds. ADVANCED METAL DETECTION, IDENTIFICATION & SCANNING Metal Detector uses sensitive magnetometer readings to analyze magnetic field fluctuations in real time. When metal is nearby, values increase instantly, helping you detect, track, and scan the area with better precision. Move your phone slowly across surfaces and watch live sensor data react dynamically. The closer you get to metal, the stronger and more responsive the signal becomes, allowing you to pinpoint object locations. FEATURES (PRO REQUIRED) All premium features require Pro access for the best performance: Real-time metal detection with live sensor feedback Metal identifier based on magnetic response changes Area scanning mode for locating hidden metal High sensitivity scanning mode for precision results Live magnetic field strength meter (µT / microtesla) Detect hidden metal objects around you Unlimited scans with no restrictions Sound alerts when metal is detected nearby Vibration feedback for instant proximity awareness Fast, stable, battery-efficient performance Clean, minimal, and user-friendly interface Smooth visualization of magnetic field changes DETECT AND IDENTIFY METAL ANYWHERE Use Metal Detector to help find and identify: Lost keys, coins, jewelry, and small metal items Metal pipes hidden behind walls Electrical wiring locations under surfaces Metal structures and objects nearby Hidden metallic objects in different environments Instant visual, sound, and vibration feedback allows efficient scanning at home, office, garage, workshop, or outdoors. HOW IT WORKS The app uses your phone’s built-in magnetometer sensor to detect magnetic disruptions caused by metal objects. As you move your device, the app measures magnetic field strength and helps you scan and identify metal presence in real time. For best results: Move slowly and steadily while scanning Keep your phone close to the surface Avoid strong electronic interference Calibrate by rotating your device if readings seem unstable REAL-TIME SENSOR VISUALIZATION Watch magnetic field changes live on your screen with a responsive meter that reacts instantly. This visualization helps you understand how close you are to metal and improves your scanning accuracy.
