Metal Detector X50 – Real Metal Detection Using Your iPhone Detect metal using just your iPhone! Metal Detector X50 turns your device into a real metal detector by analyzing magnetic field changes using the built-in sensor. Modern iPhones include a magnetometer (part of the compass hardware) that can detect magnetic field variations caused by nearby metal objects. This app reads that data and displays a percentage-based detection level, with visual and sound feedback. How It Works: Uses your iPhone’s built-in magnetometer to detect magnetic metals. Displays detection as a percentage that increases near metal. Visual feedback with an animated circular indicator. Sound and vibration alerts for real-time detection. Adjustable sensitivity for more precise results. Tips for Best Results: Best sensitivity is near the camera area of your iOS device. Shake your phone to recalibrate the sensor if needed. Important: Not all iOS devices include a magnetic sensor. If your device does not support it, the app will not function properly. Please Note: This app cannot detect non-magnetic metals like gold, silver, or coins made of copper, as they are non-ferrous and do not produce a magnetic field. However… you might still discover a metal box with treasure inside! Features: Percentage-based detection level Adjustable sensitivity slider Real-time sound and vibration alerts Simple, intuitive interface No external hardware required Perfect for quick scans, fun exploration, or learning how your phone’s sensors work!
