Metal Map: Wall Scanner

Metal Map helps you scan, mark, and map magnetic anomalies around walls, floors, and objects using your iPhone’s built-in magnetic field sensor. Designed for renovation planning, DIY projects, and quick inspection tasks, Metal Map combines a real-time magnetic signal graph, AR heat spots, room mapping, and PDF export into one clean scanning workflow. HOW IT WORKS Metal Map does not “see” metal directly. Instead, it reads changes in the surrounding magnetic field using the iPhone magnetometer. Ferromagnetic metals such as iron and steel can create measurable magnetic anomalies, which may appear as signal peaks while scanning. The app first asks you to calibrate the local magnetic background. Then it filters sensor noise, tracks signal changes, and displays the result as a live radar-style graph. MAIN FEATURES REAL-TIME MAGNETIC SCANNER View magnetic field changes as a live signal graph. When the field changes, the scanner reacts with color, sound, and haptic feedback. AR HEATMAP POINTS Use the camera to place visual heat spots on walls or surfaces while scanning. Save detected points directly into your room scan. ROOM MAP Mark room corners, save scan points, and view a simplified top-down room map with detected magnetic locations. PDF EXPORT Export your room map as a clean PDF report for future renovation work, drilling planning, or documentation. CALIBRATION FLOW Calibrate the local magnetic background before scanning to reduce false signals and improve consistency. HAPTIC AND AUDIO FEEDBACK Use vibration and radar-like sound feedback to scan without constantly looking at the screen. METAL AND WIRE FOCUS MODES Switch between general magnetic anomaly scanning and wire-focused scanning behavior. Powered electrical lines may appear as pulsing magnetic signals depending on current load, distance, and wall material. IMPORTANT LIMITATIONS Metal Map mainly detects ferromagnetic metals such as iron and steel. Copper, aluminum, plastic pipes, and unpowered wires may not be visible to the magnetometer. Possible electrical source detection is only an estimate based on magnetic field behavior. Metal Map is not a certified electrical tester, stud finder, safety device, or professional inspection instrument. Always use proper certified tools before drilling, cutting, or performing electrical work.
