Smart Metal Detector & Scanner

Turn your iPhone into a smart magnetic-field scanner with real-time readings, guided scan modes, object comparison, surface mapping, and saved results. Smart Metal Detector & Scanner uses the iPhone’s built-in magnetometer to measure nearby magnetic-field changes in microtesla (µT). Explore magnetic activity around objects, surfaces, appliances, electronics, and other areas while comparing live readings against the surrounding environment. REAL-TIME METAL SCANNER Monitor magnetic-field activity as it happens. • Live magnetic magnitude • Environmental baseline • Current deviation • Peak reading • Signal status • Scan duration Move your iPhone slowly around an area and watch for repeated magnetic-field changes. MULTIPLE SCAN MODES Metal Scanner Monitor nearby magnetic activity with live readings and detection feedback. Surface Sweep Pro Scan walls, appliances, flat objects, and other surfaces row by row to create a structured magnetic-variation map. Object Scanner Calibrate the surrounding environment, then compare an object against the established baseline. Electronics Scan Inspect magnetic-field variation around everyday electronic devices and appliances. SURFACE SWEEP PRO Create grid-based magnetic-variation maps using quick, standard, or detailed scan densities. Track completed cells, coverage, signal quality, rejected samples, average field values, deviation, and peak readings across the scanned surface. CALIBRATION & COMPARISON Establish an environmental baseline before comparison scans. Calibration helps you understand how later readings differ from the magnetic field around you. DETAILED SCAN RESULTS Review useful scan statistics, including: • Average magnetic magnitude • Minimum and maximum readings • Peak reading • Maximum deviation • Valid and rejected samples • Signal quality • Highest anomaly level • Result interpretation SCAN HISTORY Save live scans and Surface Sweep sessions for later review. Revisit previous measurements, signal-quality summaries, and scan results whenever you need them. GUIDES & EDUCATION Learn how magnetic detection works and what your iPhone magnetometer actually measures. Explore guides covering: • Magnetic response types • Metal categories and object behavior • Scanning techniques • Calibration practices • Troubleshooting and FAQs • Safety information • Common interference sources IMPORTANT SENSOR INFORMATION The iPhone magnetometer measures magnetic-field strength. Magnetic response can be influenced by ferromagnetic materials, permanent magnets, speakers, motors, chargers, electronics, object size, distance, orientation, and environmental interference. Magnetic response does not identify the exact material or composition of an object. The app cannot see through walls or floors and is not a replacement for professional inspection, diagnostic, safety, or security equipment.
