Smart Metal Detector & Scanner

Detect magnetic metal, scan surfaces for magnetic fasteners, compare objects, and measure magnetic-field changes in real time using your iPhone. Smart Metal Detector & Scanner uses the iPhone’s built-in magnetometer to measure magnetic-field strength in microtesla (µT). Explore walls, surfaces, objects, appliances, and electronics with live readings, calibrated comparisons, results and Surface Sweep Pro. REAL-TIME METAL DETECTOR Monitor magnetic-field activity as it happens. • Live magnetic magnitude • Current deviation • Peak reading • Signal status Move your iPhone slowly around an object or area and watch for repeatable magnetic-field changes. STUD FINDER & WALL SCANNING Scan walls and surfaces for magnetic variations caused by nearby nails, screws, metal fasteners, and other ferromagnetic materials. The app measures magnetic-field changes and does not directly detect wood studs or see through walls. MULTIPLE SCAN MODES Metal Scanner Measure nearby magnetic activity with live readings and detection feedback. Surface Sweep Pro Scan walls, appliances, and flat surfaces row by row to create a structured magnetic-variation map. Object Scanner Calibrate the environment, then compare an object against the baseline. Electronics Scan Inspect magnetic-field variation around electronics, chargers, speakers, motors, and appliances. SURFACE SWEEP PRO Create grid-based magnetic-variation maps using quick, standard, or detailed scan densities. Track: • Completed scan cells • Surface coverage • Signal quality • Valid and rejected samples • Average field values • Maximum deviation • Peak readings • Anomaly levels CALIBRATION & COMPARISON Establish an environmental baseline before comparison scans to understand how later readings differ from surrounding magnetic activity. DETAILED SCAN RESULTS Review useful measurements after every scan: • 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 supported scans and Surface Sweep sessions for later review. Revisit previous measurements, signal-quality summaries, mapped surfaces, and detailed results. MAGNETOMETER MEASUREMENTS Use your iPhone’s magnetic sensor to explore magnetic-field strength around: • Magnetic objects • Metal fasteners • Nails and screws • Electronics • Speakers • Motors • Chargers • Appliances Measurements are displayed in microtesla (µT). GUIDES & EDUCATION Learn how magnetic detection works and what your iPhone magnetometer actually measures. Explore: • Magnetic response types • Metal and object behavior • Scanning techniques • Calibration practices • Signal interference • Troubleshooting • FAQs PREMIUM Upgrade to Premium to unlock Surface Sweep Pro, premium scanning functionality, and an ad-free experience.

IMPORTANT SENSOR INFORMATION Smart Metal Detector & Scanner measures magnetic-field strength using the iPhone magnetometer. Readings can be influenced by ferromagnetic materials, permanent magnets, speakers, motors, chargers, electronics, object size, distance, phone orientation, and environmental interference. Magnetic response does not identify exact material or composition. The app cannot see through walls or floors and is not a replacement for professional inspection, diagnostic, electrical, safety, security, or medical equipment. Explore magnetic-field activity around you with Smart Metal Detector & Scanner.
