Real Metal Detector: Magnetic Field Scanner Turn your iPhone into a powerful metal detector. Real Metal Detector uses the built-in magnetometer sensor to detect ferromagnetic metals like iron, steel, nickel, and cobalt hidden in walls, floors, and everyday objects. REAL-TIME DETECTION Scan your surroundings and watch the signal respond instantly. The circular gauge, deviation readout, and X/Y/Z axis display give you precise magnetic field data in real time. Move your device slowly and watch the numbers change as you approach metal objects. PROFESSIONAL GAUGE A beautifully designed circular gauge with 60 precision tick marks shows field strength at a glance. The color-coded arc shifts from green through yellow and orange to red as signal intensity increases, with a rotating scanner line for visual feedback. PRO FEATURES Signal Graph — Three visualization modes (Deviation, Axes, Magnitude) with smooth area charts and live readings for X, Y, Z, magnitude, and deviation. Sensitivity Control — Fine-tune detection range from Low to Maximum. Exponential scaling lets you detect subtle changes or ignore background noise. Session Recording — Save scan sessions with timestamped readings. Review history with stats (min, avg, max) and mini charts. Advanced Haptics — Graduated vibration feedback that intensifies as you get closer to metal. Feel the detection, don't just see it. GUIDED CALIBRATION Four-step calibration establishes an accurate baseline: move away from metal, perform a figure-8 motion, hold still for a 3-second countdown, and you're ready. Skip anytime if you prefer quick scans. AUDIO FEEDBACK Geiger-counter style clicks that speed up as signal strength increases. Frequency ranges from slow ticks to rapid-fire clicks. Adjustable volume so you can scan with the screen off. BUNDLED TOOLS Stud Finder — Detect wall studs, pipes, and rebar using magnetometer deviation from baseline. One-tap calibration, visual deviation bar, and deep tick audio feedback. EMF Meter — Measure electromagnetic field strength in milligauss with color-coded risk levels (Safe, Low, Moderate, High). Reference table and real-time history graph. Spy Camera Detector — Scan dark rooms for hidden IR cameras using your device camera. Adjustable sensitivity slider highlights bright, low-saturation spots that may be infrared LEDs. Radar ping and alert sounds. Each tool includes its own real-time synthesized sound effects that can be toggled in Settings. WHAT IT DETECTS Ferromagnetic metals: iron, steel, nickel, cobalt, and alloys containing these metals. Find studs in walls, rebar in concrete, pipes behind plaster, lost screws, nails, keys, and other ferrous objects. LIMITATIONS This app uses the device magnetometer and cannot detect non-ferrous metals (gold, silver, copper, aluminum). Detection range is limited to a few centimeters. Accuracy varies by device model. Not a replacement for professional metal detectors. FREE TO USE, PRO UNLOCKS EVERYTHING The detector, gauge, audio feedback, and calibration are free. Pro unlocks signal graphs, sensitivity control, session recording, advanced haptics, and removes ads. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel in your Apple ID account settings.
