METAL DETECTOR PRO - 7 Modes, 1 iPhone Turn your iPhone into a professional-grade metal detector and magnetic field analyzer. MetalDetector Pro harnesses your device's built-in magnetometer to detect metal ferrous e magnet , measure electromagnetic fields, and visualize magnetic data in stunning real time — no extra hardware, no subscriptions, no limitations. ••• 7 POWERFUL MODES - SEARCH The classic metal detection experience, reimagined for modern iPhones. The app continuously reads the ambient magnetic field in microtesla (µT) and alerts you with audio beeps and haptic pulses as intensity changes. A 20-bar VU meter and three LED indicators give you instant, at-a-glance feedback. Perfect for locating hidden nails, coins, keys, electrical wiring, pipes and any ferromagnetic object beneath walls, floors or soil. • THRESHOLD Set a custom detection threshold and let the app work hands-free. Alerts fire only when the field exceeds your chosen sensitivity level — ideal when you need to focus on the surface you're scanning without watching the screen. • EMF Electromagnetic field meter mode. Identify live electrical wiring hidden inside walls, locate appliances radiating strong fields, and monitor your environment with a dedicated EMF intensity readout. A useful companion for electricians, home inspectors and the curious. • COMPASS A precision magnetic compass driven entirely by the magnetometer sensor — no GPS required. Clean neomorphic design with a smooth, real-time compass rose. Reliable heading data anywhere, even underground or indoors. • SPHERE The most visually striking mode in the app. Every sensor reading is plotted as a colored dot on a rotating 3D globe. Watch your scan history build into a living magnetic map — green for low-intensity fields, climbing through yellow and orange to alarm red as intensity rises. A mesmerizing way to understand the invisible forces around you. • DEPTH Estimate how deep a metallic source is hidden using real-time field gradient analysis. Point your iPhone at a wall, floor or patch of ground, press CALIBRATE, and receive a live distance readout in centimeters. Great for locating buried pipes, conduits and structural reinforcement. • 3D FIELD An immersive real-time particle simulation driven by the live magnetic field vector. Hundreds of animated particles drift, swirl and accelerate in response to the X, Y and Z field components. The stronger the field, the faster and more dramatic the particle storm becomes. ••• PREMIUM FEATURES ••• • Live µT readout with individual X, Y, Z axis values on a retro LCD display • 20-bar VU meter with green, yellow and red intensity zones • 3 LED indicators with progressive glow effect • Scrolling magnitude graph — last 150 samples always visible • Precision sensitivity slider with real-time signal filtering • Audible beep alerts with adjustable sensitivity • Haptic vibration feedback, independently togglable • Flashlight/torch for dark and confined environments • Auto-lock disable — screen stays on during extended scans • Neomorphic UI in both Light and Dark theme • Authentic retro LCD display with green phosphor aesthetics • Full localization: English and Italian ••• WORKS ON EVERY IPHONE No LiDAR. No external sensors. MetalDetector Pro runs on any iPhone with iOS 15 or later, using only the standard magnetometer chip built into every device. No camera permissions. No location tracking. Your data never leaves your device. ••• WHAT CAN YOU FIND? Buried metal ferrous e magnet-Nails and screws hidden in walls-Underground pipes and conduits-Live electrical cables · Lost keys and metal objects · Metal studs behind drywall · Old relics and artifacts Whether you're a DIY enthusiast, a treasure hunter, an electrician or simply curious about the invisible magnetic world around you — MetalDetector Pro delivers the most powerful, beautiful and complete magnetometer toolkit on the App Store.

Compass calibration screen appeared out of nowhere after 5 min use. No useful documentation. Author's website under construction. ### 5/5 — wow nice *2013-10-16* the best Metal Detector.... ### 4/5 — Beautifull *2013-10-16* beautifull graphics, work very well on my iPhone 4s, great work ### 5/5 — nice new graphics! *2013-10-16* work very well in my iPhone 5C ### 5/5 — good work *2013-10-16* nice, new version is good… enjoy ### 1/5 — Not worth a cent *2013-08-27* Wish I hadn't purchased this gizmo, absolute bummer. 0 stars (review didn't let me submit without tapping a star). ### 1/5 — Useless *2013-05-11* Not worth it ### 1/5 — Brooks Jolley *2013-03-06* I have iPhone 4 and I got this metal detector and a free one, I kid u not the free one works better. Oh we'll, you'll have that. I guess there's my two dollar donation to I phone gadgetry. Maybe they'll improve or maybe it's my outdated phone. :p It does detect magnets well however. ### 5/5 — Works fantastic :) *2013-01-07* I had old keys and they were metal Also had silver too it worked so everybody who needs their money back well It works great on iPhone 4S ok :) ### 1/5 — Money Back Please! *2012-05-14* Does not work on iPhone 4s ## Frequently asked questions about Metal Detector & Magnetometer ### What can Metal Detector Professional find?
