About

Metal Detector

Features
Read full description

Find hidden screws, nails and steel objects with your iPhone's built-in magnetometer. IronScope shows the live magnetic field in µT and beeps faster as you get closer. Works fully offline — no ads, no account. WHAT IT FINDS • Steel screws and nails behind drywall (a quick way to locate where a stud is fastened) • Iron and steel objects, magnets and magnetic mounts at close range • Changes in the magnetic field around electronics and accessories IronScope detects ferromagnetic metal only. It cannot see wood, plastic, aluminum or copper, and it does not locate wooden studs directly — it finds the metal fasteners in them. KEY FEATURES • Real-time magnetic field reading in µT with a color-coded gauge • Audio alert that speeds up near strong signals • Scan Confidence card: sensor, baseline, signal and next step at a glance • Works on iPhone and iPad models with a magnetometer • Calibrated magnetometer readings (the system-calibrated field, not the phone’s raw sensor bias) • Automatic baseline when you open the app, plus a figure-8 prompt if the sensor needs calibration IRONSCOPE PRO • Saved calibration to your local baseline • Signal Marks: save up to 7 readings and recheck the same spot later • Live signal history and 60 Hz high-precision sampling • CSV export of your readings HOW IT WORKS The magnetometer reads the ambient field, often 25–65 µT from the Earth alone. IronScope compares the live reading with a baseline and shows the excess as signal strength. Readings vary by phone model, orientation, cases, magnets and nearby electronics. LIMITATIONS A phone magnetometer is not a professional metal detector. Range is a few centimeters. Do not use IronScope for security screening, mining, locating buried pipes or cables, or any safety decision. PRIVACY Readings are processed on your device. No location, audio, analytics, ads or tracking.
