Magnet Meter - Field Detector

Magnetometer & Metal Finder

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Turn your iPhone into a magnetic field detector. Find magnets, magnetized metal & field anomalies with a live gauge, compass & AR heatmap. Magnet Meter turns your iPhone's built-in magnetometer into a powerful magnetic field detector and metal finder. Sweep your phone over any surface and watch the live gauge, color heatmap, and audio tones react instantly as you close in on magnets, magnetized metal, and hidden magnetic anomalies. WHAT YOU CAN DO - Detector gauge: a big, easy-to-read radial meter shows magnetic field deviation in real time, with peak-hold so you never miss a spike. - Audio + haptic feedback: hear and feel the field get stronger, so you can scan without looking at the screen. - Axis view: see the raw X, Y, Z magnetic components and total field strength. - Waterfall: a scrolling history graph reveals how the field changes as you move. - Compass: a true-north compass that also shows how nearby metal bends the field. - AR Heatmap (Pro): paint magnetic field strength right into the space around you using your camera. WHAT IT FINDS Magnet Meter detects changes in the magnetic field. It is great for finding magnets, magnetized steel and iron, speaker magnets, hidden hardware, rebar, and magnetic studs. Because it measures magnetism, it does NOT detect copper pipes, aluminum, or live AC wiring. ZERO / CALIBRATE Tap Zero to capture the ambient field as your baseline, so only nearby objects register. A built-in calibration prompt helps keep readings on track. CUSTOMIZE - Multiple color maps and units (microtesla, gauss, milligauss) - Adjustable sensitivity - Clean, focused interface designed for one-handed sweeping MAGNET METER PRO A single one-time purchase (no subscription) unlocks the AR magnetic heatmap, CSV session export, a finer sensitivity floor, watermark-free sharing, and removes ads. Your purchase applies to your Apple ID across all your devices. IMPORTANT Magnet Meter is for educational and entertainment use only. Readings are relative and approximate and may be inaccurate. It is not a calibrated scientific or safety instrument: do not rely on it to locate live electrical wiring, gas lines, or any hazard. Requires a device with a magnetometer.
