Metal Detector - Metal Scanner

Fast, reliable metal detector app and EMF meter powered by your phone’s magnetometer. Turn your device into a precise metal scanner and gauss meter with clear, real‑time magnetic field readings for quick, confident checks. What this app does - Uses the built‑in magnetic sensor (magnetometer) to act as a magnetic field detector. - Displays the field strength instantly so you can spot ferromagnetic items (iron, steel) nearby. - Shows values like an EMF reader in engineering units for clarity and comparison. Who it’s for - DIYers and renovators who need help as a stud finder or nail finder when locating metal fasteners behind drywall. - Makers and hobbyists looking for a simple metal finder to test tools, screws, and small parts. - Students and curious minds who want a hands‑on EMF detector and gauss meter to learn about magnetism. - People who occasionally need a lightweight pipe detector or wire finder for steel pipes, rebar, or magnetic interference hotspots. Clear, real‑time reading - Live numeric reading behaves like an EMF meter and EMF reader for everyday checks. - Visual signal bar helps you notice changes at a glance when the field increases near metal. - Uses microtesla (µT) / milligauss (mG) so your measurements are meaningful and easy to compare. Practical uses and tips - Stud finder help: Move slowly across the wall to locate nails or screws securing studs. Look for a consistent peak across a vertical line. - Nail finder: Sweep at close range; the reading rises when the phone approaches nails, tacks, or small steel parts. - Pipe detector: Check floors or walls for iron or steel pipes; rebar and some fittings can produce a noticeable response. - Wire finder: Some power cables and transformers can influence the reading due to magnetic fields. Treat findings as guidance only. - Tool check: Verify magnetized tools or magnetic closures. A stronger magnet will raise µT/mG values even without visible metal. Accuracy matters - Works best on phones that include a magnetic sensor. If readings seem fixed or zero, your device may not have a magnetometer. - Nearby electronics, speakers, and strong magnets can affect the field. For a clean baseline, step away from large appliances. - Remove magnetic cases, clasps, or mounts before scanning; they can bias the sensor and make results less reliable. How to scan effectively 1) Open the app and note the baseline magnetic field reading (Earth’s field typically sits around a few dozen µT). 2) Move the phone slowly toward the area of interest. Watch for a steady increase on the bar and value. 3) If readings feel erratic, rotate the phone or make a figure‑8 motion to help your sensor calibrate. 4) Compare multiple passes. A repeatable peak near the same spot often indicates ferromagnetic metal. Responsible limitations - Not all metals are magnetic. Non‑ferrous materials like aluminum, copper, gold, and silver generally won’t trigger the sensor. - This app cannot make objects visible inside walls; it only reacts to magnetic fields and nearby ferromagnetic items. - Use the results as a guide. For safety‑critical work, confirm with professional tools. Feature highlights - Metal detector app with instant response from your phone’s magnetic sensor. - Magnetic field detector with values in microtesla (µT) / milligauss (mG). - Designed for quick checks as a metal scanner, metal finder, and steel detector. - Handy for DIY as a stud finder or nail finder when you look for metal fasteners. - Can assist as a basic pipe detector or wire finder in suitable cases. - Clear, readable UI focused on fast, reliable results. FAQ Q: Do I need special hardware? A: Your phone must include a magnetometer (magnetic sensor). Most mid‑to‑high‑end devices have one; some budget models do not. Q: Why do values jump near my TV or laptop? A: Electronics, speakers, and magnets disturb the local field. Step a bit farther away to re‑establish a stable baseline. Q: Can it find every kind of metal?
