About this app

Magnetometer is the most accurate EMF detector, metal detector, and magnetic field meter for Android. Read live electromagnetic field strength in microtesla (μT) or milligauss (mG) in seconds.

Whether you hunt for hidden wires, find studs in walls, scan for ghosts (paranormal mode), or check Wi-Fi router EMF — Magnetometer turns your phone into a precision EMF/metal scanner.

▶ MAIN FEATURES
• Magnetometer — live magnetic field reading (μT and mG)
• EMF detector — electromagnetic field scanner with audio alert
• Metal detector — magnetic anomaly detection
• Stud finder mode — find metal beams behind drywall
• Compass mode — true north heading
• EMF chart history — last 60 seconds of readings
• Calibration mode — figure-8 motion tutorial
• Audio + vibration feedback above threshold
• Dark mode for paranormal investigations
• Works fully offline — no account, no ads block

▶ HOW TO USE
1. Open Magnetometer and move your phone in figure-8 motion to calibrate
2. Move the phone near walls, wires, or metal objects
3. Watch the gauge rise as field strength increases
4. Set audio alert threshold for hands-free scanning

▶ WHO USES MAGNETOMETER
• Electricians finding hidden wiring behind walls
• Carpenters and DIY hobbyists locating studs and metal beams
• Paranormal investigators using EMF detector during ghost hunts
• Tech-conscious users measuring Wi-Fi router and microwave EMF
• Treasure hunters scanning for buried metal coins
• Anti-spy enthusiasts checking for hidden surveillance devices
• Hikers using compass when GPS fails
• Mechanics finding magnets in machinery
• Educators teaching about magnetism and electromagnetic field
• Hardware tinkerers debugging magnetic interference

Replace bulky EMF meters and analog metal detectors with a tool you already carry. Magnetometer is fast, accurate, and free.
