Magnetometer: Metal Detector

diamond-dave

About this app

Magnetometer is a real‑time magnetic field viewer for Android. It shows live µT readings, heading, and a history graph so you can see how the magnetic field changes as you move your device.

Key features:

- Live magnetic field strength (µT) and 3‑axis values (X/Y/Z)
- Compass heading with tilt compensation
- Proximity indicator (COLD / WARM / HOT)
- Adjustable sensitivity (detection threshold)
- Sound and vibration alerts that intensify with stronger signals
- Calibration to set a baseline for accurate detection
- History graph to visualize changes over time
- Demo mode for testing on devices without a magnetometer

Notes:

- This app is for fun/experiments and does not replace professional metal detectors.
- Only magnetic (ferromagnetic) materials significantly affect the readings.

What’s new

"What's new"

• All-new sonar-style field scanner with live sweep, detection pulses, and compass bezel
• Redesigned home screen: large µT readout, at-a-glance status, one-tap Calibrate
• New signal timeline showing change from your calibrated baseline, with threshold guides
• Fresh dark instrument theme, new app icon, and branded launch screen
• Clearer guidance: detects ferromagnetic metals (iron/steel) only — not gold or silver
• Performance and stability improvements
