Description
Show full descriptionShow less
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.
