## Description

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.<br><br>Key features:<br><br>- Live magnetic field strength (µT) and 3‑axis values (X/Y/Z)<br>- Compass heading with tilt compensation<br>- Proximity indicator (COLD / WARM / HOT)<br>- Adjustable sensitivity (detection threshold)<br>- Sound and vibration alerts that intensify with stronger signals<br>- Calibration to set a baseline for accurate detection<br>- History graph to visualize changes over time<br>- Demo mode for testing on devices without a magnetometer<br><br>Notes:<br><br>- This app is for fun/experiments and does not replace professional metal detectors.<br>- Only magnetic (ferromagnetic) materials significantly affect the readings.
