Magnetometer with live field readings, proximity alerts, and compass heading.
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.
