Magnetometer

Magnetometer is a precise magnetic field meter and metal detector that turns your phone into a real-time sensor toolkit. Measure field strength, find ferrous objects, and check compass interference with a clean, lightweight, offline app built for students, makers, and professionals. Core features include real-time magnetic field readout in microtesla or gauss with a live graph, a metal detector mode with adjustable sensitivity and vibration or tone alerts, and a built-in compass with calibration guidance to reduce drift. Optional data logging and CSV export help with experiments and field reports. Fast startup, low power use, and no account required.
