## Description

Turn your device into a professional-grade magnetic sensor toolkit. This app uses a real-time 3-axis magnetometer to function as an EMF detector, Gauss meter, and offline compass. It’s designed for teachers, students, DIY enthusiasts, and outdoor explorers, delivering clear data and practical logging without gimmicks.

Key features include precise **3-axis readings in microtesla (µT)**, a custom **alerts system** with thresholds, a professional **data logger**, live **sensor analysis**, and **device sensor diagnostics**. It relies on your device’s magnetometer and may be affected by case size, nearby magnets, or interference, but provides a dependable offline tool for education, science projects, and field use.
