Features & Capabilities

Professional Geomagnetic Data Collection Tool

Magnetic Monitor is a professional app designed for earthquake research and geomagnetic data collection. Utilizing iPhone's built-in magnetometer, it enables high-precision real-time collection, analysis, and export of geomagnetic field data.

Core Features

Real-time Data Collection 1Hz sampling rate for precise magnetic field recording. Auto-calculate total field, horizontal component, declination, and inclination. Real-time display of X, Y, Z axis magnetic field data in nanoTesla units.

GPS Positioning Accurate recording of sampling point coordinates and altitude. Real-time positioning accuracy display. Background location updates support.

Data Visualization 4 synchronized real-time charts showing magnetic field changes. Step interpolation algorithm for clear discrete sampling data. Auto-scaling axes for different data ranges.

Data Management Local persistent storage, data never lost. Support for adding notes. Quick search through historical records.

Data Export (Premium Feature) JSON format: Complete data structure with metadata and statistics. CSV format: Excel compatible for easy analysis. Unlimited export of any number of sampling points.

Statistical Analysis Auto-calculate mean, standard deviation, max, and min values. Magnetic interference detection alerts. Collection duration and sample count statistics.

Use Cases

Earthquake precursor research Geomagnetic field monitoring Scientific data collection Educational demonstrations Magnetic environment assessment

Technical Features

MVVM architecture for clean code structure. CoreMotion framework ensuring data accuracy. Swift Charts library for smooth visualization. Support for 10 language interfaces.

Usage Tips

Recommend 3-5 minutes collection per sampling point. Stay away from metal objects and electronic devices. Keep device level and stable. Best results in outdoor open environments.

Privacy Protection
