About this app

Turn your device into a professional-grade magnetic sensor toolkit.
Measure magnetic fields with precision and navigate confidently using your phone's built-in hardware. This app transforms your device into a reliable EMF meter, Gauss meter, and offline compass. Designed for teachers, students, DIY enthusiasts, and outdoor adventurers, it provides clear, real-time data without the gimmicks.
🚀 Key Features
• Precise EMF & Magnetic Field Meter: Monitor magnetic field strength in real-time using 3-axis (X/Y/Z) magnetometer data. View accurate readings in microtesla (µT) to detect magnetic interference or strength.
• Offline Compass for Navigation: Access a dependable compass that works without mobile data or Wi-Fi. Perfect for hiking, camping, and orienting yourself in remote locations.
• Custom Alerts & Thresholds: Set your own specific limits. Receive instant notifications when the magnetic field exceeds your chosen threshold.
• Professional Data Logger: Record your sensor readings over time. Review detailed logs directly within the app—ideal for science experiments, diagnostics, and comparative analysis.
• Live Sensor Analysis: Visualize vector changes and monitor live values to pinpoint areas of elevated magnetic strength.
• Device Sensor Diagnostics: Instantly verify the health and status of your device’s magnetometer, accelerometer, and gyroscope.
💡 Practical Use Cases
• Home & DIY: Check magnetic field levels near speakers, power supplies, electronics, and magnets.
• Education & Science: A perfect tool for classroom demonstrations, physics experiments, and research projects requiring data logging.
• Outdoor Adventure: Use the offline compass for orientation on trails where GPS or internet signals may be weak.
⚠️ Compatibility & Important Notes
• Hardware Requirement: This app relies on your device’s built-in magnetometer sensor. If your device lacks this sensor, magnetic measurement features will not function.
• Factors Affecting Accuracy: Readings depend on the quality of your device’s sensor and calibration. Metal objects, thick cases, and nearby magnetic interference can impact results.
• Scope of Measurement: This tool measures magnetic fields only. It does not detect ionizing radiation, radiofrequency (RF) signals (such as Wi-Fi or 5G), or electric fields. It is not a medical device and should not be used for health-critical diagnostics.
Download now to get precise magnetic readings, log your sensor data, and navigate offline with a clean, dependable tool.
