About this app

Measure magnetic fields accurately and navigate with confidence—this multifunctional sensor toolkit turns your device’s built-in magnetometer into a precise EMF/magnetic field meter and a reliable offline compass. Designed for research, DIY projects, and outdoor use, it delivers clear, real-time readings and practical tools without gimmicks.
Core features
• EMF/Magnetic Field Meter (Gauss Meter): View 3 axis (X/Y/Z) magnetometer data in microtesla (µT) with real time updates to assess magnetic field strength around you.
• Compass Sensor (Offline): Use a dependable, on device compass for navigation without mobile data or Wi Fi—ideal for hiking, camping, and fieldwork.
• Real-Time Analysis: Monitor live magnetic field values and vector changes to help pinpoint areas of elevated field strength.
• Alerts & Thresholds: Set custom µT limits and receive notifications when the magnetic field exceeds your chosen threshold.
• Data Logger: Record magnetic field readings over time and review detailed logs directly in the app for experiments or diagnostics.
• Sensor Diagnostics: Check the presence and status of key sensors (magnetometer, accelerometer, gyroscope) on your device.
What you can do
• Check magnetic field levels near electronics, speakers, power supplies, or magnets.
• Run simple science experiments, classroom demos, and DIY measurements.
• Use the offline compass for basic orientation on trails or in remote areas.
Why it helps
• Accurate, on device measurements using your phone’s magnetometer sensor.
• Clear, actionable data (µT, 3 axis) for investigations and field checks.
• Practical tools in one place: magnetic field detector, gauss meter, compass, logging, and alerts.
Notes and compatibility
• Requires a device with a built in magnetometer for EMF/magnetic field measurements.
• Results depend on sensor quality, calibration, and nearby interference (metal objects, cases, magnets).
• Measures the magnetic component of EMF only. It does not measure electric fields, radiofrequency (RF) signals (e.g., Wi Fi, microwave ovens), or ionizing radiation, and it is not a medical or safety instrument.
Get precise magnetic field readings, log your data, and navigate offline—all in one clean, dependable sensor app.

Ads make it unusable. Literally could load any applications because the ads kept freezing. Unusable.

The app forces you to give 5 star rating even before you start using it. Every click opens an advt first before anything happens.
