EMFGuard is a utility application designed for Android devices that allows users to measure electromagnetic fields (EMF) in their surroundings. Utilizing the phone's built-in magnetometer, this app provides readings of electromagnetic waves, metals, and other devices, making it a versatile tool for both casual and serious users. The app features a digital meter and a classic LED needle meter for displaying the magnetic field readings in microtesla (µT) and milligauss (mG), enhancing user experience with visual feedback.

The application is straightforward to use; simply move your phone around to detect EMF radiations in your environment. It's important to note that EMFGuard requires a magnetic sensor to function correctly; if your device lacks this sensor, it will not provide any measurements. Users are advised to avoid using the app near powerful electrical devices to prevent potential damage to their phone. Overall, EMFGuard serves as an engaging tool for those interested in electromagnetism and related phenomena.
