EMF Finder - Detect EMF Signal 1.6

This application transforms your smartphone into a tool for detecting electromagnetic fields (EMF), utilizing the device's built-in magnetic sensor. While innovative, its practical effectiveness depends heavily on the hardware capabilities of your device and the environment in which it is used.

Key features include real-time EMF monitoring, both digital and analog meter displays, and live data visualization through graph views. The application also provides sound alerts for significant EMF fluctuations and allows sensitivity adjustments and calibration to optimize measurements. It operates offline and offers a dark mode for user convenience.

The underlying principle involves the device's magnetic sensor detecting variations in electromagnetic fields, which are then represented visually and audibly within the application. Readings are expressed in microTesla (µT), a standard unit for magnetic field strength.

Detection range varies according to hardware specifications, typically between 15cm and 25cm, with sensitivity contingent on the quality of your phone’s magnetic sensor. Devices equipped with a magnetometer tend to provide more reliable results.

The app offers multiple measurement modes: a traditional meter view with a needle gauge, a live graph of signal fluctuations, and a precise digital readout of µT values. Calibration features are included to improve accuracy based on individual device performance.

Potential use cases span from identifying hidden EMF signals and locating electrical wiring behind walls to educational applications for students and professionals conducting preliminary surveys. It serves as a quick diagnostic tool for engineers and researchers exploring electromagnetic phenomena.

However, it is important to note that this application relies entirely on the device’s magnetic sensor, which may not be supported by all models. Devices lacking a magnetometer will be incompatible with its features.

To enhance measurement reliability, manual calibration options are provided, acknowledging that sensor quality can cause variations in readings across different devices. The app is designed to be lightweight and energy-efficient, minimizing impact on battery life during extended use.

This tool is intended for general and educational purposes only; it is not suitable as a specialized scientific instrument. Users should interpret results cautiously, understanding that accuracy depends on hardware specifications.

The developer supports ongoing maintenance through advertisements within the app to offset operational costs.
