This app uses your device's built-in magnetometer to detect and measure magnetic and electromagnetic fields. It can help you locate ferromagnetic metal objects like wires, pipes, coins, and keys, as well as discover hidden wood studs behind walls or plasterboard.
The app leverages your device's magnetic sensor to quantify the intensity of the magnetic field. When placed near ferromagnetic materials, these fields cause a disturbance, leading to an increase in the readings displayed by the app. An active detection beep alerts you when a certain limit is reached.
No, this app is intended for private and entertainment purposes only. While it can detect magnetic fields and metal objects, it is not a substitute for professional-grade metal detector devices.
Key features include active detection beeps, automatic storage of time and measurements, and a gauge displaying magnetic field magnitude in both microteslas (μT) and milliGauss (mG). It also allows for the discovery of hidden wood studs behind walls.
The app is useful for construction workers and handymen looking to find hidden wires in walls, students for educational projects and experiments, and anyone interested in exploring magnetic fields. Scientists, teachers, and engineers also use detector meters for similar purposes.
