Metal Detector PRO - Meter is an iPhone application that allows users to detect metal objects using their device's magnetometer. By exploring their surroundings, users can find nearby magnetic objects such as wires, pipes, coins, speakers, phones, metal screws, keys, computers, and more. The app also enables users to discover magnetic fields and wood studs hidden under walls or plasterboard by moving the device along the surface.

One of the key features of Metal Detector PRO - Meter is the active detection beep that alerts users when the magnetic field limit is reached. The app automatically stores the time and measurement readings, providing a gauge indicating the magnitude of the magnetic field in uT.
