A metal detector is a device that can be used to detect the presence of metals such as iron, steel, and other elements that have a magnetic property. These elements are found in many different things in the environment, such as walls, floors, bodies, etc. The detector is able to detect the elements by measuring the magnetic field. 

The most important advantage of the metal detector app is that it is very easy to use. The user can simply move the device in the search area and look at the readings. 

The first time you run the application, you will find a short description of how to use the app. After that, just move your device in the search area and look at the readings. The increasing of the numerical readings and the changing of the color of the frame from green to yellow or red indicate a field with metal objects. 

For added comfort, when metals are detected, the application emits a sound, and a graph of measurements is built in the measurements’ history.
