This simple app turns your Android phone into a Magnetic Field Meter App.
To use this app the user just clicks the 'Magnetic Field Meter' app icon and they are taken right into the app. They are greeted with a graphic in the middle of the app with the microtesla units (µT) its reading as the app starts. The demo is shown on an acutal device because this does not work on a simulator. As the phone was moved around in different directions it was picking up readings that went up and down. Examples are shown below of the App in use in both Video and Screen Caps below.
