*4.1. Mobile Device*

The application was developed using the Android SDK provided by Google and using Java as the programming language. As the development environment, Android Studio was used since the provided tools integrate seamlessly with IDE using the ADT plugin, which allows debugging code in connected devices and in the emulators included.

At all times, we have followed the design patterns specified by Google for our system, using light colors and maintaining consistency with the rest of the interface devices. The guidance is horizontal because of its greater flexibility of space, and display menus are shown in an intuitive way and leading to a partitioning of space in which several graphs simultaneously are appreciated.

During the development of the application, we have the MVC pattern (Model View Controller), which is very useful to separate the operation of the visual layers. All the logic part was programmed in Java and the visual part was defined with an XML layer, later modified and improved by Java.
