The aim in this project is to expound the development of an application, which is going to be used in both cars and mobile devices, in order to improve the driver’s fuel consumption while driving as well as to compare the obtained results during the run or a finite interval of time. This application is going to be implemented with Android. Also the project content includes the process description to create it, and it’s planning for development. As a result, the user, with the help of specific graphs, is going to be able to minimize his fuel’s consumption without having to modify any component of the car, only with a slight change in his way to drive.
