[EN] Companies in the world are incorporating new technologies to the management of their corporations. Smartphones are now a work tool that complements the computers. Consequently, many companies have developed their own software, for their own clients to allow them to get to their services without being at home, and for their employees too, to let them have more mobility and to optimize their job. The internship made by the student in a company related to the biomedical sector, called Electromedical S.L., has promoted the development of this Trabajo Fin de Grado (TFG). In this project, a software tool has been developed to the Android operating system, made with the environment of MIT App Inventor and with a database (dynamic tables of Google Drive) that has to be used by the employees of the company to solve a problem: Electromedical S.L. is a distributor of medical devices that offers technical assistance too (SAT). While the sales department handles the distribution, the technical department manages the SAT. The mobile application is aimed at substitute some forms called work orders. The technician must fill in these forms to make the client know what they have made. Besides, due to the devices that are distributed by the company, it must draw up a report to the Consejo de Seguridad Nuclear (CSN) specifying all the reparations they have made. That is why it is important to have clear information. Digitalizing the work orders and having the information in the cloud, ensures that the company fulfil their legal obligations with the CSN, because it is not possible to lose some information missing papers. Furthermore, it makes the technicians to make their job comfortably, because they do not have to bring printed work orders with them. This is especially important because their job includes many displacements. Additionally, with this new application, paper’s consume is reduced by the company, so it will reduce company’s expense and help to preserve the environment. TFGM
