Authors - Humberto Merritt Abstract - In recent years, the use of digital applications for data management, information access, communication and resource exchange has grown worldwide. Advances in telecommunications have been particularly pervasive in Mexico, where the widespread use of smartphones has encouraged the adoption of digital technology. In this study, we examine the implementation of the APP CDMX electronic platform, which was designed to enhance Mexico City's functionality. The research aims to determine how this tool has helped citizens learn about available public services and how they evaluate it. In particular, the research describes how smartphone users are leveraging the application to access real-time data on local procedures and their fees, the traffic conditions, specific transit routes and stations, and other touristic venues, thereby achieving not only more efficient mobility but also encouraging a sustainable lifestyle. Using a qualitative methodology based on the lexical analysis of user opinions and adopting a multidisciplinary approach, the study concludes that the APP CDMX has positively transformed citizen interaction, accelerating administrative processes and democratizing access to key information.
