The research consists of the development of a mobile application for Android and iOS operating systems, with the main purpose of promoting, strengthening and preserving the indigenous Zapotec language Diidxazá in its variant of San Blas Atempa, Oaxaca, Mexico. Through the application, any user who has little knowledge of the language, can practice through fun and interactive activities without an internet connection. Its intuitive and interactive design shows basic information about the indigenous language and its representation through images, as well as the audio pronunciation of each word. The methodology used is the user-centered design, which allows to understand the needs of the users and thus ensure that they obtain a greater satisfaction and an experience that guarantees the good use of the application. In addition, a modern technological tool such as the Flutter mobile development framework and the Visual Studio Code source code editor were used. As a result, a high-fidelity prototype was obtained, as well as the approval of the users through the usability scale system.
