The limitations of educational services in regular basic education are a frequent problem that affects the quality of teaching, and in the cities of the Peruvian highlands, due to the scarcity of learning materials or instruments adapted to Andean mother tongues, among them the Quechua language, this contributes to the weakening of the cultural identity of the indigenous populations of the department of Ayacucho, located in Peru. This paper presents the results of a study about the use and effects of the mobile application 'Warma' (Warma, means 'child' in the Quechua language of Ayacucho), as a tool for learning language and mathematics in Quechua-speaking educational institutions in communities near the city of Huamanga (Ayacucho, Peru). This study corresponds to the continuation of a previous experience, which took place during the year 2019, and in which children from educational institutions of Quechua-speaking indigenous communities located in the city of Ayacucho participated. The results show that the use of the mobile application is superior to traditional teaching methodology in the process of learning language and mathematics, indicating that the use of mobile applications has a favorable effect on the teaching of indigenous languages, such as Quechua, in both rural and urban educational institutions.
