The purpose of this work is to promote the learning of children's literature in primary school students, from the creation of an interactive application that contains various literary texts that facilitate the improvement of understanding, interpretation and critical thinking in said students. Students have changed from studying in a library with paperback books to sitting in front of a computer or cell phone using the internet to do their homework and commitments. Regarding reading in students, children usually do not have enough money to buy an original book, as a consequence they end up downloading digital documents on Internet pages that are not necessarily legal and/or simply looking for the summary of the book they need for taste or commitment. The application that we developed, which is called leo, and launch to the public the teachers in training of this research, seeks to be an application that allows readings that reflect an improvement in the omprehension and interpretation of the text by of these students. It is, therefore, one of our goals, to capture the attention and interest of the child and achieve motivation for reading through multiple tools that provide interactivity between the text and the reader. These tools will give the student the possibility of obtaining a setting with sound effects, as well as a voice-over that allows them to get involved in reading and finally achieve an autonomous improvement in reading comprehension in each of the elementary school students. It was decided to apply the surveys to the students corresponding to a first and third grade classroom of the Aurelio Martínez Mutis Educational Institution, site B. In which we have the availability of 50 elementary school students in the Spanish area.
