An analysis of the current methodologies used in the teaching of Calculus at the university level shows that these are insufficient, especially in the teaching of mathematics courses. That is why the author proposes a teaching methodology based on a mobile application to graph mathematical functions, which he has called the Algeo Method, presenting it as an attractive methodology both for students with learning difficulties and for those who already have a level of skill in the subject.The Algeo Method, applied to the subject of Calculus, allows engineering students mainly to consolidate their knowledge in the areas of Differential Calculus and Integral Calculus.
