He is currently widely accepted for his ease of adaptation in human activities. Superimposing data and digital information in a real environment for educational, commercial, social, therapeutic, industrial, among others. The objective of this research is to develop an interactive software to mitigate arachnophobia by using the engine and graphic editor of Unity Games, focusing on augmented reality. In this project the agile scrum methodology was used. Because it is based on incremental development. Enabling application requirements and development to be flexible for patients and developers. Obtained as a result of a sample of 16 people, that 93.19% improved equal or greater than 50% in their level of anxiety and fear according to their score obtained in the test FSQ after using the proposed application. While 6.81% obtained a percentage lower than 50% because the use of the application was carried out in times less than 20 minutes per day, causing no significant changes
