Abstract
Create products with accessibility is a way of reaching a greater number of users and especially encourage the inclusion of users who have some disability, something increasingly important. This was the prerogative for the process of creating an application: to enable users with some vocal, auditory and mainly visual limitations to have an experience similar to that of ordinary users. In this article, we present the process of creating a new version of an application that had no accessibility at all.
