The increasing prevalence of mental disorders and their implications for public health have driven the development of technological solutions aimed at therapeutic support. In this context, this study presents the prototyping of a mobile application as a strategy to support medication adherence and the monitoring of emotional aspects during treatment. Based on principles of usability, accessibility, and user-centered design, the prototype simulates functionalities such as recording prescribed medications, automated reminder notifications, dose administration indication, and mood tracking. The information is organized into charts, allowing users to monitor their medication intake regularity and identify mood variations. These records can be exported in a format compatible with clinical use, without diagnostic purpose, functioning as a complementary resource to professional follow-up. Although developed with a focus on mental health, the model shows potential for application in other contexts involving continuous medication use.
