RT Journal Article T1 Assessing the Hands-on Usability of the Healthy Jeart App Specifically Tailored to Young Users A1 Roldán Ruiz, Ana María A1 Merino Godoy, María Ángeles A1 Peregrín Rubio, Antonio A1 Yot Domínguez, Carmen A1 Martins Teixeira da Costa, Emilia AB Background: The widespread adoption of mobile devices by adolescents underscoresthe potential to harness these tools to instill healthy habits into their daily lives. An exemplarymanifestation of this initiative is the Healthy Jeart app, crafted with the explicit goal of fosteringwell-being. Methodology: This study, framed within an applied investigation, adopts an exploratoryand descriptive approach, specifically delving into the realm of user experience analysis. The focus of this research is a preliminary examination aimed at understanding users’ perceived usability of the application. To glean insights, a comprehensive questionnaire was administered to 101 teenagers, seeking their evaluations on various usability attributes. The study took place during 2022. Results: The findings reveal a considerable consensus among users regarding the evaluated usability aspects. However, the areas for improvement predominantly revolve around managing the information density, particularly for a subset of end users grappling with overwhelming content. Additionally, recommendations are put forth to streamline the confirmation process for user suggestions and comments. Conclusion: This analysis illuminates both the strengths of the app and areas ripe for refinement, paving the way for a more user-centric and efficacious Healthy Jeart application.
