The aim of the study is to explore three healthcare apps, Numa, Ella, and Leia Health, and their affordances in digital healthcare. By applying discourse analysis and discursive interface analysis as primary methods, the study investigates reward and motivation features within these apps, aiming to uncover the norms and assumptions embedded in their interfaces. Theoretical concepts such as motivation affordance, technology affordances, and sociomaterialism are used as frameworks to understand and analyze the results. The interface analysis provides insights into how various affordances, such as functional, cognitive, sensory, and collaborative, shape the user experience in healthcare apps. The results offer an overview and understanding of how user behaviors are influenced by the structure, design, and features of health apps through their digital interfaces, illustrating how the apps provide users with support and information.
