Abstract

This thesis explores the usability and accessibility of the MyCircadianClock app through comprehensive user testing, focusing on a diverse demographic range to assess how different users interact with the app. This research utilized task-based usability testing followed by post-task interviews to capture in-depth feedback concerning the app’s interface, navigation, and functionality. Key findings indicate that while some users were satisfied with the app's concept, others faced significant challenges due to misleading interface elements, insufficient visual accessibility for users with poor vision, and a steep learning curve in food logging processes.

These insights have prompted specific recommendations to enhance the app's design, such as improving the clarity of interface labels, incorporating more intuitive design elements, and offering clearer instructions to facilitate the user experience. The goal of these enhancements is to make the MyCircadianClock app more user-friendly and accessible, thereby extending its utility across a broader user base and improving user engagement and satisfaction.

By addressing these identified issues, the thesis contributes to the broader discussion on digital health applications’ design and usability, emphasizing the need for ongoing user feedback and iterative design processes to meet diverse user needs effectively.
