Abstract:
Maintaining healthy eating habits is essential for the overall health and well-being across all ages. While mobile dietary applications offer assistance, their complexity of meal logging and often poor design limit widespread adoption. This study presents the development of a mobile application, named LogYourEatingHabits, which is designed to simplify meal logging and emphasize both meal content and eating patterns. Emphasis was also placed on ensuring high usability and accessibility in the application, making it usable by as many user groups as possible. Using a user-centered design approach, the application was iteratively developed and improved throughout feedback from 16 participants over five iterations. Each iteration provided new insights, leading to enhancements such as more consistent design and interaction of user interfaces, and increased intuitiveness and user-friendliness. The System Usability Scale (SUS) scores showed improvements across iterations, and together with o
bservation and interview findings, they indicated overall high perceived usability. Future works include expanding the food database, optimizing the image recognition feature and providing personalized feedback based on data gathered within the app.
