Optimizing Flexibility: Redesigning the Fasting Planner for Hirschhausen’s Diet App

One of my first projects after joining MissionMe full-time was a comprehensive redesign of the fasting planner’s user interface for the Hirschhausen Diet app. Guided by user feedback from testing and support inquiries, I introduced features such as customizable fasting intervals, a “cheat day” option, and progress tracking with visual highlights and retrospective overviews.

I also participated in usability tests with both users and non-users, leveraging their insights to refine the final design and deliver a more flexible, user-centered fasting experience.
