This application also makes it easier for buyers to find original quality products from RIAU. But in its use there are still many problems. This research focuses on developing application recommendations by analyzing and redesigning the UI and UX of the Galeri LAM Online Store Application using the Design Thinking method. This method is known as a comprehensive thinking process that concentrates on creating solutions that begin with a process of empathy for a certain human-centered need. There are 5 stages in this method, namely Empathize, Define, Ideate, Prototype, and Testing. Application recommendations are built in the form of prototypes using the Figma application. The prototype that was built was successfully tested on 10 respondents using System Usability Scale (SUS) testing and 76 application prototypes
