The UI of human-computer interaction users became UI due to the manipulation of the code by visual experience and is the result of combining design and psychology. If you look at many apps in the market now, negative minds about apps exist universally because the UI display is not clear, the UI is not sophisticated, and the interaction design is not useful. Therefore, it is very important to satisfy people with simple design and refined UI. This study analyzes UI design against Korean and Chinese mobile navigation apps. The advantages and disadvantages of the UI design of mobile navigation apps are compared and analyzed, and four representative mobile navigation apps of Korea and China were selected respectively as a research method to express visual information of Korea and China's mobile navigation systems, comparing and analyzing colors, icons and layouts, and many research studies, references, and books. Using four elements, analyze the navigation app in detail and organize the analysis results. This study will compare and analyze the main screen of the navigation app. Through this study, I hope that users can improve convenience and efficiency in the process of use by making suggestions to navigation app companies that will later enter the market. The analysis of interface design allows the frame to be implemented more clearly.
