This study aims to analyze the influence of User Experience (UX) design on user ease in using the Tix Id application, a popular online ticket sales platform. The research method used is a combination of descriptive analysis and case studies. Data was collected through an online survey targeting active users of the Tix Id application. The survey includes questions about UX aspects, such as navigation, interface design, responsiveness, and user satisfaction. In addition, in-depth interviews were also conducted with a number of users to gain a deeper understanding of their user experience. The research results show that UX design elements, such as an aquarium layout, easy navigation, and application responsiveness, significantly influence the user's ease in using the Tix Id application. Users who are satisfied with their experience are more likely to use an app on an ongoing basis and recommend it to others.
