There remains a significant gap in the literature concerning the establishment of a China-ASEAN art platform and the development and application of related software. This article introduces and critically analyzes the importance and feasibility of the China-ASEAN art platform. It creatively presents the newly developed mobile phone app: China-ASEAN Art. We evaluate the entire design and development process, from initial ideation to the final concept, providing a detailed introduction to its functions. Our research adopts a rigorous mixed-methods approach, including designer surveys, questionnaire surveys, depth interviews, and content analysis of a new responsive online platform. Our findings indicate that smartphones have become inspirational tools for artists' creative work. Aimed at supporting artists, the app allows users to log in as "USER" mode, enabling them to browse art news, visit exhibitions online, conduct art transactions, record impressions and comments, and incorporate art appreciation into their leisure time activities.
