Intangible cultural heritage (ICH) is a crucial part of China’s cultural identity. However, ICH museums face issues like limited scale, low visitor engagement, and operational challenges. This study proposes a new framework for designing a personalized cultural and creative APP. By using a user-center design approach and iterative prototyping methodology, it explores the appearance, content, and functionality design requirements of the APP. The framework aims to solve problems such as design homogenization and low sales of ICH museum cultural and creative products, and also points out future research directions.
