The development of the Internet and technology has changed people's work and life, and people's work efficiency has been improved, while sleep disturbance has become increasingly prominent. Affected by electronic products, young people are in the state of poor sleep quality and sleep delay, and the age of sleep disturbance group is gradually younger. In this regard, designing sleep management APP to guide and intervene people with sleep problems and help them get better sleep is a work of both significance and market application prospect.

The main methods used in this project include literature research and qualitative research. Firstly, the origin and development of persuasion theory are sorted out, and secondly, the design practice of sleep management apps and their influence on people are sorted out. Through observation, statistical analysis of data and other ways to conduct multi-angle and all-round user research and market research, understand the causes behind sleep delay and sleep disorders, and find the design core of the project. In addition, as this project is essentially an interactive app design research on human behavior and psychology, which combines theory and reflective practice and is divided into three stages in an orderly manner, it will also involve human-centered design methods and reflective practice research methods.

Overall, iSleep is a mind-body health app that focuses on users' sleep, music and healing. The app provides a vast amount of audio content such as talking books, listening to music and white noise to help users take a break from the fast-paced present and enter another calm and quiet time and space - reducing anxiety, staying focused and calm, and relaxing their thoughts for better sleep. In addition, there are two unique features, sleep data analysis and setting specific music alarms, allowing users to have a clear picture of their every sleep.
