This study developed a smartphone application (app), based on user demand, for the self-care performance of patients with chronic Hepatitis B. The smartphone app was developed in five stages. In the analysis stage, we surveyed the demand for the app among 187 patients with chronic Hepatitis B, analyzed several other apps, and conducted a literature review. In the design stage, the app’s purpose was established, and the necessary functions, system interface, database, and screens were designed. In the development stage, the app was developed. In the implementation stage, the master version of the app was used by four specialists and five participants with chronic Hepatitis B. In the evaluation stage, we conducted a heuristic evaluation and a mobile app rating scale evaluation, with these nine subjects. As a result of the evaluations, 19 aspects of the system were modified to further improve the app. This smartphone app is expected to be helpful in performing self-care, serve as a disease-related knowledge source, and promote self-efficacy in chronic Hepatitis B patients.
