Mobile medical service based on internet technology has become an important means to optimize resource allocation， and improve medical efficiency and service quality. Mobile mental health technology can be applied to areas such as psychological assessment， symptom tracking and monitoring， psychotherapy and psychological education， etc. However， there are still many problems， including insufficient evidence-based evidence， limited service targets， doubtful professionalism and safety issues. Service developers should actively expand the content and targets of services， constantly explore more acceptable forms of mobile services， promote the standardization of medical data and platforms， optimize and integrate to existing medical service workflow， so as to improve user experience and medical service quality.
