Orientation and teaching on the use of the mobile app will be carried out by research team. Return demonstration by patients will be performed at the end to ensure they are capable to use the app at home independently.~A minimum of 4-week intervention duration with session lengths of 1 min, 3 days per week is set for this study.~Patients will be distributed a dairy log to record the frequency and duration of mindfulness practice and submit to the researcher on the day of admission.
