Self-management methods for chronic diseases using mobile phone and tablet applications have recently become popular. Although several applications for asthma management are available, there are no reports concerning the long-term treatment effects of inhaled corticosteroid (ICS)/long-acting beta agonist (LABA) treatment on diurnal peak flow variability according to digital asthma diary records or its utility. A 31-year-old female diagnosed with moderate persistent asthma was treated with ICS/LABA. On approximately 2 years after the treatment, we were able to observe that diurnal peak flow variability disappeared gradually and completely when the time axis set that all records can be observed in one screen. Self-monitoring the peak flow using digital asthma diaries is suitable for long-term recording and allows an adequate understanding of long-term asthma state and treatment effects especially for minor diurnal peak flow variability by ICS/LABA.
