Smartphone App for Asthma Self-care: Assessment of Outcomes (Asthma Progession and Costs)

The goal of this clinical trial is to investigate whether a smartphone app based on the Global Initiative for Asthma (GINA) guidelines can improve asthma control and quality of life, and decrease asthma-related costs in children. The main question it to answer whether this app can improve asthma control, increase the quality of life, and decrease asthma-related costs. Participants in the intervention group downloaded the asthma smartphone app, and followed up monthly via phone calls and clinic visits, while the control group received reminder calls. Researchers will compare with the control group to see if the intervention receives more asthma control improvement.
