I have most of my asthma under control and I know how my asthma acts: Users' perceptions of asthma self-management mobile app tailored for adolescents.

Asthma continues to be the leading chronic condition among US adolescents. Despite medical advances, many adolescents face uncontrolled asthma mainly due to insufficient self-management skills. Mobile apps pose a promising adjunct to in-clinic asthma care. However, little is known about the usability and effectiveness of such technology. In all, 20 adolescents participated in a 3-month trial to test an asthma app tailored to their age. Qualitative data on adolescents' experience with the app were inquired. Overall, participants thought the app was functional and user-friendly. The majority expressed that the app assisted them with asthma self-management through tracking of asthma status and text reminders to test their peak flow regularly. They indicated external factors that limited app use and suggested improvements to make the app more engaging and appealing to adolescents. The tested app provides a feasible means to assist adolescent in developing self-management skills, tracking disease status, and communicating with healthcare providers.
