Summary

This study tested whether a mobile app that lets people with asthma report their symptoms between doctor visits can improve their quality of life. Over 400 adults with asthma used either the app or received usual care. Researchers measured changes in asthma-related quality of life and healthcare use over 6 to 12 months.
