Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators will study the use of a home-based spirometer (Spirobank Smart spirometer) that connects to a smartphone app (VitalFlo) in teenagers with persistent asthma to determine if clinically significant changes in lung function detected by the spirometer are associated with patient-reported asthma symptoms.
