ASTHMA
Of the 38 DAP connections, 5 (13%) failed to establish severity owing to inconsistencies (limitation for delivery at scale). These 5 connections were identified when the participants or parents reported DAP use, but no connection was recorded in the app. Furthermore, 33 connections to the app for 27 exacerbations were recorded, 9 by parents for 8 exacerbations and 24 by adults for 17 exacerbations. The median number of descriptors entered into the app was 5 [At connection, the app classified the exacerbation as mild in 12 cases, moderate in 11 cases, and severe in 10 cases. Two examples of advice provided by the app are given in Median symptom severity self-evaluated by the participants on a 10-point scale before recording the symptoms in the app was 4 [Symptom severity as evaluated by the participants and by the app. Before recording the symptoms of asthma, the participant or parent recorded the symptom severity in the app (see the Methods section: from 0=no exacerbation to 10=maximal severity).

Severity as assessed by the participants or parents was consistent with the severity as assessed by the app (3-group comparison using the Kruskal-Wallis test:
