The components of the intervention unique to the treatment group include: 1) access to the Propeller Health Asthma App on his/her phone, which includes tracking of ICS and SABA usage; 2) receipt of NorthShore Connect physician alerts (these will be sent by the asthma nurse on behalf of the NS physician) if he/she has "poor adherence" ie missed 4 consecutive days of all of his/her controller medication dosages and their sensor has sent heartbeat to application OR "at risk" alerts if a patient transitions to a "not well controlled" or "poorly controlled" status (defined by the NHLBI guidelines); and 3) monthly phone calls with a nurse from his/her asthma doctor's office to review ICS and SABA usage reports (provided by Propeller Health on their Propeller Health dashboard).

The control group will not receive access to view the contents of the Propeller Health Asthma App on his/her phone, NorthShore Connect alerts for missing ICS or overuse of SABA, or for his/her asthma doctor (the asthma nurse will be viewing this information on behalf of the asthma doctor) to view his/her ICS and SABA use on the Propeller Health dashboard until after the 3-month study has been completed.

The patients in the intervention group will have sensors that are "active", so that these patients receive reminders about when to use their inhalers medications.

Use of the Propeller Health Platform in the treatment group in active mode, compared to the attention control group in silent mode, will demonstrate a 20% change in SABA use and/or minimal clinically important difference (three points) change on the ACT and/or change from ACT score ≤ 19 to ≥20, at 3-months. The 20% change in SABA use = 20 point change (e.g. if a participants uses SABA 40% of days over the 2 week run-in period, and they change SABA use to 20% of days during the final 14 days of the active treatment period, that will equal a 20 point change. If SABA use changes from 40% of days over the 2- week run-in period to 32% of days during the final 14 days of the active treatment period, this will not be considered a 20 point change).

Study staff developed a brief survey using open-ended questions (i.e. 20 questions, no scales used, no minimum or maximum scores are applicable) to ask participants and clinicians whether they were satisfied using the Propeller Health Platform Digital Technology. Standardized instruments are not being used.
