Patients received smartphones and training to use the COPD Co-Pilot application.  The primary endpoint was time to clinical recommendation (TTCR) from a symptom alert; adherence to completing daily symptom reports through the COPD Co-Pilot application and patient satisfaction were also measured.


 Average COPD Co-Pilot adherence overall was 75.2% (95% CI 74.6-75.9).  The COPD Co-Pilot tool was associated with relatively high levels of adherence, suggesting patients' willingness to monitor symptoms daily.
