 Despite the benefits of app-based interventions, maintaining engagement over time can be particularly challenging. Lack of rapport building may contribute to lower retention rates in technology-based interventions. Further, the available literature suggests that some tools, including technology based tools, may be more beneficial to patient adherence when combined with education or counseling. To investigate this possibility, the investigators will include a study arm P3 that includes P3 and adherence counseling delivered by a counselor through the P3 app.
