What this trial studies

This randomized controlled trial will assign 1,410 adults in various stages of recovery to either access the Pink Cloud mobile app or to an active control condition, with follow‑up assessments at 1, 3, and 6 months. Pink Cloud offers access to over 245,000 in‑person and virtual 12‑Step meetings plus tools such as a sobriety counter, daily planner, and personal inventory to support recovery. Primary outcomes are number of days sober and frequency of drug and alcohol problems, with secondary outcomes tracking meeting attendance, proportion of sober people in the participant's social network, and engagement in recovery activities. Participants must own a smartphone and be willing to attend peer or 12‑Step meetings while not currently enrolled in outpatient or residential treatment.
