Interventions

• Pink Cloud — BEHAVIORAL
  Participants randomized to the Pink Cloud condition will receive a subscription code to access the Pink Cloud mobile application for approximately 365 days. The app includes features such as a searchable database of over 245,000 12-Step meetings (in-person and virtual), a sobriety counter, customizable daily planners, personal inventory tools, and a resentment journal. Participants are encouraged to use the app as they see fit throughout the study period. No prompts or required usage schedules will be imposed; instead, engagement will be self-directed to reflect real-world usage patterns.
• Active Control — BEHAVIORAL
  Participants randomized to the control condition will receive a code to access recovery-related resources hosted on a private study website. These materials include links to mutual-help groups, crisis support services, and educational content and treatment options. Participants may access the website at their discretion and engage with the resources as often and in whatever ways they choose. No prompts or required usage schedules will be imposed.

Study Details

This randomized controlled trial (RCT) will evaluate the feasibility and efficacy of Pink Cloud, a mobile health application designed to support recovery from substance and alcohol use disorders (SUD/AUD). The app provides access to over 245,000 in-person and virtual 12-Step meetings, along with features such as a sobriety counter, daily planner, and personal inventory tools. In this study, 1,410 participants in various stages of recovery will be randomly assigned to receive either access to the Pink Cloud app or to a control condition. Participants will complete follow-up assessments at 1, 3, and 6 months. Primary outcomes include number of days sober and frequency of drug and alcohol problems. Secondary outcomes include meeting attendance, proportion of sober individuals in one's social network, and engagement in recovery-related activities. The investigators hypothesize that participants in the Pink Cloud group will report more days sober and fewer substance use problems than those in the control group, and that they will also report attending more meetings, having a greater proportion of sober peers, and engaging more frequently in recovery activities.

Participants can integrate the app into their recovery efforts as they see fit throughout the study period.
• Active Comparator: Active Control
  Participants in this arm will receive access to a website containing curated recovery-related materials. These resources are intended to offer general support for individuals in recovery, without emphasizing any specific program or approach. Participants are free to explore and use the content as they choose.
