All participants were recruited through social media and were screened and consented online. After enrolling, participants received a link to the baseline survey which asked about past and current tobacco use, nicotine dependence, motivation to quit, cognitive dissonance and demographic information. All participants were assigned to an online support group of 5 or 6 people. The group received simultaneous invites to the app so they were able to move through the 25 day program together. The app contained short videos of a CoQuit facilitator who presented instructions for specific tasks, such as writing a brief letter to a friend or family member explaining their commitment to stop smoking. Participants recorded videos of themselves related to these activities and posted the videos within the app where they were viewed by other members of the group.
