The purpose of this pilot study was to assess the feasibility and user engagement of an app tailored to help daily smokers reduce or quit cigarette smoking. All participants received a preliminary version of the application on a phone. We hypothesized that participants would use all the features available on the application, complete more than 70 percent of the Ecological Momentary Assessments (EMA’s), expect videos to be utilized by over 80 percent of the sample, and post-intervention feedback will result as generally positive. We recruited 15 daily smokers (40.0 percent female; mean age; 46.5; SD: 13.3; age range 18-65 years) who were screened using a web-based system. Those eligible were scheduled for a baseline visit at The Anxiety and Health Research Lab/Substance Use Treatment Clinic. Participants returned the phone at the 4-week post quit follow-up, totaling 6 weeks of use. Interactions with the application were recorded for descriptive analysis. The results of the study reflect that participants had completed over 73.5 percent of EMA’s, all videos were utilized by over 80 percent of the sample, every participant utilized available features, and self-reports indicates a positive experience regarding EMA’s utility and overall experience with the application.
