 During the course of their use of the program, participants will be asked to provide information regarding three general areas on a regular basis as part of their use of the app: smoking status, adherence to self or physician-directed quit plans including but not limited to medications for smoking cessation and over-the-counter quit aids, and overall user satisfaction. One way that the program assesses these areas involves asking users to answer questions addressing whether or not the user used nicotine in the last 24 hours. At the end of each week, users will also be asked to report their cigarette count for each of the past 7 days, using the standardized reporting technique called the Timeline Followback TLFB Method Assessment Sobell, 1992.
