Users are prompted to create this quit plan the first time they open the app. The three-category main menu of quitting strategies (see screenshot in Figure 1) includes Staying Motivated, Having an Urge, and I Slipped. Each of these menus contains ACT-specific exercises that are designed to enhance commitment to quitting by exploring and evoking values (Staying Motivated), enhancing willingness to feel an urge to smoke and let it pass (Having an Urge), and building self-compassion as an adaptive response to the experience of slipping up and smoking during a quit attempt (I Slipped). Exercises are presented as short video or audio, and all are accompanied by a text transcript.
