Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Different Stages of Change in Desire to Quit Smoking	Assessment of participant's desire to quit by measuring Stage of Change.; The participant will be asked if they are serious about quitting smoking and they can select from the following options: Yes, within the next 30 days; Yes, within the next 6 months; No, not thinking of quitting All data obtained via questionnaires completed by the participants. Throughout the course of the study, if the participant moves from "No, not thinking of quitting" to "yes, within the next 6 months" to "Yes, within the next 30 days" - that is a positive outcome for the participant. If they answered in the reverse, that would be a negative outcome for the participant. In short, becoming more ready to quit is a positive outcome, becoming less ready to quit is a less positive outcome.	3 months (12 weeks) compared to baseline
Primary	Success to Quit (STQ)	Assessment of participant's attitudes towards quitting by measuring Success to Quit.; The participant will be asked If you were to quit smoking right now, how successful would you be? Rating Scale: 1 = Not at all successful, 10 = Completely successful. Higher score is a better outcome for participants, it indicates a more positive attitude towards quitting smoking.	3 months (12 weeks)
Primary	Difficulty to Quit (DTQ)	Assessment of participant's attitudes towards quitting by measuring Perceived Difficulty to staying Quit.; Participant will be asked: If you were to quit smoking right now, how difficult do you think it would be to stay smoke free?

Higher score is a better outcome for participants, it indicates a more positive attitude towards quitting smoking, specifically lower perceived difficulty to quit.	3 months (12 weeks)
Primary	Average Quit Attempts Made Since Using the Pivot Breath Sensor	Assess participant's smoking behavior by measuring Quit attempts. Participant were asked: Since you began using the Pivot Breath Sensor, how many times have you tried to quit smoking?	3 months (12 weeks)
Primary	Change in Cigarettes Per Day (CPD) From Baseline	Assess participant's smoking behavior by measuring CPD. Participant will be asked to enter a number for: How many cigarettes do you now smoke per day, on average? Enter number value.	3 months (12 weeks)
Primary	Point Prevalence Abstinence (PPA)	Assess participant's smoking behavior by measuring 7-Day and 30-Day PPA. Participant will be asked: In the last 7 days and 30 days have you smoked any cigarettes?

Data obtained via questionnaires completed by the participants.	3 months (12 weeks)
Secondary	Feedback on Breath Sensor Setup, Experience and Use	Gather participant feedback on breath sensor setup: Participant is asked: How would you rate the ease or difficulty of getting started with the breath sensor?; How would you rate the ease or difficulty of following the directions on the breath sensor screen?; If you ever got an error on the breath sensor screen, how easy or difficult was it to understand the issue and correct it?; Select one: - Very difficult; - Difficult; - Neither easy nor difficult; - Easy; - Very Easy I did not set up my breath sensor All data obtained via questionnaires completed by the participants.	1 week
