About 100 (50 from TMU Hospital and 50 from Wellcome Clinic) current smokers will be recruited who contact smoke cession clinics in teaching hospitals of Taipei Medical University (TMU) and Wellcome Clinic. They will be randomly assigned either to Usual Care (UC) or Usual Care plus 3M4Chan Intervention group (IG). A randomized comparative effectiveness trial will be conducted. Patient will enroll from September 2017 to May 2018. In UC group, the physician provides a brief advice to quit during first consultation, a quit plan template, and medication prescription (Varenicline, Bupropion, Champix, Nicotinell TTS20) as decided by the physician. IG group includes UC plus a mobile App that is programmed to push tailored messages for health concern and readiness to quit, tips for sustaining abstinence, use of interactive self-assessments, helpful cessation information. This group of smokers will benefit from tailored cessation interventions with integrated body weight management elements that take into consideration the prevailing local and cultural influences on diet and levels of physical activity. IG will be continued even after stopping of the UC.

Smoking cessation rate at two months
Smoking cessation rate will be measured as the ratio of the total number of patients who relapsed with total number of patients in their group. Patients will be considered to have relapsed if they fail at least one of their urine cotinine and carbon monoxide tests.
Time frame: Up to 2 months
Smoking cessation rate at four months
Smoking cessation rate will be measured as the ratio of the total number of patients who relapsed with total number of patients in their group. Patients will be considered to have relapsed if they fail at least one of their urine cotinine and carbon monoxide tests.
Time frame: Up to 4 months
Smoking cessation rate at six months
Smoking cessation rate will be measured as the ratio of the total number of patients who relapsed with total number of patients in their group. Patients will be considered to have relapsed if they fail at least one of their urine cotinine and carbon monoxide tests.
Time frame: Up to 6 months
User engagement at an individual level
Engagement at individual level will be assessed based on the rate of read messages by the patients. This is calculated as the quotient between the messages the patients have read, and the total number of messages the system has sent to the patients. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
Engagement at aggregated level - Mobile application rolling retention
The percentage of users still active N days after installation. This is a ratio of the number of users whose last day of activity is past day N to the number of users who could have been active on day N. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
Engagement at aggregated level - Mobile application session length distribution
The session length is defined as the length of time between the start of the application event and the end of the application event. The session length determines the engagement as it is relevant to know how much time patients spend in the app per session. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
Engagement at aggregated level - Mobile application session frequency
The session frequency is a measure of how often each unique patient used the app within a given time interval. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
Engagement at aggregated level - Mobile application sessions per user
A session is one use of the mobile application by a patient. This begins when the application is launched and ends when the application is terminated. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
Engagement at aggregated level - Mobile application return rate
Return rate measures the percentage of patients who return to the app on a specific time after installation. It is measured by cohort group - that is, based on when patients first opened the app. It is calculated as the ratio of the number of users active on a given period to the size of the cohort. This metric will be assessed throughout the observation until its end.
Time frame: Up to 6 months
User quitting attempts
Number of quitting attempts per patient, including the frequency of the quitting attempts.
Time frame: Up to 6 months
User app behavior
It will be measured as the time spent per app section.
Time frame: Up to 6 months
User satisfaction with messages
Patients' answers to a satisfaction questionnaire that will be handed to them at the end of the study.
Time frame: At 6 months after enrolment.
User message ratings
User's votes for each message in a 5 star scale.
Time frame: Up to 6 months
User lifestyle feedback
Comparison of changes in user lifestyle (at baseline and after 6 months) through the combined questionnaire EQ-5D-5L.
Time frame: At enrollment and at 6 months after enrollment
User lifestyle feedback
Comparison of changes in user lifestyle (at baseline and after 6 months) through the combined questionnaire IPAQ for physical activity.
Time frame: At enrollment and at 6 months after enrollment
User lifestyle feedback
Comparison of changes in user lifestyle (at baseline and after 6 months) through the combined questionnaires SF-36.
Time frame: At enrollment and at 6 months after enrollment
Physical activity
The physical activity would be measured as the total time (minutes) of activity per user, retrieved by GoogleFit in the app.
Time frame: Up to 6 months
