Smokers’ user experience of smoking cessation apps: A systematic review

Zhang, M., Wolters, M., O'Connor, S., Wang, Y., & Doi, L. (2023).

International Journal of Medical Informatics, Volume 175. (


In this systematic review of the qualitative evidence on the user experience of smoking cessation apps, we determined six key app functions and five key app characteristics that may play a role in the success of mHealth for smoking cessation. In addition to informing the design of new smoking cessation apps which better meet smokers’ needs, our findings can also be used as the basis for planning realist evaluation research of specific apps and creating programme theories that link behaviour change with technology use.

Smartphone App-Based Interventions to Support Smoking Cessation in Smokers with Mental Health Conditions: A Systematic Review

Chen, J., Chu, J., Marsh, S., Shi, T., & Bullen, C. (2023).

Psych, 5(4), Article 72. (


In this systematic review, we meticulously examined the current literature on smoking cessation apps tailored for smokers with mental health conditions. Our findings underscore a notable gap: there is limited evidence to conclusively determine the efficacy of these apps in assisting individuals with mental health challenges to quit smoking. While the impact of these apps on users’ mental health remains largely uncharted, it is evident that apps grounded in research are generally perceived as effective by their users, often employing theory-driven strategies. However, a stark contrast emerges when comparing research-based apps with their commercial counterparts. The former, despite their evidence-based foundations, often fall short in terms of user engagement and appeal. Enhancing the marketability of research-based apps is crucial. Adopting effective naming conventions and aligning with industry design standards can significantly elevate their appeal. Moving forward, there is a compelling case for the creation of smoking cessation apps for this demographic, drawing from both scientific evidence (including established theories and pertinent clinical guidelines) and the best practices observed in popular commercial apps. Future research, particularly randomised controlled trials, should aspire for more robust methodologies, encompassing larger participant cohorts, extended monitoring durations, and a broader spectrum of outcome metrics.

This study highlights the likely positive effects of certain gamification elements such as levels and achievements on short-term smoking abstinence. Although more robust research with a larger sample size is needed, this research highlights the important role that gamification features integrated into mobile apps can play in facilitating and supporting health behavior change.

Smartphone Apps for Vaping Cessation: Quality Assessment and Content Analysis

Sanchez, S., Kundu, A., Limanto, E., Selby, P., Baskerville, N. B., & Chaiton, M. (2022).

JMIR mHealth and uHealth, 10(3), e31309. (


Given the lack of vaping cessation interventions at a time when they are urgently needed, vaping cessation apps are potentially valuable tools. Therefore, it is recommended that these apps apply evidence-based practices and undergo rigorous evaluations that can assess their quality, contents and features, and popularity among users. Through this process, we can improve our understanding of how apps can be effective in helping users quit vaping.

Validation of the French Smoking Cessation Motivation Scale with French Smokers Using a Mobile App for Smoking Cessation

Bustamante, L. A., & Romo, L. (2022).

European Journal of Investigation in Health, Psychology and Education, 12(8), 82. (


Despite some limitations and unexpected findings, this was the first study to assess the degree of smoking cessation internalization in a large sample of French-speaking smokers who had enrolled in a preparation program using a mobile application. The F-SCMS shows consistent results with SDT framework and convergent validity.

The sole purpose of the study was the validation of the F-SCMS. After its validation, the F-SCMS was translated into Spanish and English as part of the smoking cessation preparation program offered by the mobile app Kwit SAS. The entire program was translated into the two languages by an official translator. In the hope that they will be used for research purposes and in future clinical settings, these versions are shared supplementary materials.

Behavior Change Techniques in Popular Mobile Apps for Smoking Cessation in France: Content Analysis

Bustamante, L. A., Ménard, C. G., Julien, S., & Romo, L. (2021).

JMIR mHealth and uHealth, 9(5), e26082. (


The content quality of popular smoking cessation apps in France varied by app type and price. Most popular apps propose in general good quality content but lack implementation of evidence-based BCTs associated with effectiveness on smoking cessation treatment. Further research is needed to evaluate the improvement in the content quality of smoking cessation apps in France.

Self-Efficacy and Motivation to Quit of Smokers Seeking to Quit: Quantitative Assessment of Smoking Cessation Mobile Apps

Rajani, N. B., Mastellos, N., & Filippidis, F. T. (2021).

JMIR mHealth and uHealth, 9(4), e25030. (


The assessed mobile apps positively impacted the self-efficacy and motivation to quit of smokers making quit attempts. This has important implications on the possible future use of digitalized interventions and how they could influence important psychological factors for quitting such as self-efficacy and motivation. However, further research is needed to assess whether digital interventions can supplement or replace traditional forms of therapy.

In France, tobacco consumption is the leading direct cause of avoidable death. Treatments for smoking cessation are available and proven effective. Nevertheless, only 18% of the world's population has access to smoking cessation programs. Among the new means of treatment, digital health (e-health) seems promising, as it would facilitate access to care. We have two main objectives: to evaluate 1) the effectiveness and 2) the satisfaction of users of a mobile application for smoking cessation and maintenance. We conducted a study with a sample of 255 users of the Kwit application, divided into two groups (i.e. users of the paid vs. free version of the application). Each participant answered six questions designed to measure the app's effectiveness and degree of satisfaction. The results showed that 70% of app users declared themselves to be non-smokers, 76% reported no relapses, and 80% felt that the app had played a significant role in stopping or maintaining their smoking cessation. Further results will be presented, along with an analysis of users' verbatim comments. Our study allows us to conclude that this mobile application is interesting and effective for smoking cessation and maintenance over time. The motivational dimension of the tool appears to be an essential element in the effectiveness and satisfaction of users.

This study identified and analyzed smoking cessation apps available in Portuguese. Although fewer in number than the apps available in English, they represent an expansion of this alternative form of smoking cessation treatment. However, the apps found still lack many of the elements recommended to help smokers quit. To this end, smartphone apps need to be optimized to take into account clinical and other evidence-based practice recommendations. If these applications prove effective, they could represent a promising strategy for smoking cessation. It is therefore recommended to develop applications based on smoking treatment recommendations, and to review and evaluate the effectiveness of existing applications.

Game On? Smoking Cessation Through the Gamification of mHealth: A Longitudinal Qualitative Study.

El-Hilly, A. A., Iqbal, S. S., Ahmed, M., Sherwani, Y., Muntasir, M., Siddiqui, S., Al-Fagih, Z., Usmani, O., & Eisingerich, A. B. (2016).

JMIR Serious Games, 2(2), Article e18 (


Gamification holds the potential for a low-cost, highly effective mHealth solution that may replace or supplement the behavioral support component found in current smoking cessation programs. The framework reported here has been built on evidence specific to smoking cessation, however it can be adapted to health interventions in other disease categories. Future research is required to evaluate the generalizability and effectiveness of the framework, directly against current behavioral support therapy interventions in smoking cessation and beyond.
