1. Introduction
Smoking remains a pressing global public health concern, claiming millions of lives annually [1] . Despite widespread awareness of its detrimental effects, breaking free from smoking’s addictive grasp continues to challenge approximately 1.3 billion individuals worldwide [2] [3] . While various strategies, including public health campaigns, pharmaceutical interventions, and mobile health (mHealth) applications, have been implemented to address this crisis, their effectiveness is hindered by certain limitations [4] . Public health campaigns and pharmaceutical interventions, such as Nicotine Replacement Therapy (NRT) and prescription medications, have made strides in raising awareness and aiding cessation efforts. However, NRT faces obstacles like side effects and user non-compliance, while prescription medications may have contraindications and potential side effects [5] . The recent surge in technology and smartphone use has introduced novel opportunities for smoking cessation interventions. Although mHealth applications show promise, their efficacy varies, and user engagement remains a challenge [6] [7] [8] . Many existing apps lack personalization and interactive features, limiting their ability to sustain user interest and motivation [7] . Here in lies the potential of persuasive technology—an approach rooted in leveraging psychological and social triggers for behavior change [8] . Successfully applied in various fields, persuasive technology’s principles have fostered healthier habits, environmental responsibility, and education [9] [10] .
Despite its success in other domains, applying persuasive technology to smoking cessation remains largely unexplored. Existing mHealth applications for smoking cessation encounter issues such as failure to induce sustained behavior change, low user engagement, and a lack of evidence-based strategies [11] . Additionally, these apps often lack intuitive interfaces, hindering user adherence and effectiveness [12] [13] . Furthermore, they frequently neglect the unique challenges faced by diverse populations, including adolescents, pregnant women, and individuals with co-occurring mental health conditions [14] .
To address these gaps, this paper endeavors to develop an innovative, user-centered mHealth application for smoking cessation, harnessing the power of persuasive technology. The research goals encompass identifying effective persuasive techniques, understanding user needs and preferences, and designing and evaluating a prototype app to enhance user engagement and effectiveness.
This paper’s contributions extend beyond public health, influencing efforts to reduce smoking rates and advancing the application of persuasive technology in health behavior change. Moreover, it offers insights for the technology industry, guiding the development of more user-centered and effective digital health interventions.
2. Literature Review
2.1. The Concept of Persuasive Technology
Persuasive technology is a sub-field within the broader domain of Human-Computer Interaction (HCI) [1] . This term refers to a class of technology intentionally designed to change users’ attitudes or behaviors without coercion or deception. Essentially, these are digital systems, applications, or products that seek to shape, reinforce, or change a person’s behavior or thinking by providing information, incentives, reminders, or suggestions. The technology employs several techniques to achieve its objectives, including the use of positive reinforcement, social pressure, and reminders. The concept of persuasive technology was introduced by B.J. Fogg, a professor at Stanford University, in the early 1990s. His work was inspired by the intersection of psychology, especially social psychology principles, and computer science [2] [3] . Fogg noticed the potential that computers and digital systems presented in influencing human behavior and decided to explore this path. Over the years, persuasive technology has evolved with advancements in technology, resulting in a wide array of applications, including websites, mobile applications, games, and more recently, virtual and augmented reality systems. Central to understanding persuasive technology is B.J. Fogg’s Behavior Model [4] . According to this model, three elements must converge at the same moment for a behavior to occur: motivation, ability, and a prompt (or trigger) [4] . Motivation refers to the desire to perform a behavior, ability refers to the capacity to execute the behavior, and triggers act as cues to action. For a persuasive technology to be effective, it must enhance the user’s motivation to change, increase the ease or ability to perform the desired behavior, and provide timely triggers.
Another important concept in persuasive technology is User Experience (UX) [5] [6] . The user’s experience when interacting with the technology is crucial in determining its efficacy. If a user finds an app difficult to navigate or unappealing, they’re less likely to engage with it, thereby diminishing its persuasive potential. Therefore, UX designers play a pivotal role in making persuasive technology effective, appealing, and user-friendly. Persuasive technology can be classified into various categories based on several factors such as the persuasion context, the technology type, or the persuasion strategy employed. For example, some technologies are focused on promoting health and wellness, like fitness tracking apps that encourage users to be more physically active [7] . Others might aim to foster sustainable behavior, like apps that provide feedback on energy consumption to promote conservation [8] [9] [10] . The importance and impact of persuasive technology in our society cannot be overstated. In our digitized world, we increasingly rely on technology for a wide range of activities, and the ability to leverage this technology to drive positive behavior change can have far-reaching impacts. Persuasive technology can support education, foster health and wellness, encourage sustainable living, and so much more. Indeed, as we continue to unravel its potential, the role of persuasive technology in shaping our behaviors and attitudes is becoming more critical [11] [12] [13] .
2.2. Persuasive Technology and Smoking Cessation
Persuasive technology plays a significant role in smoking cessation, one of the most challenging public health issues [14] [15] . The utility of this technology in the fight against smoking stems from its ability to provide smokers with real-time, personalized support during their journey to quit smoking. By leveraging a combination of motivation strategies, ability strategies, trigger strategies, social support strategies, and tailoring strategies, persuasive technology can deliver powerful smoking cessation interventions [16] [17] . Motivation strategies are designed to boost the smoker’s desire to quit. This could involve providing instant feedback on health improvements or money saved since quitting, or gamification elements like challenges and rewards to make the process more engaging [18] [19] . For example, an app might award badges for reaching certain milestones (e.g., 24 hours smoke-free), turning the journey into a rewarding game. Ability strategies aim to make it easier for the smoker to quit. This could involve providing educational content about smoking and quitting techniques or tracking features that allow the user to monitor their progress. By empowering the user with knowledge and self-awareness, these strategies increase their ability to successfully quit. Trigger strategies involve delivering prompts at the right moments to nudge the user towards desirable actions. This might involve sending push notifications with motivational messages or reminders to resist cravings [20] . These triggers can provide the extra push needed in moments of temptation. Social support strategies leverage the power of social influence and support in behavior change [21] [22] . This could involve features that allow the user to share their progress with friends or join online communities of people who are also trying to quit. Feeling supported and understood can significantly boost motivation. One example of a smoking cessation app that employs these strategies is Smoke Free. This app provides users with progress tracking, instant feedback on health and financial gains, daily challenges, and the ability to share progress with others [23] . It also uses personalization, tailoring its support based on the user’s smoking habits and reasons for quitting [24] . The benefits of using persuasive technology for smoking cessation are numerous. It allows for the delivery of real-time, personalized support, which can be more effective and engaging than one-size-fits-all interventions. It also allows for scalability, reaching a large number of smokers at a relatively low cost. However, there are also challenges. Maintaining user engagement over the long term is a common challenge in digital health interventions, and smoking cessation apps are no exception. Ensuring that the content is accurate and effective is another significant challenge, as is ensuring user privacy and data security [24] . The effectiveness of persuasive technology in smoking cessation has been demonstrated in multiple studies. For example, a study published in the journal Addiction found that smokers who used a cessation app were more likely to quit than those who did not [25] [26] . However, more research is needed to determine which specific features and strategies are most effective and how these technologies can be optimized.
2.3. Overview of Smoking Cessation Apps, Websites, and Software
In today’s digital age, where health and technology increasingly intersect, numerous tools and platforms have been designed to aid individuals in their fight against nicotine addiction. These smoking cessation platforms exist in various forms, including mobile applications, websites, and software, all aimed at providing comprehensive support to individuals during their quit journey. They employ different strategies such as behavioral therapy, gamification, community support, progress tracking, and health benefit information to keep users motivated and informed. By offering immediate access to resources, they enhance the user’s ability to maintain a smoke-free lifestyle and improve their overall health.
The world of smoking cessation platforms is diverse, and each one offers unique features and methods to assist users in their quit journey. The following table presents a comparison of six popular smoking cessation apps, websites, and software available on both the Apple Store and Google Store. These platforms are compared in terms of support groups, health benefits, progress tracking, feedback, gamification elements, volunteering to caregivers, and advertisements.
Upon reviewing the comparison presented in Table 1, it becomes evident that the majority of platforms place significant emphasis on progress tracking and feedback. Notably, platforms such as EasyQuit, Quit Genius, and Smoke Free [27] [28] stand out for offering both features, underscoring their commitment to providing real-time updates and tailored advice throughout a user’s quit journey. Additionally, Kwit introduces gamification elements [29] , reinforcing user progress through rewards and potentially enhancing motivation for smoking cessation.
However, the analysis reveals a notable gap in the comprehensive provision of health benefits, a crucial aspect of smoking cessation, as only EasyQuit addresses this aspect. This gap suggests an opportunity for improvement in delivering health information that could serve as a motivational factor for users seeking to quit smoking. Furthermore, the inclusion of support groups is limited to only two platforms—Quit Genius and QuitNow! While the social aspect is recognized as significant in smoking cessation, its underutilization across platforms raises questions about the potential benefits of fostering a sense of community.
Lastly, the lack of a feature allowing users to volunteer information to caregivers is a noteworthy observation, pointing to an area for potential expansion and the involvement of external support in the quitting process.
