Smartphone Apps for Smoking Cessation: Systematic Framework for App Review and Analysis

Area of Science:

• Digital Health
• Public Health
• Behavioral Science

Background:

• Cigarette smoking remains a leading cause of preventable death.
• Novel smoking cessation treatments are crucial for public health.
• Mobile health apps present potential for smoking cessation support, but their efficacy is largely unknown.

Purpose of the Study:

• Evaluate top-ranked smoking cessation apps from app stores.
• Investigate common features of these digital health tools.
• Assess the scientific basis of smoking cessation support provided by apps.

Main Methods:

• Searched Android and iOS app stores for smoking cessation keywords in July 2021.
• Screened and rated 228 apps using the American Psychiatric Association app evaluation model.
• Analyzed app features, accessibility, privacy, and clinical foundation.

Main Results:

• 31% of apps were non-functional a year later; high app turnover observed.
• Few apps offered evidence-based interventions like cognitive behavioral therapy or peer support.
• Only 12 apps (in 2021) had published studies supporting their efficacy for smoking cessation.

Conclusions:

• Many smoking cessation apps are irrelevant, non-functional, or lack evidence-based support.
• Consumers face challenges identifying effective digital tools for smoking cessation.
• A comprehensive evaluation system for mental health apps is critically needed.
