Sexual crimes account for a significant proportion of total crimes and originate from various types of offenses. Although smartphone-based applications for preventing sexual crimes have been developed, they have not been extensively analyzed or promoted, resulting in low public awareness. In this study, we analyzed the strengths, weaknesses, and features of the top five applications based on App Store ratings as of January 2023, using reconstructed analysis indicators to identify application components. The components of the analysis indicators were categorized into functionality, informativeness, and design. Functionality included reporting features and user protection functions, informativeness encompassed location information and offender information, and design involved UI and UX. The results revealed that the applications offered various reporting methods in the functional area and useful features in the informative area, such as providing offender information and real-time safe route guidance based on the user's location. However, they were limited due to their availability in specific regions only. In the design area, the applications were designed to align with their characteristics but presented some usability issues. The findings of this study are expected to serve as a reference for the development and promotion of domestic mobile applications for the prevention of sexual crimes based on smartphones.
