Abstract

Background: Despite the consistent improvements in awareness, treatment, and control rates of hypertension, the global prevalence continues to increase. The proportion of patients achieving adequate blood pressure control remains alarmingly low. Additionally, while pharmacological adherence among individuals with hypertension is generally high, compliance to non-pharmacological lifestyle modifications—including dietary regulation, weight management, and other behavioral interventions—remains persistently insufficient. Current hypertension management frameworks often lack the capacity to be effectively tailored to patients’ individual lifestyles, thereby reducing the efficacy of comprehensive blood pressure control strategies. Purpose：This study aims to provide scientific and practical design guidance for the development of blood pressure management products tailored to local patients, thereby supporting long-term and effective hypertension self-management. Methods: Three hypertension management apps were selected from the Apple App Store based on screening criteria including download volume, user ratings, and functional completeness. A comparative analysis was conducted focusing on their information architecture at the functional level and five key elements of the graphical user interface—layout, color scheme, icons, typography, and data visualization—to identify characteristic design patterns and common usability issues. Results: The study found that the interface design of Smart Blood Pressure demonstrates high reference value, exhibiting strong usability and a positive user experience. Conclusion: Compared to the apps commonly bundled with commercially available smart blood pressure monitors, the three standalone apps analyzed in this study are better designed for adolescent and middle-aged hypertensive patients, but exhibit insufficient adaptability for older adults. It is recommended that future hypertension management applications incorporate differentiated and personalized user experience designs—tailored to the characteristics and real-world needs of diverse patient groups, such as age, digital literacy, and health status—to improve both usability and clinical effectiveness.
