Abstract

Background: The rising prevalence of hypertension is a major global health challenge. As a leading risk factor for cardiovascular diseases, it poses a major threat to human health, making hypertension prevention and management critical public health priorities. Accurate measurement and long-term consistent monitoring are essential for effective hypertension control. With the rapid advancement of internet and innovative technologies, integrating smart blood pressure monitors with dedicated mobile apps has become a prominent trend in blood pressure care. Purpose：This study focuses on the interface design of smart blood pressure monitors and their paired apps, aiming to offer practical insights for optimizing these digital health tools to enhance user acceptance, long-term engagement, intuitive experiences, and the sustainable development of intelligent health management systems. Methods: Adopting case analysis and literature review, three leading Republic of Korean smart blood pressure monitor apps were selected. Key analyses included user interaction processes, information architecture, and GUI elements (layout, color, icons, typography, data visualization). Results: The Omron HEM-7280T and its app feature a well-structured interface with clear information hierarchy, intuitive navigation, and strong usability. In contrast, the InBody BP170B app provides basic functions but lacks in-depth health insights and engagement features. The Biogram LS808-BS app has an overly complex, cluttered layout and insufficient guidance, causing confusion and reduced efficiency. These differences confirm that interface design significantly impacts user experience and management effectiveness. Conclusion: Smart blood pressure monitor design should prioritize both hardware performance and user-centric interface/app design. Given age-related variations in cognitive abilities, usage habits, and technology adoption, user research aligned with actual needs is crucial. Addressing user cognitive load and diverse contexts enables user-centered innovation, improving experience and hypertension control rates for more effective, sustainable blood pressure management.
