With the advancement of smart elderly care policies and the growing demand for digital health management among older adults, the need for accessible healthcare solutions is becoming increasingly urgent. Age-friendly medical applications play a pivotal role in bridging elderly users with healthcare services; however, existing designs still suffer from limitations such as small font sizes, low color contrast, insufficient voice guidance, and a lack of scenario-specific functions. This study reviews relevant policies and theoretical foundations, analyzes the needs of elderly users based on survey data, and develops a functional framework to address these deficiencies. It proposes physiology-informed visual strategies, habit-oriented interaction optimizations, and a closed-loop service model that integrates health monitoring with medical services to support multimodal information delivery and one-click operations. The findings expand the application of age-friendly design principles in healthcare, provide empirical support for scenario-integrated approaches, and offer practical recommendations to enhance app usability and user engagement, thereby promoting effective health management for older adults and advancing the inclusive, human-centered development of the smart elderly care ecosystem.
