eREACH CM is a research-based mobile application designed to enhance chronic disease self-management and strengthen linkage to care among older adults in the community. The app enables users to record and monitor their health metrics, identify barriers to care, and request assistance from community health workers (CHWs) and trusted family and friends (TFFs). It also delivers personalized educational materials focused on hypertension, diabetes, and memory health. In addition, eREACH CM also supports education, appointment scheduling, and reminder functions to promote sustained engagement in self-care and participation in ongoing research initiatives.
