Abstract
Diabetes management presents unique usability challenges for older adults, particularly in adopting digital health tools. This study evaluates the usability of the GlucoCheck Companion App, which interfaces with a non-invasive glucose monitoring device using AI-driven near-infrared technology. Twelve older adults (aged 65+) participated in a usability test involving core app tasks such as real-time glucose viewing, historical data tracking, and food logging. Findings suggest that GlucoCheck offers a user-friendly, accessible solution for older adults managing diabetes, but continued refinement is essential to address age-related accessibility needs. The study contributes to advancing human-centered design for mobile health tools supporting chronic disease management in aging populations.
