Designing the Continuous Glucose Monitor Experience: An App Design Process Overview

Users of continuous glucose monitors (CGMs) experience the product in part through software. Smartphone and watch apps empower people affected by diabetes to make real-time treatment decisions based on glucose readings and aggregate data such as medication, nutrition, and activity information. As CGMs evolve and gain greater market adoption, there's opportunity for these apps to play a greater role in users' lives and diabetes management. To do so, designers should follow the best practices established by the broader technology community and apply them to the needs of this community. The process of thorough discovery research, clear problem definition, iterative design, and testing can lower barriers toward broader adoption, and favorably influence the health of users through their mobile apps.
