Bionic Circle is an educational and reference application designed for iPhone users to facilitate diabetes management for individuals using the iLet system. This app allows users to invite up to ten people to join their Circle, enabling loved ones to monitor essential diabetes data remotely. Key features include real-time access to continuous glucose monitoring (CGM) values, meal announcements, insulin doses, and alerts for various glucose levels.

The app provides a secure wireless connection, ensuring that caregivers can follow the user's glucose levels and insulin management throughout the day and night, regardless of their location. Users can rely on the Bionic Circle to maintain awareness of their loved one's diabetes management, whether they are at school, work, or traveling. However, it is important to note that dosing decisions should be made based on the iLet Bionic Pancreas System and under the guidance of a healthcare professional.
