r/ClosedLoopDiabetes↗

For the discussion of closed-loop diabetes management systems (first known as the "Artificial Pancreas.") We cover everything from open-source DIY solutions (e.g., Loop, AndroidAPS) to commercial Automatic Insulin Delivery (AID) systems (e.g., Control-IQ, SmartGuard). People with diabetes, caregivers, healthcare providers, and developers can join and share experiences, troubleshoot issues, and discuss the future of diabetes tech! (Educational discussions only, of course, not medical advice!)
