If you've ever explored the world of automated insulin delivery (AID) systems, you’ve probably heard about DIY Loop. After three years of using it, I can confidently say it’s been a game-changer for managing my type 1 diabetes thanks to its advanced controls and customization. However, it has its weaknesses too. Today, I’ll share what I love about DIY Loop, how I use it, and areas where I’d like to see improvement. DIY Loop is not an FDA-approved system—read our safety disclaimer.
Back to the basics – What is DIY Loop?
Loop is an experimental, open-source automated insulin delivery (AID) system stemmed from the #WeAreNotWaiting movement. Unlike FDA-approved systems like Omnipod 5, Tandem’s Control-IQ, or Medtronic’s offerings, DIY Loop relies on users to build the app themselves—you can’t download this on any app store. It connects your continuous glucose monitor (CGM) and your insulin pump via an iPhone app to regulate insulin delivery (most commonly, an Omnipod DASH pump and a Dexcom CGM). While it’s not FDA-approved, it has features that set it apart, including Apple Watch control, customizable target ranges, and experimental algorithms, making it a preferred choice for those seeking greater personalization and tighter control for their diabetes management.
