What does HackerNews think of Loop?
An automated insulin delivery app template for iOS, built on LoopKit
I've turned off all other features/notifications on my Apple Watch, it just does this, and it's the most valuable product I use (since I no longer have to pull out an insulin pump in a meeting, look at some other screen to see glucose values, etc etc etc).
The app tries to predict blood glucose in the future (drawing on CGM, food intake, lots of parameters and other data) and based on that either automatically injects insulin, or asks the user to confirm.
People need to compile the app themselves because the liability in the case of adverse effects is insanely high.
It’s a highly driven community. I’ve seldom seen such a useful and well supported application of modern tech.

The guys that built Loop and the Riley Link (https://getrileylink.org/) (bluetooth to RF adapter relay to control wireless pumps that were reverse-engineered) are heroes.
