Loop for iOS

Loop is an app template for building an automated insulin delivery system. It is a stone resting on the boulders of work done by many others.

Loop is built on top of LoopKit. LoopKit is a set of frameworks that provide data storage, retrieval, and calculation, as well as boilerplate view controllers used in Loop.

Please understand that this project:

Is highly experimental
Is not approved for therapy

Documentation

Please visit the Loop Docs for installation, algorithm, and other details.
