Tidepool

Tidepool is a nonprofit organization committed to providing diabetes data software that is always free, always available, always on, and always easy to use. Our software is designed to connect devices, data, and people — whether you're a person with diabetes, caregiver, healthcare provider, or researcher. 

Tidepool Loop is an automated insulin delivery system for your iPhone and Apple Watch, currently in development. It is intended to work with commercially available insulin pumps and CGMs (continuous glucose monitors).
