Welcome to the LoopDocs website where you can learn about the Loop app.

What is the Loop App?

The Loop app is an automated insulin delivery application that you build and operate on an iPhone.

• The Loop app uses your settings, meal entries and glucose data to calculate insulin dosing needed to bring your blood glucose within the correction range you set
  • You enter your personal therapy settings (e.g., basal rate schedule, carbohydrate ratio, insulin sensitivity)
  • You indicate your CGM and pump
• You choose how to operate the Loop app:
  • Closed Loop: Predict, recommend and control insulin dosing
  • Open Loop: Explore interface, test settings, learn to enter meals and dose

What are my next steps?

This site shows you step-by-step how to build, set up and operate the Loop app.

• You do not need a technical or computer background to do this
• You can choose to build the Loop app several ways:
  • Use a browser on any computer or tablet and install it on your iPhone via TestFlight
  • Use an up-to-date Mac Computer and install it directly on your iPhone

In order to become proficient with the app, you should learn the information on this site. Consider doing this over a period of time and reviewing the materials more than once.

• You should test and perhaps adjust your settings to be successful with the Loop app (or any hybrid closed-loop system)
• As you read the documentation, you will find links to a robust volunteer support community
  • You're invited - come introduce yourself
  • Don't be afraid to ask questions, just let us know where in the documentation you got confused so we can make improvements

There is a common saying in our community:

Do It Yourself (DIY) does not mean Do It Alone!

Once you are using the app, you should regularly follow one or more support forums for important updates on the Loop app. Spending this time is important for success in building and operating the Loop app safely.

This website is updated regularly to keep pace with development of the Loop app and Apple releases.

Important Disclaimer

Please consult with your health care professional regarding your diabetes management.

• The Loop app is an open source project used by many, but it is not approved for therapy by any government organization.
• You take full responsibility for building and running this system and do so at your own risk.

Volunteer Community

The Loop app has been, and continues to be, developed and supported by volunteers. From the code to this website, you are able to use this app because many volunteers continue to give their personal and family time.

Please add your time by reading this website before embarking on your Loop journey.
