Trio - an automated insulin delivery system for iOS based on the OpenAPS algorithm with adaptations for Trio.
The project started as Ivan Valkou's FreeAPS X implementation of the OpenAPS algorithm for iPhone, and was later forked and rebranded as iAPS. The project has since seen substantial contributions from many developers, leading to a range of new features and enhancements.
Following the release of iAPS version 3.0.0, due to differing views on development, open source, and peer review, there was a significant shift in the project's direction. This led to the separation from the Artificial-Pancreas/iAPS repository, and the birth of Trio as a distinct entity. This transition marks a new phase for the project, symbolizing both its evolution and the dynamic nature of collaborative development.
Trio continues to leverage a variety of frameworks from the DIY looping community and remains at the forefront of DIY diabetes management solutions, constantly evolving with valuable contributions from its community.
You can either use the Build Script or you can run each command manually.
If you copy, paste, and run the following script in Terminal, it will guide you through downloading and installing Trio. More information about the script can be found here.
/bin/bash -c "$(curl -fsSL \
https://raw.githubusercontent.com/loopandlearn/lnl-scripts/main/TrioBuildSelectScript.sh)"
In Terminal, cd to the folder where you want your download to reside, change <branch> in the command below to the branch you want to download (ie. dev), and press return.
git clone --branch=<branch> --recurse-submodules https://github.com/nightscout/Trio.git && cd Trio
Create a ConfigOverride.xcconfig file that contains your Apple Developer ID (something like 123A4BCDE5). This will automate signing of the build targets in Xcode:
Copy the command below, and replace xxxxxxxxxx by your Apple Developer ID before running the command in Terminal.
echo 'DEVELOPER_TEAM = xxxxxxxxxx' > ConfigOverride.xcconfig
Then launch Xcode and build the Trio app:
xed .

If you would like to give something back to the Trio community, there are several ways to contribute:
When you have successfully built Trio and managed to get it working well for your diabetes management, it's time to pay it forward. You can start by responding to questions in the Facebook or Discord support groups, helping others make the best out of Trio.
Trio is translated into several languages to make sure it's easy to understand and use all over the world. Translation is done using Crowdin, and does not require any programming skills. If your preferred language is missing or you'd like to improve the translation, please sign up as a translator on Crowdin.
Do you speak JS or Swift? Do you have UI/UX skills? Do you know how to optimize API calls or improve data storage? Do you have experience with testing and release management? Trio is a collaborative project. We always welcome fellow enthusiasts who can contribute with new code, UI/UX improvements, code reviews, testing and release management. If you want to contribute to the development of Trio, please reach out on Discord or Facebook.
