WHAT IS TRIO?

Trio is 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 later forked and rebranded as iAPS. Since then, many
developers have contributed substantial work, leading to a range of new features
and enhancements.

Following the release of version 3.0.0, the project’s direction significantly
changed due to differing views on development, open source, and peer review.
This led to the separation from the Artificial-Pancreas/iAPS repository and the
birth of Trio as a distinct entity. This transition marks the project’s new
phase, symbolizing its evolution and the collaborative development’s dynamic
nature.

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.

Before starting with Trio, you should evaluate all your closed-loop options,
including:

 * Commercial systems such as Medtronic’s 780G, Tandem’s Control-IQ, or
   Insulet’s Omnipod 5

 * Other open-source applications like Loop and AndroidAPS

Warning

Trio is a DIY, open-source community project. It has not been evaluated by any
regulatory agency and is for use at your own risk.


GETTING STARTED

Before starting with Trio, you should understand carb ratio (CR), insulin
sensitivity factor (ISF), and basal rates. If you have read the documentation
and still require help identifying your settings, please seek advice from your
healthcare provider.

To use Trio, you are required to build the application from the source code.
This does not require substantial technical know-how but is a time-consuming
process. You may need several sessions to complete your first build.

Upon installation, you will need to configure your settings appropriately. By
default Trio acts no differently than your pump, with the exception that it may
recommend temporary basals from time to time. The magic happens by turning on
“Closed Loop”, enabling Super Micro Bolus (SMB) features, and turning on dynamic
features.

> In general, these are the first three settings you will want to configure as
> you gain confidence in the app and your settings:
> 
>  * Enable Closed Loop for automation
> 
>  * Increase Max IOB to “average meal bolus + 3x max daily basal”
> 
>  * Enable SMB and UAM for automatic bolusing (ensure your ISF is optimized
>    before enabling this) See Configure for more information on Trio
>    configuration.

If you are considering a transition from another closed loop system, please read
this section first.


CONTRIBUTION

Trio is built by a volunteer community. If you are interested in helping as a
programmer, you can contribute to the Trio or OpenAPS code base. Trio is mostly
written in SwiftUI, and the OpenAPS algorithm is written in JS.

You can also provide support in online support groups by helping users adjust
their settings and troubleshoot common errors.
