Trio 0.5.0 Public Beta

Tips, Tech & Gear DIY
1

As I’ve reported elsewhere, I’ve been one of the Trio closed beta testers. The developers believe it’s far enough along to allow a more broad set of DIY AID users to build, use, and test the app. It’s intended for experienced AID users, particularly Trio/iAPS 0.2.x users. A Trio Docs and community Discord link are provided. If interested, I highly encourage reading the docs BEFORE building the app so you’re familiar with all the settings, needed information, and decisions you will need to make. If you build/use the app, the experience and results will likely be decidedly different from Loop, AAPS, OAPS, iAPS and others. Some will like it, some will not, but it’s another choice currently available to you. The below is copied from the Trio Discord announcing it’s availability yesterday:

Trio v0.5.0 – Public Beta <:trio:1243256147595493447>

Soon… is NOW.

This public beta release is the culmination of thousands of hours of work by dozens of contributors since late 2023. Trio has been rebuilt from the ground up for clarity, reliability, and usability—with a new look, powerful new features, and a strong focus on user experience and safety for @everyone.

This isn’t just another app update. This is the next chapter of open source AID.

What’s New

  • Brand New Interface
    A completely redesigned UI across the app and watchOS—clean, modern, and easier to use.

  • All-New Onboarding
    Step-by-step setup for new and returning users with smart defaults and safety checks.

  • Rewritten Backend & Data Storage
    Entire app logic and data storage rewritten for speed, stability, and future flexibility.

  • Remote Commands & iOS Shortcuts
    Trigger actions like carb entry, bolus, overrides or temporary targets remotely [1] or through automation.

  • Smarter Settings
    Helpful hints, guidance sheets, and a built-in search function—just like iOS Settings. The all-new Trio Settings.

  • New Bolus Calculator
    More accurate, simple dosing with clearer breakdowns and improved safety logic.

  • Reworked Statistics
    All in-app statistics and graphs have been overhauled and extended.

  • Live Activity Widget
    Real-time loop data with optional chart—configurable and tailored to your preferences.

  • Live Data on Watch
    Highly customizable “contact widgets” for glucose, IOB, COB, and more, always visible.

  • All-New Integrations
    Nightscout, Tidepool, and Apple Health connections have been rebuilt from scratch—faster and more stable.

  • Safety Improvements
    Dynamic ISF guarding (7-day required data), safer edge-case behavior, and improved support for high-insulin-resistance setups.

  • Updated Language & Translations
    Clear, friendly, and easy-to-understand. Fully localized with ongoing help from our Crowdin contributors (translators still welcome).

[1] requires Loop Follow v2.4.0

Important Notes for Public Beta Testers

  • All users must complete the Onboarding Wizard after upgrading.
  • If migrating from a previous 0.2.x build, 24 hr treatment data and therapy settings will be preserved.
  • Your pump and CGM connections will be brought over automatically.
  • Algorithm settings, dynamic ISF and some integrations (like Nightscout) will reset.

This public beta is intended for experienced users and long-time Trio 0.2.x users, not beginners.
→ Visit TrioDocs for instructions and help on how to update and build.
→ Feedback is welcome via GitHub Issues or the community Discord

A Note on Compatibility
Upgrading to Trio v0.5.0 from 0.2.x is smooth and straightforward. The new Onboarding Wizard will guide you step by step.

Be Aware:

  • Once you have upgraded to v0.5.0, going back to 0.2.x is not supported.
  • If you choose to downgrade, you will need to set everything up again from scratch.

We have designed this release to be a stable and long-term foundation—so when you are ready, you can upgrade with confidence.
