Coming from iAPS

What to Expect After Install

  • Onboarding Wizard
    Trio will walk you through the initial setup of the app. Learn more in the New User Setup Guide.
  • User Interface
    You can find more about the Trio User Interface in this walk-through of the app.
  • Remote Commands & iOS Shortcuts
    Trigger actions like carb entry, bolus, overrides, or temporary targets remotely or through shortcut automation.
    • Use Loop Follow v4.0 or Later for remote commands
      More info at LoopFollowDocs
  • Bolus Calculator
    The Bolus Calculator in Trio offers simple dosing with clear breakdowns and safety logic.
  • In-App Statistics
    There are multiple statistics and graphs available in the Trio app. Click the link to learn more about the Statistics available in the app.
  • Important Re: Autotune
    Autotune has not performed well with the addition of Dynamic ISF and many users using multiple ISF and CR in Therapy settings. For this reason, we have removed it until an improved Autotune-like feature is built.
  • No Dynamic Carb Ratio
    There is no evidence to support that your carb ratio varies as ISF does with increasing or decreasing glucose levels. For this reason, Dynamic CR has not been implemented in Trio 0.5+.

What to Expect in Your First 3 Hours

Here are some things to keep in mind after moving from iAPS to Trio v0.5+ in the first 3 hours:

  • Dynamic ISF
    Dynamic ISF is disabled for the first 7 days.

    Dynamic ISF & Closed Loop

    Trio must be in Closed Loop for 7 days in order to enable Dynamic ISF.

  • Autosens
    Autosens will require 8–24 hours of data before it starts making adjustments. You may need to enter carbs and bolus during this time if you aren't already doing so.

    Initial Limitation with Autosens

    There's a long standing issue with Autosens where it will likely be stuck at 100% for the first 24 hours when there are carb entries or SMBs.

    • When carb entries or SMBs are not present, Autosens will kick in after 8 hours.
    • When carb entries or SMBs are present, Autosens will kick in after 24 hours.

    Whether or not to enable SMBs or enter carbs is a personal choice based on what you prioritize in your first 24 hours.

  • Onboarding Wizard
    Take this time to go through the Onboarding Wizard. Reference the New User Setup Guide or ask questions on Facebook or Discord if you have any questions.

  • Test Settings
    This is a great time to test your settings so you can start fresh on solid footing.
  • New User Interface
    Use this time to learn the New User Interface.

    Do not use a pump or cgm simulator

    • Doing so will result in false data being stored and you will have to delete the app with all the data and reinstall before you can use it on a live pump.
    • This will also reset your 7-day waiting period for Dynamic ISF.
    • More information on simulator use

What to Expect After 24 Hours

A full day on Trio! Congratulations! Here's what to look for:

  • Autosens
    Autosens now has enough data to make adjustments.
  • Review & Test Settings
    This is a good time to review your last 24 hours of results to see if your core settings performed as expected. If you had unexpected challenges with your settings, look at how to test them over the next 7 days:

  • Review Dynamic ISF Documentation
    Review the documentation on Using Dynamic ISF in preparation for Day 7.


What to Expect After 7 Days

You've completed a week on Trio! Here's what you should see:

  • Dynamic ISF
    Dynamic ISF now has enough data. You now have the option to enable it.

    This is a great time to refresh Using Dynamic ISFand check your settings for Logarithmic Dynamic ISF or Sigmoid Dynamic ISF.

    Can't Enable Dynamic ISF?

    If Dynamic ISF does not give you the option to enable, you may have experienced one or more of the following:

    • You were not in closed loop for the full 7 days.
      • Trio needs 7 days of closed loop to safely enable Dynamic ISF
    • You had significant loss of connection with your CGM and/or pump.
      • Check your last week of Looping Statistics in the Stats tab in the Trio app. You need both 7 days and an 85% success rate to enable Dynamic ISF.
    • You enabled a significant number of manual Temp Basals with long run times.
      • When a manual Temp Basal is set, Trio is unable to complete a loop cycle for the duration of the temp basal. This will cause a reduction in your success rate. If you do not have 85% success rate for 7 days, you cannot enable Dynamic ISF.
  • Dynamic CR
    Dynamic CR has been removed due to no known scientific validity to CR changing with an increase or decrease in glucose.


Convert iAPS Settings to Trio Settings

When you move your settings from iAPS to Trio, some of them might look different even if they have the same or similar names. That’s because we some of the numbers went from decimals to percentages to make them easier to understand.

Example

In iAPS you might set "Autosens Maximum" to 1.2. In Trio, we show "Autosens Max" as 120%, which means the same thing, but is easier to understand.

Percentage vs Decimal

Tip

  • To convert a value from a decimal to a percentage, multiply it by 100.
  • To convert from a percentage to a decimal, divide by 100.

Some setting names have also changed. We did this to make things less confusing. To help you out, we added definitions right in the app. Just tap the question mark icon next to any setting to see what it means. Healthcare Professionals and users can also find those settings and explanations in this section of the docs.

In iAPS, some settings had limits (called guardrails) that weren’t always visible, and others had no limits at all. In Trio, we’ve made those guardrails easier to see and added a few more where needed, to help prevent settings that could lead to unsafe or unexpected outcomes.

The charts below will help you see which setting names or formats have changed, and where to find them in both iAPS and Trio.
