Yes, the app will still work even with Control-IQ turned off! You’ll still be able to see your CGM trendline and bolus from the app, as usual.
Control IQ has a few settings you can’t change:
- Target BG will be set to 110. (ETA: My diabetes educator says the ability to customize this is in the works, hopefully sometime in 2026!)
- Insulin Duration will be set to 5 hours.
- Control-IQ turns on an auto-bolus feature which can deliver a bolus if your BG is rising and you haven’t taken any insulin in an hour, unlike Basal-IQ which just increases basal for highs. However, the Sleep mode of CIQ turns off the auto-bolus feature so it only makes basal adjustments!
There are some settings you can adjust though:
- Weight and Total Daily Insulin. I think the algorithm probably uses this to help determine how insulin resistant you might be. (Set this under Options / Control IQ.)
- Basal limit. If you don’t want CIQ to be able to double, triple, quadruple your basal to bring down BG, you’d set this at the max basal you are comfortable with. (Set this under Options / Personal Profiles / Pump Settings.)
I’ve liked CIQ in general! I don’t know if you were also eligible for the recent X2 extended bolus update – I can never remember which updates are prerequisites – but being able to set an extended bolus up to 8 hours has been awesome.
