Some insulin pumps now connect to continuous glucose monitors (CGMs) to create a full-loop system. This means some t1ds can stop using their phone for the first time in over ten years. It is very liberating.
But only if you're adult. Hopefully there's a treatment :)
In the US or EU, there are many CGM and Insulin pump options for children aged 4+.
The phone is needed for caregivers to get the numbers. The CGM direct to Pump connection is all closed down as well, so features like remote Bolus don't exist in those systems.
