🙏 Much Gratitude

How do you thank an App for literally saving your life multiple times? Immense value (bonus while
traveling solo!)!
Sugarmate calls to check in and to tell me when my glucose is low. Who does that for you? Consistently? What
if it was an off day? This is THE backup plan for those days and then some.

Nice but needs work

Nice comprehensive app but needs to integrate with the pump to tie in insulin and boluses etc.

CGM Data Only?

What’s the point of being able to connect to Tandem Source if the app doesn’t automatically pull in insulin basal/bolus/correction information?
Another shortsighted release by Tandem. Better question, why am I still surprised by their choices?
I don’t want a nickname. UGHI don’t want a nickname. UGH

Sugarmate is Awesome!

I love how there is a feature that can call your phone when having a low blood sugar! Love this app!
