i wish is had my history like the libre 3 app.
Not able to use the app without allowing it to override do not disturb settings.
First time setup as the adult with a minor is awful
it has totally messed my phone up and completely takes 54 % of my battery ,always having to charge my phone . horrible
What goes well
It’s helped me so significantly to control my spikes like nothing ever has.
excellent product, highly recommended!
No complaints here, the product works great for me and the app has come a long way since the early days.
Dexcom G7 is so easy to use, both parts of it. I love it and would recommend it to all type 2 diabetics.
I really appreciate them reaching out the way they did!!

After upgrading my phone I can no longer access the app
Constantly glitching out, disconnecting for hours at a time, failing sensors, the display will corrupt itself and I have to restart to fix it.

The new TOCs require way more data than I'm comfortable giving to Dexcom.

I need this app. It's helpful to see my glucose and put like insulin events and like food events and but that's it. Otherwise it's horrible. It crashes all the time. It has horrible stability issues.
