Does GotCGM™ replace the CGM app on my phone?
No, GotCGM™ does not connect to or control your CGM in any way. We just pull the data from the cloud services (Dexcom Share or LibreLinkUp). You still need the primary CGM app to start your sensors and view your CGM readings.
How often does my watch update with new glucose readings?
Apple Watch complications can receive up to 60 real-time updates per hour when new glucose readings are available from your CGM.
Wear OS tiles and complications update whenever new data arrives from Dexcom or Libre.
Can I see my glucose on my iPhone Lock Screen or Dynamic Island?
Yes! GotCGM™ supports iOS Lock Screen widgets, Live Activities, and Dynamic Island (on iPhone 15 and newer). You can see your current glucose, trend arrow, and time since last reading right on your lock screen.
Does GotCGM work with Android widgets?
Yes, GotCGM™ provides Android home screen widgets that display your glucose readings. You can also see your data in Android Auto via calendar events.
