Look at your CGM data everywhere you Like to Look. GotCGM takes the continuous glucose monitor (CGM) data from Dexcom or Libre blood sugar sensors and routes it in real-time to the places you actually look - your Apple watch, Apple Health, the iPhone lock and home screens, the dynamic island while you're in other apps, and your car - so you can glance at your blood sugar and get on with your day. WHY PEOPLE USE IT * Apple Watch: See your current BG and trend at a glance. GotCGM uses a custom Contact Complication to share CGM data to your watch in real time. * Apple Health: Puts the data from your CGM into AHK so you can see trends against your other health data, share with clinics and your physician, and more. * iPhone at a glance: Lock-screen and home-screen widgets keep BG visible without opening the app. * Live Activities show in the Dynamic Island and on your iPhone lock screen, on your Apple Watch, and with CarPlay. * For other watches and also in the car: the Calendar Integration surfaces BG info as a calendar event * Simple setup: Use your Dexcom Share or LibreLinkUp credentials to start routing your CGM data immediately and in real time. SUPPORTED CGMs * Dexcom G6/G7 * Abbott Freestyle Libre 2/3(+) * Other CGMs that have been configured to write their data into Apple Health or can write into Nightscout.
