CGM features and fixes · Dexcom G7
Does the Dexcom G7 work with Apple Watch?
What Dexcom G7’s own apps (Dexcom G7 app, Dexcom Follow) do, from the maker’s documents.
Yes
The G7 app has an Apple Watch app. With Direct to Watch, the sensor sends readings straight to the watch, so the phone can stay behind (a phone is still needed to pair each new sensor, and the watch cannot share with followers unless Direct to Watch is on and it has Wi-Fi). Dexcom Follow also runs on Apple Watch. (Dexcom; App Store listing; Dexcom user guide, p. 83)
With Glide
Yes
Glide has an Apple Watch app and two watch face complications. The watch signs in from the iPhone; the app shows the number, the change per 5 minutes, how old the reading is and the last 3 hours. (/dexcom#apple-watch)
