Setup walkthroughs, compatibility, and straight answers about getting your glucose onto a Garmin watch. Written from what actually happens in production, not from a brochure.
GGlance is the quickest route from a FreeStyle Libre or Dexcom sensor to your Garmin watch: one free app, both sensor brands, nothing to host and no account to create.
Connect a Dexcom G6 to your Garmin watch with GGlance, through Dexcom Share. Setup takes a few minutes and needs no extra hardware.
Connect a Dexcom G7 to your Garmin watch with GGlance. The path is Dexcom Share, and the setup is the same as for the G6.
Dexcom ONE and ONE+ do not offer Dexcom Share, which is the only route a third-party app has to your readings. Here is what that means.
Share has to be on, sharing with someone, and you must use the sensor wearer's login. Here is why each of those matters, and what goes wrong when one is missing.
Step by step: connect a FreeStyle Libre 2 sensor to your Garmin watch through LibreLinkUp and GGlance, in about five minutes.
Connect a FreeStyle Libre 3 sensor to your Garmin watch with GGlance. The route runs through LibreLinkUp, and setup takes about five minutes.
The full compatibility list: supported Garmin models, FreeStyle Libre and Dexcom sensors that work, and the ones that cannot.
A stale or missing reading almost always comes from somewhere earlier in the chain than the watch. Here is the order to check things in.
The full path a reading takes from sensor to wrist, what the GGlance relay does, and what is and is not kept.
Why GGlance asks for a LibreLinkUp follower login rather than your Abbott account, and how to create one in a few minutes.
Why a wrist reading is a few minutes behind your phone, how often GGlance refreshes, and the real battery impact.
