GGlance - CGM App Libre Dexcom

GGlance shows your FreeStyle Libre or Dexcom CGM glucose on your watch - a glance card and a full 12-hour graph - so you can check your blood sugar without reaching for your phone. Works with FreeStyle Libre 2 and 3 (LibreLinkUp) and Dexcom G6 and G7 (Dexcom Share). Free, no account, no ads.

Link: https://apps.garmin.com/apps/7c75ab12-67c8-47ad-8fb9-e6253576c752 ━━━━━━━━━━━━ SETUP Follow the step-by-step guide at https://gglance.app/en/tutorials ━━━━━━━━━━━━ FEATURES • Glance card - current glucose, trend arrow, and a mini history line, color-coded by range • 12-hour graph - large value with trend, a color-coded curve, your high/low guide lines, and the period's high & low • Adjustable graph range - 1 to 12 hours • Color zones - white in range, yellow/orange when high, red when low • Fresh on every look - opening the glance or app fetches a new reading, shows its age, and greys it when stale, so you never read a stale number unknowingly • On-demand refresh - press START • Choose your units - mg/dL or mmol/L • Set your own high and low targets, plus 24-hour or AM/PM time • Automatic region detection • 90+ Garmin watches: Forerunner, Fenix, Epix, Venu, Vivoactive, Instinct 3, Enduro, Edge ━━━━━━━━━━━━ REQUIREMENTS Your phone nearby with internet, so the watch can fetch data. Pick your CGM source in the settings, then enter that account's login. IF YOU USE FREESTYLE LIBRE • A Libre 2 or 3 sensor with the LibreLink app on your phone • A LibreLinkUp (https://www.librelinkup.com) "follower" account that follows your sensor - enter ITS email and password, not your main Abbott/LibreLink login • Accept any pending terms in the LibreLinkUp app first, or sign-in is refused IF YOU USE DEXCOM • A Dexcom G6 or G7 (G4/G5 also work). Dexcom ONE and ONE+ are NOT supported - they have no Dexcom Share, so no app can read them • Dexcom Share switched ON with at least one follower (Dexcom app, Settings then Share). With no follower Dexcom uploads nothing, so there is nothing to read - you can follow yourself from a second phone using Dexcom Follow • Enter the login of the PERSON WEARING THE SENSOR - the account that publishes the readings. This is the opposite of Libre: a Dexcom follower login signs in but shows no data ━━━━━━━━━━━━ PRIVACY No GGlance account, no tracking, and your glucose history is never stored on a server. • FreeStyle Libre: your password never leaves your phone - the watch signs in directly with Abbott • Dexcom: sign-in goes through the GGlance relay, as Garmin watches cannot read Dexcom's replies directly. Credentials are sent encrypted, forwarded only to Dexcom, never stored or logged ━━━━━━━━━━━━ IMPORTANT DISCLAIMER GGlance is for informational and convenience purposes only.
