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
