GGlance - CGM DataField Libre Dexcom

GGlance shows your FreeStyle Libre or Dexcom CGM glucose on your data screen while you train - big value, trend arrow, and a color-coded history graph - so you can watch your blood sugar on a run or ride without reaching for your phone. Works with FreeStyle Libre 2 and 3 (LibreLinkUp) and Dexcom G6/G7 (Dexcom Share). Free, no ads.

Follow the step-by-step guide at https://gglance.app/en/tutorials 2. Add GGlance as a Connect IQ data field to an activity screen 3. Enter your CGM login in THIS field's settings - data fields have their own, separate from the GGlance app ━━━━━━━━━━━━ FEATURES • Big value with trend arrow, color-coded by range • History graph, 1-12 hours, with high/low guide lines and a live "now" dot - or off for a bigger number • Saves glucose into the activity - the curve appears on your Garmin Connect chart, with avg, min and max • Low alert - vibrates and turns red when a FRESH reading drops below your low threshold (can be turned off) • Color zones - white in range, yellow/orange high, red low • Reading age shown, and the value greys when stale • Units in mg/dL or mmol/L, recorded in the same units • Your own high/low targets, update interval (1-5 min), 24h or AM/PM • Any activity, 100+ watches: Forerunner, Fenix, Epix, Venu, Edge ━━━━━━━━━━━━ REQUIREMENTS Your phone nearby with internet during the activity. 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 following your sensor - enter ITS email and password, not your 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 too). Dexcom ONE and ONE+ are NOT supported - no Dexcom Share, so no app can read them • Dexcom Share 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 • Use the login of the PERSON WEARING THE SENSOR - the account that publishes readings. Opposite of Libre: a Dexcom follower login signs in but shows no data ━━━━━━━━━━━━ PRIVACY No 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 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. It is NOT a medical device and is NOT intended for diagnosis, treatment decisions, insulin dosing, or any therapeutic purpose. It does not replace your Libre or Dexcom system, a glucose meter, or professional medical advice. Values may be delayed, inaccurate, or unavailable. The low-glucose vibration alert is a convenience only - it can be delayed or missed (out of phone range, alert off, stale reading, or the field not on your active screen) and must NOT be relied on as a medical alarm. Always confirm critical values with your official LibreLink or Dexcom app, your sensor, or a meter, and follow your healthcare provider's guidance. Availability depends on your CGM service, your phone and watch internet, and GGlance status. ━━━━━━━━━━━━ GGlance is an independent app, not affiliated with, endorsed by, or supported by Abbott, Dexcom or Garmin.
