The Philosophy of the “Glance”
GlucoGlance is built on one simple idea:
you should understand your status in under one second.
Most diabetes apps focus on a single number. Over time, this leads to fatigue, constant checking, and over-interpretation. GlucoGlance takes a different approach—one centered on Time in Range (TIR) and immediate visual context.
Modern diabetes management isn’t about chasing a perfect number. Clinical guidance consistently shows that staying within range most of the time is what matters. GlucoGlance is designed to make that range—not the number—the first thing you see.
This is the philosophy of the Glance:
minimal time, maximum clarity, zero interpretation burden.
A Passive Extension — Not a Medical Device
GlucoGlance is not a medical device and does not replace FDA-approved systems.
It is a Secondary Data Extension, designed to work alongside your existing CGMs and pumps.
GlucoGlance does not:
- Control hardware or deliver therapy
- Provide dosing instructions
- Modify or override medical data
The “Passive Mirror” Architecture
GlucoGlance operates under a strict read-only philosophy:
Notification Mirroring
System alerts from approved apps are captured and visualized without alteration.
Cloud Polling
Historical data is retrieved from official cloud providers to build a unified, high-fidelity view.
Arithmetic Verification
Optional math utilities allow users to validate insulin-to-carb and correction logic already used by their primary systems.
The CRTI — Logic in Motion
At the core of GlucoGlance is the CRTI (Colorized Rotating Trend Icon).
CRTI combines three concepts into a single visual:
- Color Logic – Reflects user-defined thresholds (Target, High, Low, Urgent)
- Rotational Logic – Represents rate of change over time
- Continuity – Appears consistently across status bar, notifications, Home UI, and Wear OS
CRTI lets your brain understand range and momentum instantly—without reading numbers.
GlucoGlance Highlights
Multi-User & Multi-Sensor Support
- Roles: Primary and Follow
- Compatibility: Eversense 365, Dexcom G7, FreeStyle Libre 3, Dexcom Follow, LibreLinkUp, AAPS, GlucoDataHandler, Gluroo, Juggluco, xDrip
Logging & Fullscreen Graph Activity (FGA)
Three Dedicated Logs
Separate historical records for Glucose, Insulin, and Bolus activity.
Source of Truth Enforcement
Only the sensor marked Primary at the time of reading is committed to the permanent glucose log, ensuring data integrity.
Fullscreen Graph Activity
Long-range graphing with insulin overlays, allowing review of any collected sensor data without altering original records.
Intelligent Notifications
Combo Notifications
Unified alerts combining glucose (CRTI) and IOB in a single view.
Math-Check Alerts
Correction and nutrition alerts that support arithmetic verification—not dosing decisions.
Wear OS Extension
GlucoGlance brings the full Passive Mirror experience to your wrist.
Weighted Elements
Complications that visually prioritize in-range (green) status through customizable thresholds and colors.
Future-Ready
Upcoming insulin decay visualization based on user-defined action duration.
Dynamic On-Tap Complications
These are not static labels—they are state-driven data engines.
Live Glucose Status (CRTI)
Cycles through glucose value, delta, elapsed time, and TIR summaries for 1h, 3h, and 24h, all without opening an app.
Live Insulin Status
Tracks IOB, last bolus, and automatically surfaces correction states when detected—acting as a proactive safety signal.
Visual Decay Ramps
Custom ramp iconography provides immediate analog context for TIR and insulin decay, eliminating guesswork.
Tap-to-Cycle Logic
Each complication instance is independent, allowing one to show raw data and another to show TIR—fully customizable per watch face.
Your Data, Everywhere
- Always Visible: Status bar, Home UI, notifications, complications
- The Big Picture: Live Wallpaper and Desktop Clock turn your device into a dedicated display
- Eyes on the Road: Optional spoken glucose and IOB for hands-free awareness
A New Way to See — Not Decide
GlucoGlance exists to answer one question instantly:
“Am I in range, and which way am I moving?”
Nothing more. Nothing less.
