1. Discover - Competetive Analysis
Dexcom is a leading continuous glucose monitoring app that provides real-time glucose data, trend analysis, and alerts. It was chosen as a competitor due to its strong presence in the market and comprehensive feature set, serving as a useful reference for understanding best practices and potential usability gaps in glucose tracking experiences.
Trend arrows and graphs aren’t always intuitive.
Accessibility (font size, color contrast) can be a barrier.
‘My biggest problem with Dexcom? No dark mode. My eyes aren't what they used to be, and dark text on white background is hard to read.’ - User's voice - Reddit – r/dexcom (source)
Data density can feel overwhelming
‘…I just got on Dexcom G6 and while I know it will be a huge asset to me, right now it’s just utterly overwhelming trying to start from square one and gain control’ - User's voice - Reddit (source)
2. Define
Goal
Create a next-generation Continuous Glucose Monitor (CGM) experience.
Audience
Initially designed for people with Type 1 diabetes, the product aims to eventually engage a wider audience of wellness users interested in metabolic health.
Current Gap
Existing CGM apps provide medical accuracy but lack visual clarity and actionable insights.
Opportunity
Design a simplified, visually clear, and insight-driven CGM experience that helps users.
4. Deliver
Homescreen
The homescreen highlights the user’s current glucose level with clear colour coding (green for safe, yellow for borderline, and red for critical). Severe readings stand out in bold red for quick recognition.
A dynamic trend graph mirrors these colours with smooth gradient transitions, helping users intuitively interpret their data.
Through pinch-to-zoom interactions, users can explore glucose trends in detail, revealing precise timestamps and values for deeper insight.

When users scroll up, the glucose value subtly shrinks to keep focus on detailed insights, while the time picker stays fixed for easy navigation.
The summary section is customisable, letting users choose and reorder the metrics that matter most. AI-driven insights like “Glucose has been stable for 2 hours” add quick, personal context to daily trends.
Alerts
Global Alerts
These alerts surfaces essential system messages like signal loss or brief sensor issues, keeping users informed.
Specific Alerts
Glucose Alerts, from mild changes to critical highs or lows, helping users act quickly and confidently.
