One Touch Reveal Mobile App designed to help users better manage their diabetes while making the experience intuitive, supportive, and empowering.
Enhancing the User Experience for Diabetes Management
Overview
One Touch Reveal is a mobile health app designed to help people with diabetes track, visualize, and manage their blood glucose levels. When I joined the team, the app had strong functionality but lacked clarity, consistency, and personalization. My goal was to transform the experience into something more intuitive, emotionally supportive, and easy to navigate for users managing complex health routines.
the challenge
The existing app faced multiple UX issues:
Inconsistent design language across screens
Fragmented navigation that caused confusion
Poor prioritization of critical features like glucose monitoring
Limited personalization for different user needs (e.g., caregivers vs. patients)
Our task was to redesign the experience to be clear, accessible, and empathetic — especially for users with chronic conditions and varying levels of health literacy.
Project Goals
Simplify the app experience across touchpoints and age groups
Prioritize essential tasks like glucose tracking, data visualization, and historical trends
Personalize the experience through dynamic dashboards and insights
Enhance engagement by enabling users to reflect, learn, and take action
Improve accessibility across design, language, and visual hierarchy
My Role
As the Senior Product Designer, I led UX strategy and interface redesign for the mobile platform:
Led the UX redesign of the app’s primary task flows, dashboards, and feature prioritization
Facilitated cross-functional collaboration with PMs, developers, researchers, and healthcare SMEs
Conducted usability testing with real users living with diabetes
Designed and prototyped a personalized health dashboard
Ensured the solution met compliance and accessibility standards
Discovery & Research
We began with stakeholder interviews, user reviews, and existing analytics. Insights included:
Users didn’t know where to start in the app
Glucose history was buried too deep in the flow
Users wanted a single, centralized view of their health metrics
Many expressed emotional stress and fatigue when using overly clinical interfaces
We mapped user journeys for different personas:
A middle-aged user self-managing their health
A caregiver tracking metrics for a loved one
A newly diagnosed patient learning daily routines
Design Process & key solutions
The enhanced OneTouch Reveal app delivered a more intuitive and supportive experience for diabetes management. With a redesigned interface, improved data accessibility, and customizable features, users found it easier to engage with the app and stay consistent with their health goals. The patient-focused improvements have made a significant impact, empowering users to take greater control of their diabetes management journey.
1. Redesigned Dashboard (User-Centric)
We created a modular dashboard as the home screen, emphasizing quick access to glucose readings, trends, medications, and appointments. Each module used icons, colors, and charts to reduce cognitive load and help users instantly understand their status.
2. Blood Glucose Monitoring Enhancements
We simplified how data was entered and visualized. Patients could now:
View 7/30/90-day glucose trends
Tag readings (e.g., fasting, post-meal)
Receive alerts or feedback based on anomalies
Access goal ranges recommended by their care team
3. Data Logging & Personalization
Users could now log meals, moods, exercise, medications, and set reminders. Over time, this created a personal health timeline that improved patient-provider conversations and daily decision-making.
4. Accessibility and Language
Text size, contrast, and icon labels were adjusted for visually impaired users. We also refined microcopy to be more encouraging and conversational, reducing medical jargon.
This project underscored the importance of empathetic design, demonstrating how an optimized UX can be a powerful ally for users navigating complex health challenges.
Testing & Iteration
We ran moderated usability tests with 8 participants across age groups:
100% could complete core flows faster than in the legacy version
Participants reported reduced cognitive fatigue and easier navigation
Reengagement rates increased in internal metrics (exact numbers confidential)
Feedback loops were maintained through design QA, sprint reviews, and post-launch NPS surveys.
Outcomes & Impact
3x faster onboarding and feature discovery
Improved user retention in the first 30 days post-update
Stakeholder alignment on the updated design system
A stronger patient-caregiver feedback loop
The project demonstrated how thoughtful UX in healthcare can reduce anxiety, increase health literacy, and foster confidence in daily health management.
Tools & Deliverables
Wireframes, journey maps, and personas
High-fidelity UI screens in Figma
Interactive prototypes for stakeholder demos
Design documentation for dev handoff
