- Increased accuracy of symptom reporting, improving clinical decision-making
- Streamlined onboarding for better accessibility and reduced drop-off
- Delivered a scalable, clinician-validated design under rapid-response conditions
🎯 Objectives
- Redesign the onboarding and symptom-reporting experience for Sibel’s ANNE mobile app
- Improve accuracy and completion rates of symptom data submissions
- Leverage over 100,000 hours of real patient data to identify UX gaps
- Support vulnerable populations by designing for accessibility and trust
- Launch a validated solution quickly during the pandemic response window
🧠 Background
Sibel Health’s wireless biosensors were being used in hospitals and homes to capture real-time health data during the COVID-19 crisis. While technically powerful, the mobile interface faced usability challenges—patients found it difficult to navigate the app and report symptoms consistently, especially under stress or with limited digital literacy.
To increase the impact of our remote monitoring platform, we needed a patient-centered redesign that encouraged participation and improved data quality.
🔍 Research & Strategy
I led the UX strategy using quantitative data from over 100,000 hours of sensor use to identify patterns of drop-off and friction. This was complemented by:
- User interviews with patients and caregivers to understand mental models and trust barriers
- Feedback from clinicians on what symptom data was most clinically relevant
- Mapping of both patient and clinician journeys to identify high-impact opportunities
The research revealed that confusing onboarding flows and unclear feedback mechanisms were major drivers of disengagement.
🛠 Design Process
I focused on simplifying and optimizing the experience across four key areas:
- Onboarding: Streamlined setup to reduce friction and anxiety, especially for first-time users
- Navigation: Designed clear, progressive pathways for symptom input and history review
- Feedback: Integrated real-time visual confirmations to validate successful entries
- Accessibility: Applied inclusive design principles (e.g. larger tap targets, readable contrast, plain language) to support diverse patient populations
Each iteration was validated with real users and clinical stakeholders in weekly feedback loops.
🤝 Cross-functional Collaboration
Throughout the project, I worked hand-in-hand with:
- Product managers, to align roadmap and prioritize clinical needs
- Engineers, to ensure design feasibility and minimize tech debt
- Clinical teams, to validate the medical accuracy and interpretability of outputs
I also supported QA and post-launch adjustments to ensure consistent implementation across devices.
🧭 Reflection
This project proved the power of combining sensor data with thoughtful UX research. It also highlighted the importance of clarity and accessibility in high-stakes health contexts—especially during a crisis.
Designing for vulnerable users in a fast-moving environment taught me how essential it is to focus on trust, simplicity, and collaboration when building tools that impact real lives.
