Evolving Health Tracker


At Navigating Cancer, our web-based mobile-first Remote Patient Monitoring product had usability issues and poor accessibility. The visual design was inconsistent and outdated. The content was text-heavy and lacked a conversational voice. In addition, we needed to better support updated standards for symptom grading provided by the National Cancer Institute.


We had to design and integrate a new visual design and content strategy, to improve usability, accessibility, and alignment to symptom grading standards.


We have heard from patients that Health Tracker is easy-to-use and that it helps patients feel more connected to their caregivers. The conversion rate for first-time check-in is ~60%, compared to ~20% for the legacy product. The design for standardized symptom-grading has supported data precision, and is allowing us to scale the product for clinical studies.

My Role

I ​researched and investigated opportunities for improved accessibility and usability. Designed content strategy, and visual system to support National Cancer Institute symptom-grading standards. Built prototypes to flesh-out requirements and gather feedback. Built flow diagrams to drive clarity for product and engineering team. Delivered final visual specifications, and collaborated with engineering team.

Visual Design

The pattern library I had been building was designed with our clinic-facing products in mind. I scaled the pattern set to include touch-friendly components for our mobile-first patient experience. The result was a cohesive library of components, many of which could be shared across patient and clinic experiences. My goal was to create a consistent visual library that could be applied by the development teams across all our products.

Flow Diagrams

Distilling complex user flows into diagrams helps gain clarity. I created several user-flows for Health Tracker that were shared with the product and development teams during story writing, planning, and development.


Clickable prototypes are a great way to user test, and drive further clarify for user-flows. My process involves working between user-flow diagrams and clickthrough studies to help uncover missed requirements, and refine the experience – while building scenarios for testing.

Content Strategy

A content-first methodology provides a stable ground to help us build more usable interfaces. Below are examples of documents I created during the design process, to help gain language clarity among teams and stakeholders.
