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 The visual design was inconsistent and outdated.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 are currently gathering feedback from our beta launch in September 2019. We have already heard from both patients and caregivers that Health Tracker is more intuitive and easy to navigate. We will continue to test and learn from our users, as we prepare for further refinements.

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.
