Overview
Helping Patients Track a Slow-Progressing Cancer
The client needed a better way to support patients with Polycythemia Vera (PV)—a slow-developing type of blood cancer where symptoms and medication effects are often subtle and hard to track over time.
To solve this, I designed a PV symptom tracker app that empowers patients to actively participate in their care. The app allows users to log symptoms and side effects in real time, helping them build a clearer picture of how their condition evolves and how treatments are affecting them. This not only improves communication with healthcare providers but also supports early intervention and better medication adherence.
By applying user-centered design principles, I created an experience that is empathetic, intuitive, and engaging. From personalised symptom tracking to clear, actionable data visualisations, every element of the UI is crafted to support users in taking control of their health journey.

User Interviews
After talking to the representatives from Novartis and the patients, we discovered that PV patients struggle with monitoring their health over long period of time. In addition when they come to the doctor they don’t have all the analysis they’ve collected over the years. So we wanted to give them a space where they can track their blood work, symptoms and overall mood over the years in one place.
User Stories
To make sure all the information provided is relevant, I’ve outlined the main user personas and wrote down the user stories to make sure the patients and the doctors will have relevant information prior the appointment.
Design
The prototype was completed within two months, including interactive elements and a lightweight design system for consistency and scalability. The symptom tracker is structured around four key components:
Introduction to the illness – offering patients a clear, accessible overview of PV
MPN10 quiz – a validated questionnaire to assess symptom severity
Mood tracking – helping capture the patient’s emotional well-being over time
Health dashboard – visualising logged symptoms and trends to support more informed clinical conversations
Dashboard
Symptom info
Users have an ability to scroll through their symptoms and see the annual fluctuations. They can also specify how they feel using the common phrases given by the patients prior sending the notes to their HCP.
Mood
Tracker
For the mood tracker, it was important to design a UI that resonates with users across different backgrounds and age groups. To achieve this, I drew inspiration from familiar weather metaphors—using simple, intuitive graphics to help users easily express their overall emotional state.
Accessibility
Accessibility and readability were critical considerations, as the primary users are often older adults. To support this, the symptom tracker was designed with enhanced data clarity and minimal visual clutter. Large text, clear labels, simplified graphics, and thoughtful use of colour ensure that information is easy to digest, while interactive features allow users to explore their health data at their own pace.
Conclusion
Overall, a PV symptom tracker serves as a valuable tool for enhancing pharmacovigilance efforts, promoting patient safety, and advancing our understanding of the real-world impact of medications. It enables healthcare providers to gain better insight into how patients are feeling over time, helping them identify and address subtle, slow-developing symptoms—ultimately improving the quality of life for those living with PV.
