Based on interviews with a number of patients with TTP and clinicians that treat TTP, we learned about the constant hyper-vigilance that is required of TTP patients and the immense amount of stress that adds to their daily lives. We wanted to ease that stress through creating a simple way for patients to track their symptoms and report back to their doctors, who can then accurately adjust their treatment. By rigorously thinking through our user flows and building a design system based on Apple's Human Interface Guidelines, we created features like a symptom logbook, a resource browser, and effective tutorials for navigating through it all.

One of my favorite parts of the project was delving into my inner cartoonist while developing page components and icon systems. One of the most common insights we heard from folks with TTP was how "cold" or "sterile" everything they had to interact with felt. To bring a sense of warmth and friendliness to an otherwise pretty heavy, clinical space, I created an approachable character that leads the user through onboarding and provides tips throughout the experience. The organic, bubbly aesthetic of the app helps to promote a sense of comfort when dealing with something that can often feel quite grave and serious. I also created icon systems for both characterizing general discomfort level as well as indicating almost 30 other symptoms. See if you can guess what they all mean!
