About Me

In October 2020, I was diagnosed with a rare and aggressive blood cancer. Overnight, life became a sequence of appointments, lab results, side effects, and questions—most of them unanswered. Like many patients, I was expected to remember everything: how I felt yesterday, when a symptom started, what changed, what mattered, what didn’t. The burden of tracking my own health quietly became part of the illness itself.

What surprised me most wasn’t the diagnosis (although, admittedly, that was a huge punch in the gut for a healthy 40-something); it was how fragmented care felt once treatment began. Symptoms lived in conversations. Patterns lived in memory. Context lived nowhere. The system wasn’t built for continuity, privacy, or reflection. It was built for transactions.

Symptom Keep exists to change that.

I’m a product designer by trade, with decades of experience building complex systems in healthcare, finance, and education. But this wasn’t a design challenge. It was a human one. I needed a way to own my experience without surrendering my data, my agency, or my dignity. I needed something simple, quiet, and trustworthy. When I couldn’t find it, I decided to build it.

3-ring binder with symptom notes, calendars with hand written notes, and some wireframe mockups and flow diagrams laid out horizontally.

This app is shaped by lived experience. It’s designed for people navigating cancer, chronic illness, and long recovery arcs—where progress isn’t linear, and symptoms don’t arrive on schedule. Every choice reflects a belief: that patients deserve tools that respect their privacy, reduce cognitive load, and help them see themselves clearly over time.

Symptom Keep is not about optimization or surveillance. It’s about presence. It’s about patterns. It’s about giving patients something solid to hold onto when everything else feels uncertain.

Symptom Keep didn’t start as a startup idea.
It started as a necessity.

Today, I volunteer with the cancer community and continue refining Symptom Keep alongside clinicians, caregivers, and survivors. The goal is simple, even if the work is not: to help people track what matters, make sense of their journey, and show up to care conversations with confidence.

This isn’t a platform built around patients.
It’s built with them—starting with me.

Sincerely,

Anthony Rezendes
