About Circular Health
At Circular Health, we understand firsthand what it means to navigate a complex illness without a clear roadmap. That's exactly why we built this platform.
Circular Health isn't just another app—it's the system we wish existed when we began our own journeys through chronic illness. We're here to empower patients with clarity, insight, and control over their care.
