Relay

Inspiration

I wear a Garmin and have for a while, but I never really did anything with the data it collects. That got us thinking about how much health data people already have and how little of it actually helps them. One of our teammates also wanted to make navigating healthcare appointments easier, and we learned that MassHealth renewal notices often miss the people who need them, so they can lose coverage without ever realizing it

What it does

Relay has a patient view and a clinic view. Patients can share wearable vitals with their doctor in a simple view and PDF that shows raw data only and never makes a diagnosis. Clinics post open appointment slots, and the patient who has waited the longest gets notified first, so the waitlist is fair. Relay also tackles a problem with MassHealth, the state health insurance. Renewal notices are mailed, and a lot of people miss them, so they can lose coverage without realizing it. Relay gives patients a MassHealth renewal countdown that shows how many days they have left to renew, so the deadline doesn't depend on a letter getting through. It only reminds people. It never decides whether someone is eligible. Finally, Relay has an emergency mode that shows the nearest ER with no insurance filter, so anyone in a crisis can find care fast.

How we built it

We built Relay as a React and Vite web app with a FastAPI backend and a SQLite database. We used AI tools throughout, including Claude and Kiro, to plan the product, write and refine code, and design the interface. We worked together on a shared GitHub repo and used a wearable dataset to power the vitals features.

Challenges we ran into

Our biggest challenges were sorting out merge conflicts and figuring out how to work together on the same codebase. We also had trouble at first getting our datasets into the app and connecting them to the features.

Accomplishments that we're proud of

We are really proud of all the features we added and how helpful they could be for real patients and clinics. Getting everything working together as one product in a weekend felt great.

What we learned

We learned a lot about collaborating as a team and using GitHub to work together on one project. We also learned about full application design from front end to back end, and the different steps and processes that go into building one.

What's next for Relay

We want to keep building and refining Relay. One big idea is a permanent lock screen emergency tab that shows up when someone needs help and is unconscious or unable to use their phone, so responders can see what they need right away. We also have other ideas we want to add as we keep improving it.
