Control Health

Control Health connects a person's medical records, lab results, and wearable data in one place, adds an AI assistant that explains what any of it means in plain language, and turns that history into a lab panel built for them specifically. As primary product designer I owned onboarding, the health dashboard, the data hub, and the labs-ordering flow, the surfaces that decide whether scattered medical data becomes something a person can reason about.

The question underneath all of it: how do you make a decade of messy, incomplete, sometimes contradictory medical data feel like yours, clear enough to act on, without pretending to be a doctor?

Onboarding

Earn the connection before you ask for it.

Onboarding: connect health records and wearables, value shown first

Handing over a full medical history is the biggest ask, so onboarding shows the payoff before asking for a single connection. Records come first, since they're what make the answers about you, not the population.

Cold start

Design the empty state first, not last.

Cold-start state with a baseline Foundation Panel before records sync

Records take time to arrive and the picture is never complete, so I designed the empty and partial states first. A baseline panel gives someone a place to start before anything syncs.

Dashboard & chat

Ask your own records a question, in plain language.

Chat home screen with a collapsed connected-data band and suggested questions

The assistant already holds your labs, records, and wearables, so the home screen opens with a plain question box. Informational, not diagnostic, with most of the care spent on what it won't answer.

Personalized panels

Every recommendation shows its reason.

Personalized lab panel with a specific reason shown under each biomarker

Each suggested biomarker shows why it's there, pulled from your own data, so it reads as care, not an upsell. Rules, not a model, keep it reproducible and auditable.

Control

Add or remove anything, and the price updates live.

Browse-all catalog with a live panel cart and running total

The full catalog is one tab away, everything is removable, and the total updates as you go. That control is what makes people comfortable keeping the markers that cost the most.

Closing the loop

From recommendation to booked draw, in one flow.

Scheduling a lab visit with a booked-visit confirmation

Checkout flows straight into scheduling, with nearby labs and real appointment times, so the loop closes inside the product instead of a handoff to a phone number.

Prep guide

Show up prepared, so the draw is right the first time.

Prep guide panel with fasting instructions and a night-before and morning-of checklist

A panel is only as good as the draw behind it. A prep guide walks each person through the night before and morning of, tuned to the tests they ordered, so nothing has to be redrawn.

Outcome

A working consumer-health product, live at controlhealth.ai, built to hold real clinical complexity and stay readable to someone with no medical training.

For a pre-launch product, the honest measure is what the design made possible: medical data a person can reason about, and a recommendation surface people trust because every line explains itself. The patterns underneath, for empty states, messy records, and traceable sources, will hold up as more data arrives.
