I design the apps millions of people
use to get care and stay connected.

I'm Darwin Provance, a healthcare product designer. I make health plans, care teams and clinics easier to reach for Rightway, Carium and ZoomCare.

Health care first

I specialize in design for health. From choosing a benefits plan to following a care plan to seeing a doctor today, I turn clinical complexity into products people open every day.

Selected work

Trusted with products
used by millions.

Get in touch

Three healthcare products and two telecom apps. I work from research with patients, clinicians and members through design systems, prototypes and launch, and I measure what changes. Open a project for the full case study.

How I design for health
01

Design for the worst day.

People open a health app when they're sick, worried or confused. The urgent task comes first, at 2 AM, one-handed.

02

Warm beats clinical.

A care plan should feel like a companion. Friendly progress, plain words and feedback that builds trust.

03

Plain language is a feature.

Deductibles, care plans and bills get translated into what it means for you and what to do next.

04

Always a way to a human.

A doctor, a care team or a Health Guide is never more than a tap away, and you always know who you're talking to.

05

Then measure it.

Daily use, satisfaction, adherence and missed appointments tell me whether the design worked.

Health care · Now

Rightway

The member experience for a company that helps people understand their benefits and find the right care, with real Health Guides behind the app.

The challenge

Open enrollment asks people to choose a health plan from documents written for insurers. Members need a straight answer to "which plan costs me less?" and a person to talk to when the answer isn't simple.

What I'm designing

An AI benefits assistant that answers plan questions in plain language, compares plans in a single card and hands the conversation to a Health Guide. I also design account registration, so that proving who you are takes as few steps as possible.

Design decisions

One comparison card with a one-line takeaway replaced long tables and repeated numbers. Plans sit side by side on web and stack on phones. The handoff always tells the member who they're talking to.

Carium

I led the redesign of a digital health platform that connects patients with their care teams, from concept to launch on mobile and web.

The challenge

Health communication was fragmented, and wellness tools felt clinical. I ran research with 24+ patients, clinicians and caregivers, then rebuilt the information architecture around simple onboarding, care-team messaging in context and gradual data collection.

What I designed

A design system of 47+ reusable components with layouts that adapt from phone to desktop. A personal dashboard with friendly progress indicators, video visits that keep the warmth of in-person care, and structured messaging between patients and care teams.

The result

Within six months daily active users rose 85%, satisfaction went from 67% to 92%, adherence improved 3.2× and no-shows fell 40%. The system now supports AI-powered health insights and chronic disease management.

ZoomCare

A complete mobile healthcare app: same-day appointments, chat with an MD and health records, for urgent, primary and specialist care.

The challenge

Traditional care means hours in a waiting room or weeks for an appointment. Through user research and competitive analysis I mapped every point of friction between feeling sick and seeing a provider.

What I designed

Wireframes through high-fidelity prototypes for same-day scheduling, real-time chat with providers, health records and finding a clinic nearby. Symptom flows route patients to the right specialist, whether it's urgent care at 2 AM or a follow-up.

The result

A design system serving both patient apps and provider workflows. It supported the "wait-less" model ZoomCare pioneered and helped establish it as a leader in convenient care.

Mint Mobile

Usage tracking, multi-line management and plan recommendations that make wireless pricing easy to understand on iOS, Android and web.

The challenge

Wireless apps are known for confusing screens and hidden fees. I research where customers get lost in plans, usage and billing, and design toward interfaces that feel honest.

What I design

Usage dashboards, multi-line management and personalized plan recommendations. Clear hierarchies surface savings, and smart notifications warn people before overages.

The result

Fewer support inquiries about plan confusion and more use of cost-saving features, for millions of active customers.

Ultra Mobile

International calling, roaming controls and plan tools that help families stay in touch across borders.

The challenge

Ultra serves immigrants, travelers and global communities who face high international rates and complicated offers. I worked with multicultural user groups to design for language barriers and cultural nuance.

What I designed

International calling, multi-currency plan management, roaming controls and community features, with clear rate indicators and simple country selection.

The result

Cost-transparent interfaces and notifications that prevent surprise charges, keeping families, friends and businesses connected across continents.
