Digital behavioral health
Creating a brand-new iOS and Android experience for myStrength.
Overview
myStrength is a digital behavioral health platform that gives people tools and resources to manage depression, anxiety, substance use, stress, and other conditions. The responsive web app was modern and feature-rich, but the native iOS and Android apps had been neglected for years, falling behind on both usability and functionality.

The problem
The legacy mobile apps had drifted out of step with the web experience. Features were outdated or missing entirely, and the interface felt disconnected from the myStrength brand. The result was friction, low satisfaction, and weak engagement.
Patching wasn’t enough. We needed to rebuild from the ground up to match the product vision and what members had come to expect.
Process
We brought in Zurb to kick the project off with usability research and prototyping. The goal was to pressure-test our assumptions about how members actually used the web platform, then find the openings to translate that into a native experience that felt purpose-built for mobile. The engagement gave us sharp insights, a validated prototype, and a clear direction forward.
We scoped an MVP for the first release and mapped the enhancements that would follow in phases. As the only designer on the project, I led it end to end, from research through production-ready design. Development ran in parallel: while engineering stood up new APIs, I designed the core screens in the myStrength visual language and established a lightweight mobile design system to keep things consistent as the app grew.
To get from concept to production-ready, we used Sketch, Marvel, Haiku, Lottie, and Zeplin to prototype interactions, test animations, and hand off polished, build-ready assets.
Every feature moved through a sprint-based design and QA loop. That rhythm kept product, design, and engineering tightly aligned and kept the release on schedule.
Results
We shipped brand-new native iOS and Android apps within 12 months, on time and with every scoped feature included. Alongside the rebuild, we rolled out a new sleep program built for web and mobile at the same time. For the first time, the mobile experience reached full feature parity with the web, and it earned solid ratings across both app stores. The lightweight mobile design system left the team with a foundation to keep building on.
