Problem
Roche’s digital biomarker product faced low user adherence and retention, limiting its clinical and business impact. Despite strong underlying science, patients disengaged over time, reducing data quality and long-term value. The challenge was not feature gaps, but a lack of behavioral alignment, feedback loops, and engagement mechanisms suitable for a global digital health product.
The Work
We conducted a full product audit to identify behavioral, UX, and engagement breakdowns, then transitioned into hands-on research and design. The work included rapid behavioral prototyping, iterative UX/UI improvements, and a full rebuild of the solution in Unity to enable fast experimentation, testing, and iteration. The focus was on validating engagement strategies before scaling globally.
My role
I worked as a hands-on designer throughout the engagement, responsible for translating research insights into shippable product solutions. I was directly involved in designing and iterating on core user flows, applying gamification and behavioral design patterns to improve adherence, and harmonizing the experience across the mobile app and the desktop portal.
Alongside research and testing, I executed UX and UI changes end to end, ensuring concepts validated through experimentation were delivered consistently and at scale.
Outcomes
The experiments and improvements delivered measurable impact at scale:
20× increase in re-engagement from dormant users
3.4× increase in overall retention
2.1× increase in tasks completed within the app
The product shifted from low adherence to sustained engagement, validating a scalable approach to behavioral design in digital health.
