MERCURY
OVERVIEW
Mercury unified five separate transit apps into a single, delightful super-app used by 2.8 million daily commuters across three European cities. The challenge: different data schemas, real-time constraints, and wildly different user mental models.

THE CHALLENGE
Users were juggling five apps to get from A to B. Each app had its own UX logic, account system, and payment flow. Churn was 38% within the first month — users simply gave up.
THE SOLUTION
A single, unified interface with an intelligent trip planner at its core. We designed a motion-first experience: transitions communicate progress, micro-animations reward action. A React Native codebase shared 80% of logic between iOS and Android.
