Lumen Health Companion App
Lumen Health · 2025
A ground-up redesign of a digital bank's mobile app, now used by 1.5 million customers.
Vertex's app had a 2.9-star rating and a fragile codebase that made compliance updates risky. Younger customers were leaving for neobanks with better experiences.
We redesigned every core journey, rebuilt the app in Flutter with biometric authentication, instant payments and spending insights, and introduced feature flags so releases could ship weekly.
