Before and After: The Mobile Banking App That Cut Clutter and Raised NPS

Tech · 4 min read

The bank's legacy app aggregated every product tile, push notification, and marketing banner on a single scrollable home screen. Customers reported difficulty finding frequent tasks like transfers and bill pay. The UX team began with card sorting sessions and quantitative click-path analysis to identify the 80/20 tasks for 90% of active users.

The redesign prioritized task-based triggers: a compact quick-actions bar, contextual widgets that surfaced only relevant products (e.g., mortgage payments on mortgage due dates), and a single universal search at the top. Visual hierarchy was simplified with fewer competing CTAs and a consistent card size system.

After deployment, weekly active users engaged with quick actions 3x more than before; time-to-complete common tasks dropped by 40%, and the app’s NPS rose by 9 points. Marketing spend for in-app product discovery also decreased because discovery was now contextual and non-invasive. The project demonstrates the ROI of decluttering and designing around primary user intents.
