The challenge

What needed to change

The client’s consumer banking apps had grown feature by feature on separate iOS and Android codebases. Everyday tasks such as checking a balance, paying someone or reviewing a transaction took too many steps, and the two apps behaved differently.

Customers noticed. Engagement was slipping and app store reviews pointed to confusing navigation. The client needed a modern, consistent experience on both platforms without compromising the security and reliability expected of a financial product.

Our approach

How we delivered it

Step 1

Research the everyday journeys

We reviewed analytics and customer feedback to identify the handful of tasks people perform most, then designed the app around them.

Step 2

Design a clear system

A new UI/UX design system defined components, accessibility standards and interaction patterns, prototyped and tested before development began.

Step 3

Rebuild on one codebase

Both apps were rebuilt in React Native, giving iOS and Android users the same experience and the client a single codebase to maintain.

Step 4

Streamline data and security

A GraphQL layer fetches exactly the data each screen needs, while biometric sign-in and secure session handling protect every account.

Results

The outcome

  • User retention increased by 42% after launch of the redesigned apps.
  • The app earned a 4.9★ rating on the App Store.
  • iOS and Android users now share one consistent experience built from a single codebase.
  • The client’s team ships updates to both platforms together, from one design system.
