Why CZ Reinvented Their Mobile Experience 

As digital interactions become the primary point of engagement for customers, ensuring a seamless mobile experience is critical. CZ Zorgverzekeringen, a leading Dutch health insurance provider, sought to enhance its mobile app to deliver a more efficient, user-friendly, and scalable experience. Partnering with Sopra Steria, CZ leveraged Google Flutter to create a multi-platform app that improved customer satisfaction, simplified maintenance, and optimised costs. 

The Turning Point: Outgrowing Low-Code 

With an increasing number of policyholders using mobile apps to manage their health insurance, CZ recognised the need to provide a modern, high-performance application that works seamlessly across iOS and Android. With the previous low-code solution, only a limited set of platform features was available, and there was a delay in delivering new features, which restricted the ability to develop a modern mobile application.  With the previous low-code solution, only a limited set of platform features was available, and there was a delay in delivering new features, which restricted the ability to develop a modern mobile app. CZ aimed to unify its digital experience while maintaining high-security standards and ensuring a frictionless user experience. 

What Happened When CZ Chose Flutter 

CZ faced the challenge of delivering a consistent, fast, and reliable mobile experience while optimising development resources. By adopting Flutter, CZ successfully transitioned to a single-codebase approach, reducing complexity and enhancing agility. The new application improved customer engagement, increased the average app rating, and elevated the Net Promoter Score (NPS). Sopra Steria’s expertise in mobile development and co-sourcing approach ensured a smooth implementation and continuous optimisation.
