The Croatian National Bank, as the central bank of the Republic of Croatia, plays a key role in ensuring transparent, accurate and timely information related to the monetary system and financial stability. The EURO.hr mobile application is one of the digital channels that extends this function to citizens — providing easy access to relevant information about the euro, the financial system and the regulatory framework via mobile devices. The maintenance and further development of the application was entrusted to Prolink as a partner with the necessary technical knowledge, experience in working with public institution applications and an understanding of the security and regulatory requirements that distinguish such projects from commercial mobile solutions. This is the second Croatian National Bank mobile application that Prolink continuously maintains — further confirming the trust placed in a long-term technical partnership.
Continuity of maintenance and technical responsibility
Maintenance of the EURO.hr application encompasses continuous care for the stability, availability and correct functioning of all features — an approach based on systematic monitoring and timely response to technical changes, rather than one-off interventions that address problems only after they become visible to users. Particular attention is paid to compatibility with new versions of the iOS and Android operating systems, which Apple and Google regularly release and which each time bring changes that can affect the functioning of the application if not addressed in a timely manner. Regular updates ensure that the application remains reliable and functional in a dynamic mobile environment where technical requirements change faster than in any other digital domain. For a public institution application that serves as a reliable source of information for citizens, continuity of maintenance is not an option but a fundamental prerequisite.
Functional and technical optimization
As part of the maintenance, a detailed analysis of the existing application features was carried out with the aim of identifying areas for improvement of the user experience without disrupting the consistency and recognizability of the solution. The content structure and navigation logic were analyzed to ensure simple and intuitive use for a wide range of users — from the technologically savvy to those who use mobile applications occasionally and for whom every unnecessary navigation step represents an obstacle. Optimizations are focused on improving the clarity and speed of access to information, because for an informational application, the speed of finding relevant content is the key indicator of usefulness. The goal was not a visual redesign but a functional improvement that makes the application genuinely usable and that fulfills its informational purpose in the most direct way possible.
Security standards and system stability
Security and stability are the fundamental requirements in maintaining applications of public institutions — requirements that have a higher level of strictness than for commercial applications because the institutions in question have a direct impact on public trust through their reliability. The EURO.hr application is regularly aligned with current security standards, with particular attention paid to the protection of communication and the integrity of data distributed through the application. System stability is ensured through testing on various devices and usage scenarios that simulate the real conditions in which users access the application — from different operating system versions to different network conditions and screen sizes. A preventive approach that identifies problems before they become visible to users is a fundamental characteristic of responsible maintenance of a public institution application.
Preparation for distribution via mobile stores
Application maintenance also includes continuous preparation for distribution via the Apple App Store and Google Play — distribution channels that have their own rules, technical requirements and security standards that regularly change and with which the application must comply in order to remain available to users without interruption. Each new version goes through testing and compliance verification procedures before release, with particular attention paid to security permissions and technical requirements that differ between the App Store and Google Play and that change with new platform versions. Timely adaptation to these changes is key to stable distribution, as delays in compliance can result in temporary unavailability of the application, which for an institution like the Croatian National Bank is not acceptable.
Experience as the foundation of long-term partnership
Maintenance of the EURO.hr application builds on previous experience working on another Croatian National Bank mobile application — continuity that gives Prolink a deeper understanding of institutional requirements, the regulatory context and the specific expectations that the Croatian National Bank has of technical partners working on its digital channels. Experience gained through the maintenance of complex public digital solutions with high requirements for security, stability and reliability is applicable to all projects where a technical partner must understand not only the code being maintained but also the institutional responsibility that stands behind the digital channel powered by that code. If you are considering a long-term technical partnership for the maintenance of a mobile or web application for a public institution, we are here to discuss an approach that meets your specific needs and standards.
