The Croatian National Bank, as the central monetary institution of the Republic of Croatia, plays a key role in maintaining the stability of the financial system, managing monetary policy, and supervising credit institutions—one of the segments in which the CNB is increasingly actively communicating with citizens and businesses is the digital accessibility of information, and it is precisely in this context that the mHNB mobile application gains special significance as it enables the general public to access various financial data, educational content, and tools for monitoring market indicators. Prolink is involved in the development of this application, which serves as a channel of transparency and direct communication between the regulator and users of financial services, thereby further strengthening citizens' trust in the institution that manages the country's monetary system—the application is not just a technical solution but also a bridge between complex financial data and ordinary users who need quick and simple insight into information important for their everyday financial decisions.
Technology specifics and a modern approach to development
The mHNB mobile application is being developed within the Ionic development environment, which is based on proven technologies such as HTML, CSS, and JavaScript and enables the creation of cross-platform applications from a single code base—on this project, Prolink is using the sixth version of the Ionic framework, which brings a number of improvements in terms of performance, responsiveness, and support for modern mobile operating systems. This version enables deeper integration with the tender design and security standards required by the CNB, and the advantage of this approach is efficiency in development and consistency of user experience across different devices—whether on Android or iOS platforms, users get an identical experience and functionalities without compromise, which is especially important for an institution that must guarantee equal access to information for all citizens regardless of the type of device they use.
API access and reliable data availability
For the mHNB application to fulfill its functional purpose, access to accurate, up-to-date, and secure data that the CNB regularly publishes is necessary—as part of the project, Prolink has been provided access to the official CNB API, which enables the retrieval of data such as exchange rate lists, macroeconomic indicators, inflation rates, and other important information of significance for citizens and businesses. This data forms the foundation for the informative and interactive functionalities that the application offers to end users, and the API is documented and technically optimized to enable stable and secure communication between the application and servers—thus minimizing the possibility of errors and system downtime, which is of exceptional importance for an institution whose data influences the financial decisions of thousands of citizens and companies throughout Croatia.
Design, documentation, and visual interfaces aligned with institutional identity
In the application redesign phase, significant emphasis is placed on user experience (UX) and the application's visual identity (UI)—the Croatian National Bank has provided all necessary graphic files and documentation defining the structure, content, and visual guidelines for the new interface, and Prolink's designers carefully implement these guidelines to ensure the final product is fully aligned with the CNB's institutional identity. Design elements are developed to enable simple, clear, and logical navigation through the application, with special attention paid to readability, color contrast, accessibility for people with special needs, and display optimization on different types of devices and screen sizes—every detail, from typography to element layout, is thoughtfully considered with the goal of providing users with an intuitive and pleasant usage experience.
Security and reliability standards as a fundamental priority
Given the regulatory status of the Croatian National Bank and the nature of the information the application uses and displays, system security is set as one of the project's fundamental priorities—in every development phase, information security measures are implemented, including communication encryption, user authentication, protection against unauthorized access, and access control to sensitive data. In addition to technical aspects, Prolink pays attention to the procedural framework defining how data is processed and who has access to certain functionalities—this ensures that the application is not only technically correct but also fully compliant with regulatory requirements, including personal data protection regulations that are particularly strict when it comes to institutions of public importance.
Development in the context of real user needs and behavior patterns
The goal of refreshing the mHNB application is not just design modernization or technical improvement of existing solutions but also deep adaptation to user expectations and habits—through analysis of previous usage, Prolink's team has identified user behavior patterns, most sought-after information, and potential ambiguities in navigation and content presentation that need to be eliminated. Based on these findings, development priorities have been redefined and elements planned that should enable faster access to information, more intuitive searching, and greater interactivity—ultimately, the user must feel concrete benefit from using the application, whether through better information about exchange rates and economic indicators, easier monitoring of financial trends, or increased security in accessing official data sources of public importance.
Long-term vision and continuous application development
The mHNB mobile application modernization project represents an important step towards strengthening the digital capacities of one of the most important institutions in the Croatian financial system—its significance goes beyond mere technical implementation as it is a project reflecting the need for accessibility, precision, and responsibility in communication between the regulator and citizens. The future includes further functionality development, continuous monitoring of user feedback, and adaptation of the application to changes in the financial and regulatory environment—the mHNB application thus becomes a permanent tool for informing, educating, and digitally connecting the central bank with the public, a tool that will grow and develop together with user needs and technological progress.
Why the Croatian National Bank chose Prolink for application development
When selecting a partner for the development of this strategically important application, the Croatian National Bank sought a team that not only possesses top technical competencies in developing cross-platform mobile solutions but also deeply understands the specifics of working with financial institutions and the importance of data security that comes to particular expression in such a context—Prolink emerged as the natural choice precisely because of its holistic approach to development, where emphasis is placed not exclusively on technology but on creating a tool that will truly improve the institution's communication with the public and enable citizens easy access to the information they need. Throughout the entire development process, from initial analyses and architecture definition to implementation and testing, Prolink acts as a partner who listens, understands, and proposes solutions exceeding initial expectations—while simultaneously ensuring the application is intuitive to use, technically reliable, and ready for further upgrades that will bring additional value in the years to come.
