One app for smarter cities in Croatia

Direct communication, real-time notifications, and all city services just a tap away: The OneCityApp from Hrvatski Telekom and Combis is helping make Croatian cities smarter.

CHALLENGE

The historic city of Split, which has 210,000 residents, and Vodice, a smaller coastal town in central Dalmatia with around 9,000 inhabitants, faced a common challenge: outdated communication between citizens and local administrations. Information and services were fragmented, difficult to access, and time-consuming to navigate. Put simply, they were struggling to offer efficient, inclusive access to municipal information and services—whether it was getting important messages to citizens or meeting their everyday needs.

SOLUTION

Hrvatski Telekom and Combis developed the OneCityApp—an integrated digital platform that brings essential city services together into one mobile application—to bridge this communication gap and bring modern services closer to citizens. Implemented in multiple Croatian cities, including Split and Vodice, the app provides citizens with personalized, location-based updates, real-time information, a digital payment hub, traffic solutions, parking options, and event calendars—transforming how these municipalities engage with their communities.

BENEFITS

  • Unified access to all city services in a single intuitive application
  • Improved engagement with local people and administrative efficiency

  • Direct and secure two-way communication between citizens and city administration using AI-assistance or directly through city services
