Legacy App Rewrite

Smart Region Limburg (s-Lim), a collaboration of local governments, needed to reduce fragmentation in municipal communication and services across multiple municipalities. ACA Group developed Mijn Stadsapp, a cross-platform mobile application built with React Native that integrates data from various sources such as municipal websites, event platforms, and utility services. This solution centralizes local information and services in one app, improving citizen engagement and accessibility, and achieved rapid adoption with over 20,000 downloads in the first month.

Ecofix, a Belgian energy start-up, needed a complete digital platform to support its launch and offer transparent dynamic energy pricing. ACA Group delivered end-to-end digital product development, including branding, a mobile app, and a website, using Flutter for cross-platform development and Microsoft Azure Cloud for scalability and security. Delivered within weeks, this solution enabled rapid time-to-market, provided customers with real-time energy insights, and established a scalable digital foundation for Ecofix’s growth.
