Information and communication technologies (ICTs), as learning tools, promote a shift towards new educational processes through didactic and pedagogical frameworks that go beyond traditional approaches. Their use transforms the concepts of interactivity and information empowerment. In this context, equipping future teachers with a wide range of tools, including apps, is essential for improving learning and raising awareness about cultural heritage. One such app, CatPat, was developed in 2022 by the Argos Research Group at the University of Zaragoza. This work examines its impact on pre-service primary school teachers at both the University of Zaragoza and the Public University of Navarra. The study uses an action-research methodology with a sample size of n = 143 and mixed-methods analysis employing custom-designed, validated questionnaires. The results align with the research objectives and demonstrate that students attribute significance to ICTs in heritage-related interaction and socialisation and recognise the CatPat app as a valuable tool for teaching and building heritage cybercommunities.
