Smart cities are fostering the interaction, collaboration and involvement of citizens in the city management models. To achieve this aim, technological tools like city mobile apps are being used for redefining the way citizens interact with smart cities. This paper seeks to analyse the demographic profile of citizens regarding the use of local government Apps for participation in public affairs and the digital divide through the evaluation, opinions and interest of citizens in these Apps in European smart cities. To achieve this aim, this paper focuses on an empirical research on Apps created by European smart cities included in the IESE Business School project. Findings indicate that the education level, gender and ages of the citizens can be factors to download, evaluate and opine about local government Apps, although its influence depend on the smart dimension in which the Apps are running.
