While early childhood educators’ use of digital applications (apps) to document children’s experiences and support parent communication is increasing, there is limited empirical research about the impact of these applications on children’s experiences and educators’ practices. This article provides a critical analysis of the findings from this body of research with a focus on affordances and challenges. While the research supports potential benefits for parent engagement and pedagogy, a range of challenges relating to content, access, equity, workload and ethics are highlighted. Features of the neoliberal contextual that may enable the increasing use of apps and shape the way they are used are considered, and opportunities for future research to further critique, enhance understandings and inform practice proposed.
