Background <p>Computerised cognitive testing offers potential for large-scale cognitive assessment and may support the identification and monitoring of early cognitive impairment, while reducing clinical burden on healthcare staff and improving efficiency.</p> Methods <p>Three focus groups, comprising members of the public, clinicians, commissioners, business leaders, and academics, were conducted using a semi-structured interview guide addressing acceptability, engagement, benefits, risks, and adoption. Data were analysed using thematic analysis.</p> Results <p>Participants identified that the successful implementation of an interactive cognitive monitoring app would depend on its acceptability, perceived usefulness, sustained engagement, accuracy and appropriate interpretation of information, robust data security, and potential efficiency gains within the health and care systems. Perceived benefits for individuals include reassurance, reduced stress, early access to assessment and support, as well as the potential to maintain quality of life. For clinicians and the health system, perceived benefits include improved efficiency through reduced consultation times and shorter waiting lists.</p> Conclusions <p>The findings align with existing literature on earlier identification of cognitive decline and digital cognitive assessments, highlighting the potential relevance of such technologies for supporting service delivery and enhancing efficiency within cognitive health care.</p> Trial Registration <p>Not applicable.</p>
