Family carers encounter several challenges related to caring for people with dementia, and they need support in managing care recipients' health needs. This study aims to identify, appraise and synthesise the existing evidence on the use of mHealth/smartphone applications as an educational and supportive resource for family carers of people with dementia. An integrative literature review approach was used. Seven databases were searched. The search generated 117 articles, with seven meeting the inclusion criteria. Three categories and their attendant sub-categories emerged from the literature. The categories are 'carer support', 'evaluation strategies' and 'barriers and challenges'. mHealth applications appear to be a feasible intervention for family carers of people with dementia despite the limited available research and barriers for their development and implementation. Further research on mHealth applications with strong methodological rigour and more research on mHealth applications as an educational and supportive resource for carers of people with dementia are needed.
