Using a mobile health application (i.e. app) to empower primary caregivers of young children with developmental disorders in low- and middle-income countries is opening up new avenues for early childhood intervention. Thirteen caregivers and ten speech-language pathologists participated in three focus groups to explore their perspectives about the potential benefits and suitability of a mobile health app as part of intervention, its features, the likelihood of using and recommending it, as well as potential pitfalls to be avoided.
