This study sought to investigate digital health tools and technologies dimensions for equitable access to health, including Universal Health Coverage in developing economies. Universal Health Coverage (UHC) is a promise of accessible and high-quality healthcare, which addresses coverage of essential health services and catastrophic health spending, in line with goal 3 of the United Nations Sustainable Development Goals (SDGs). However, the problem of inequitable access to health, including UHC, continues to plague the entire endeavour, even with notable technological advancements among the population and within the health sector. This study uses a narrative literature review methodology to investigate the dimensions of digital health tools and technologies for equitable access to health, including UHC. The findings from this study identify internet access, availability of internet, availability of a smart device, and device access to digital content as key dimensions for equitable access to health, including UHC in developing economies, and in line with digital health tools and technologies. Considering these dimensions will ensure that developed and deployed interventions are available and accessible to the majority of the population. Ultimately promoting digital health and equitable access to health, as well as ensuring that key dimensions of digital health tools and technologies are not assumed.
