 The study investigates the adoption and attitudes towards the NHS COVID-19 smartphone app, a digital contact tracing solution in the United Kingdom. The results show that while around half of participants who had heard of the app had downloaded and kept it, more than one-third either did not intend to download it or had deleted it. Significantly more BAME respondents than white respondents had deleted the app, and significantly more older adults 65 years, and over than those under 65 years did not intend to download it. The study highlights that issues surrounding trust and understanding hindered adoption, particularly among BAME communities, and that more needs to be done to improve uptake and acceptance of contact tracing apps among vulnerable populations.
