Interpersonal violence has devastating implications for individuals, families, and communities across the globe, placing a significant burden on health, justice, and social welfare systems. Smartphone technology may provide a platform for violence prevention interventions. This paper explores the evidence on the availability and user experience of UK smartphone applications aimed to prevent violence and improve personal safety. The findings have implications for the development of policy on applications to improve personal safety, especially given recent national policy (e.g. UK) discussions about their utility.
