The "Drink Less" app aims to help users change their attitude towards drinking and allows them to track their drink consumption.
Claire, the chief investigator on the trial, acknowledged health apps "don't suit everyone" however said:
"By making tools, like Drink Less, readily available and integrating them into existing healthcare systems, we can not only improve people's individual health outcomes, but also contribute to a more equitable and healthier society.
"We need a national strategy to address alcohol harm that also includes other effective interventions and policies, such as making alcohol less cheap and less available, less heavily marketed, and improving access to alcohol treatment and support."
