Drink Less is a smartphone app, freely available on iTunes, designed to help people reduce their alcohol consumption that was developed using a systematic and iterative process drawing on evidence and theory. The app has recently been optimised in terms of its effectiveness and usability based on an initial factorial trial, user feedback and further user testing as part of a funded project
