The app, developed by the Centre for Addiction and Mental Health in Ontario, Canada, helps users identify drinking behaviour, set personal goals and track their progress when it comes to drinking.

"This is a way of helping people set their goals and give them feedback," Wayne Skinner, deputy clinical director of the centre, was quoted as saying in the Toronto Sun.

Named "Saying When", the app outlines low risk drinking guidelines and has links to outside resources to help people recognise patterns of problem drinking.

"It is really not just about stopping the behaviour but it is about making successful behaviour change," Skinner added.
