A new app has been designed to help young people cut down their drinking.
'DrinkSmart', developed by Social Code Limited with support from ACC, measures the cost of drinking in dollars and calories consumed.
Social Code founder Siobhan Bulfin said the app helped people harness social networks to stay focused and healthy, set achievable goals and keep motivated.
ACC spokesman John Beaglehole said many young people knew they were overdoing it and would like to cut back.
"But there are so many triggers, such as people, places and particular activities, that can cause you to drink more than you want to."
