The government has launched a new smartphone app so drinkers can see what alcohol is doing to their “health, waist and wallet”.

The app, part of the Change4Life campaign, offers tips on how to limit alcohol intake - such as having alcohol-free days, not drinking at home before going out, swapping to low-alcohol or alcohol-free drinks, and using smaller glasses.

Guidelines say men should not drink more than four units a day - equivalent to two pints of lager - and women two to three. But over nine million drinkers in England regularly drink more and a YouGov poll found most people were unaware of the serious health problems caused by drinking.
