Women do more than double the amount of chores than men.
Females are normally responsible for 56 out of 80 household jobs, while men are in charge of just 23 - research from the housework app Choreful has revealed.
The only task that both sexes share is shopping for treats for the children.
The app's inventor Robin Havre said: "It all started as a joke. My girlfriend kept complaining that I wasn't doing enough around the house.
"Totally convinced that I was doing as much as her - if not more - I thought it would be funny to make an app to log the housework.
"I have to admit that I was a bit embarrassed by how little it showed me as doing. The first reading said I was only during 39 per cent."
Havre says he has taken on more household jobs since the app's revelations.
He said: "Now me and my girlfriend are actually sharing the housework 50/50.
"I'm hoping the app will have this impact in other homes too. I hope it will help motivate couples, flatmates and families towards a more equal relationship."
