Many children don't like doing chores. But asking children to do chores is more than just getting the house cleaned. It can also help children to be independent and responsible.
Luckily, there is an app to help. The app You Rule Chores lets kids get up from the sofa and do chores. Through smart phone games, the app turns children into housework helpers. “It is difficult to get kids to do work around the house. We made the app to teach kids self-control, which is very important to their future,” one of the app engineers said.
The games are fun, and the app is easy to use. You Rule Chores is my favourite chore app so far.
—Sam, a middle school student
You Rule Chores is an app the whole family will benefit from (从中受益). Now my kids often compete to see who can do more housework.
—Brooke, a mother of three kids.
Young kids like to help out around the house, but fewer parents hear the words “What can I do to help?” from their older kids. A study shows that only 65% of the kids aged 16 to 18 take part in chores.
How to use You Rule Chores? First, each child needs to choose one of the app's characters. Then the child can start to do chores. Once he finishes it, he can get some coins (硬币) from the app. He can use them to buy things from the online store.
