The newest tool for internationally acclaimed organizing guru Marie Kondo in her global battle against messy rooms is an app.

"My goal is to have as many people as possible who can get the job done in tidying up," she said in an interview after speaking at the South by Southwest technology conference in Austin, Texas, over the weekend.

"To achieve that, I'm implementing various measures, one of which is the app to support decluttering," said the woman whose name has been turned into a verb by followers who clean out clutter at home and say that have "Kondoed" their closets.
