A popular hashtag has just been translated into a free app that allows consumers to share products or advertisements that market using gender stereotypes. The "Not Buying It" hashtag was turned into an app by the campaign to challenge media sexism, Miss Representation.

App users can take a picture of a product or add, brand it with "not buying it" and share with companies as well as the public.

Miss Representation raised more than $20,000 through crowdfunding to produce the app. 

According to Miss Representation, the companies most often accused of sexism and gender misrepresentation with the "not buying it" hashtag are Go Daddy, Audi, American Apparel and Disney.
