Wattpad is a free app that lets you read and share stories with people around the world. The platform started as a home for original fiction but soon became a place for users to post fanfiction as well. Although the web platform is most used by writers, 85% of all Wattpad activity is on mobile. Wattpad stories are available in over 50 languages.
As of March 2015, Wattpad has over 39,000 Supernatural fics, 302,159 Supernatural chapters/parts uploaded and on average 18.5 million minutes of Supernatural fic read each month. RPF and mature content is allowed on the site.
