Yik Yak is a social media smartphone application. It is available for iOS and Android and it allows people to create and view discussion threads within a 5-mile radius (termed "Yaks" by the application). It is similar to other anonymous sharing apps such as Nearby, but differs from others such as Whisper in that it is intended for sharing primarily with those in proximity to the user.[not in citation given] All users have the ability to contribute to the stream by writing, responding, and "voting up" or "voting down" (liking or disliking) yaks. The developers of the app, Tyler Droll and Brooks Buffington, are both graduates from Furman University in Greenville, South Carolina. The two started collaborating when they were placed into the same class where they learned how to code iPhone apps. After graduating from Furman University, they decided to go full-time with the project. Droll dropped out of medical school just before it started and Buffington put his finance career on hold. The two released the app in November 2013, and twelve months later, it was ranked as the 9th most downloaded social media app in the United States. Droll and Buffington have continued their work on Yik Yak, taking measures to ensure its sustainability. On January 20, 2016, Yik Yak announced the web version of the app is available.
