Yik yak is an anonymous social media app. it is available for ios and android and it allows people anonymously to create and view "yaks" within a 10 mile radius. it differs from other anonymous sharing apps such as postsecret and whisper in that it is intended for sharing primarily with those in close proximity to the user, potentially making it more intimate and relevant for people reading the posts. all users have the ability to contribute to the stream by writing, responding, and liking or disliking yaks. the developers of the app, tyler droll and brooks buffington, are both graduates from the liberal arts college of 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 med school just before it started and buffington put his finance career on hold. the two released the app in november 2013, and six 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.
