About

Y/n is the most entertaining app in the world. On Y/n, you play a character in a story. Be a boarding school transfer student and get the boys to fall in love with you, or figure out a jailbreak with Sherlock Holmes. Your choices change the story and how characters feel about you (oops!) – so no two playthroughs are the same (but you can rewind). ■ Play interactive romance, drama, fanfiction, mysteries, fantasy, fluff (or angst), and more. ■ Discover 1M+ stories written by the community. ■ Write and publish your own interactive stories. Download Y/n and try for yourself!
