Genius allows you to explore and create annotations on any piece of text from the mundane (song lyrics, poems, novels) to the unexpected (lists of all the deaths on Game of Thrones, restaurant menus, etc.). Read Lin-Manuel Miranda’s own notes about Hamilton and listen to the songs as you decipher the lyrics. Study William Shakespeare’s Romeo and Juliet line by line while watching videos of the play. Contribute your own annotations to the site or discuss pieces with people all over the world.

All of this can also be found at the Genius website, but the app offers more features. Hold your phone up to music and the lyrics will appear on your screen. Genius can identify the music in your iTunes so you can get the scoop on the tracks you love.
