The name of Rap Genius' first mobile app -- Genius -- may signal the company's continued move away from only covering rap music and toward its stated quest to annotate all of culture. With Genius, which launched in late January, users can dissect the latest State of the Union as well as their favorite Kendrick Lamar song. Similar to the website, the app has a broad, searchable catalog of user-annotated lyrics as well as poetry and news verticals. The home page displays the top 15-20 items in each category and has a search function fixed at the top.
