Knotd is a book app for people who start non-fiction books and never finish them. Each title is a short audio summary you can finish in about 15 minutes, plus one-screen ways to make the ideas stick: swipe true or myth, choose your line in a story, spot where a case goes wrong, or watch a book's big lines handwritten in front of you. 850+ sets across 250+ books, quizzes with the reason behind every answer, and hand-picked paths. Free on iPhone.
