Munin is a microlearning app for curious adults who want to build their general knowledge. Learn something new every day with short lessons in history, science, philosophy, psychology and mythology, then keep it with spaced repetition quizzes that bring each fact back right before you would forget it. STOP SCROLLING, START LEARNING You already spend time on your phone every day. Munin turns that time into knowledge. Every lesson takes a few minutes, states its learning goal up front and ends with a short quiz. Same quick hit as a feed, except you finish smarter. LESSONS THAT STICK Most learning apps let you read and forget. Munin does not. Every question you answer joins your personal review queue. Get it right and it comes back later. Get it wrong and it comes back sooner. This is spaced repetition, the memory technique used by medical students and language learners, built into every topic. TYPE IT, DON'T TAP IT Recognising the right option in a list is easy. Recalling it is what makes it stick. Selected questions ask you to type the answer, and questions you already know well switch to typed answers in review. Small typos are forgiven and the official spelling is shown. WHAT YOU GET • Bite-sized lessons written for adults, with the learning goal stated before you start • Quiz questions with explanations: multiple choice, typed answers, ranking, fill-in-the-blank and matching • Spaced repetition review: one daily review session sized to what is actually due • Your knowledge map: every topic you study becomes a tile on a growing hex map • Streaks, XP and ranks: build a daily learning habit one day at a time • Trophy shelf: master a topic and it goes on display • Weekly forecast: see what is due today and what is coming up this week • A growing library: new topics and lessons are added regularly WHAT YOU CAN LEARN • History: ancient empires, revolutions, trade routes and the world wars • Philosophy and ideas: Stoicism, existentialism, Buddhism, logic and the Enlightenment • Mythology and culture: Greek, Norse and Egyptian gods, the Renaissance and architecture • Science: the solar system, the human body, nuclear energy and the weather • Mind and behaviour: psychology and how memory works • Economics and power: propaganda, economic crises and the legacies of empire Pick the topics you care about and Munin builds your daily plan around them: general knowledge with depth, a few minutes at a time. WHO MUNIN IS FOR • Anyone who wants to replace doomscrolling with a daily learning habit • General knowledge and trivia fans who want depth, not just facts • Students and lifelong learners who need a memory system that actually works • Commuters, queue-standers and coffee-break readers with a few spare minutes WHY "MUNIN"?
