Nerdish is a learning app that helps you grow your general knowledge. The articles inside are our own — written to show you things you'd never thought to look up, feed your curiosity, and help you learn more about the world. You can read them or listen to them, and most take about ten minutes: why people like spicy food, what Nefertiti actually looked like, how the internet crosses oceans. What's inside: - Articles we write ourselves. Each one starts with a question our editors find interesting, and gets researched properly before it's written. - Topics from the life around you. Sleep, coffee, déjà vu, the internet, Nefertiti — things you pass by every day without wondering about them. - Our own writing framework. It keeps every article interesting and concise, but still genuinely educational — a lot of thought went into getting all three at once. - Built as microlearning for adults. Short chapters of a couple of minutes each, designed to fit a phone screen and a busy day. - Audio for everything. Read it, listen to it, or follow the text while it plays. - Historical photographs, archive material and artwork alongside the text, with facts and details in the margins. - A wide range of subjects, from the human body to ancient history — and the connections between them. We built Nerdish for people who: - would rather spend phone time on something better than socials. Same ten minutes, different outcome. - enjoy learning random things for no particular reason. Curiosity doesn't need a goal attached to it. - want to stay mentally sharp. Reading something unfamiliar is a small habit that keeps the mind working. - want to find their way back to reading. Short pieces are easier to start with than a book you've been meaning to open for months. - want to have more to say — about art, history, or why the sky is blue. Why it works: There's no way to measure general knowledge and no point where you have enough. But it's what you're using when you read the news, or decide whether something sounds true, or find a solution that came from somewhere unrelated. Hardly any of us sets out to work on our knowledge. Nobody ever taught us how — there's no course in general knowledge, nowhere obvious to begin. So it stays on the list of things you'd like to do. Nerdish works because the mechanism is already there. Curiosity is what built your general knowledge in the first place, and it doesn't need much — an interesting question and ten minutes. And knowledge doesn't stay in separate piles. We write science with its history in it, history with its culture, and culture with the people behind it — nothing is only about one thing. Pick a topic, read or listen, learn something you'd never thought to look up. That's how general knowledge grows. Learn with us about: - Health and the human body: sleep, memory, ageing, and how the body actually works. - History: ancient empires, revolutions, great discoveries, and the people who changed things. - Science and technology: space, evolution, physics, AI, inventions, and everyday phenomena explained properly. - Daily things: why déjà vu happens, how coffee was discovered, where common ideas come from. - Art and culture: painting, music, architecture, design, literature, and the movements behind them. - Food: where dishes come from and why we like what we like. - Famous people: the lives behind the names.

One challenge a day. That is the whole ask. Arena is not a study app. It is how you find out whether your studying worked. Every answer earns XP toward your level, and every topic you play becomes a skill with its own tier, so over time you build a profile of what you actually know. The way a game shows a character's stats, except the character is you. HOW A CHALLENGE WORKS A card shows a category, a topic, and how hard the question is. Double-tap to open it: usually four options, one guess, no hints. Then you see the correct answer, a short explanation, the XP it earned, and the ideas your answer moved. IT ADAPTS TO YOU The feed picks what to show you next from how you have been doing, drawing on every level from beginner to specialist. Questions you answer come back later on an FSRS schedule, the same spaced-repetition algorithm Anki uses, timed to just before you would have forgotten them. EVERY TOPIC, ITS OWN TIER Questions come from 22 categories: Life Sciences, Physical Sciences, Medicine and Health, Mathematics, Technology, Engineering, History, Geography, Law and Government, Business and Economics, Psychology and Social Sciences, Philosophy and Religion, Language and Linguistics, Literature, Arts, Film and TV, Music, Gaming, Sports, Food and Drink, Lifestyle and Culture, General Knowledge. Inside them, each topic you play is a skill with a tier from Bronze to Diamond. It rises as you answer well and can slip when you miss or let it fade. Strength in one topic does not cover for weakness in another. GUILDS Create a guild, share the code, and everyone who joins gets a private leaderboard that compares streaks, levels and skill tiers. FREE, AND MEMBERSHIP Arena is free, with a daily limit on challenges. Membership removes the daily limit and gives you a permanent member number based on when you joined. USD 5.99 per month or USD 39.99 per year. It renews automatically until you cancel, and you can cancel anytime in your store's subscription settings.
