Knowa: Did You Know? Quiz Live

Did you know frozen water takes up 9% more space? That's why ice floats. That's Knowa in a nutshell: amazing facts, turned into a game. Every day, the app picks three surprising topics for you, based on your tastes, across eleven themes. A topic is seven questions, three choices each, about three minutes. And after every question, a real explanation tells you the why behind the fact. Not a dry "correct!", but a little story you'll want to retell at dinner. We built Knowa because trivia apps were driving us crazy: ads everywhere, rote questions, never an explanation. You'd score points and learn nothing. So we did the opposite: a smart quiz with explanations, where every question can be reasoned out. No ads. No timer. No lives. Three topics, and the day is done. Knowa is made for a few minutes a day, not for hours on your screen. The best part is almost invisible: questions you miss come back a few days later, right when your memory was about to let them go. Call it microlearning or spaced repetition. Either way, that's how things stick. A progress map shows your general knowledge growing, theme by theme: history, geography, science, arts, philosophy… You pick your favorite themes, and every day we slip in one discovery. A taste of the catalog: • Counting to a million takes 12 days. To a billion: 32 years. • Birds fly in a V to save energy, each one riding the swirl of the bird ahead. So whether you came looking for history trivia, a geography quiz, a science quiz, daily facts, fun facts, or your fact of the day, you'll find the same thing here: three amazing stories a day, free, in English and French. You'll learn something new every day without even trying. Test your general knowledge. Better yet, grow it. And come back tomorrow. We're saving three more stories for you.
