Get to know the whole world, one quiz at a time. Explore countries, capitals, flags, regions and cities through engaging quizzes. Discover the world from Amman in Jordan to Quito in Ecuador. Learn at your own pace and build your geography knowledge a little at a time. Just a few spare minutes on the train, while waiting or between appointments are enough to learn something new. “My new favorite pastime. So much better than endlessly scrolling through social media.” “The best geography app I’ve tried. You discover new places and learn where they are as you go.” ▶ Start right away Open the app and jump straight into a quiz. No registration. No ads. ▶ Quiz your way Choose from multiple choice, typing, saying it out loud, or tapping the globe. Pick the quiz mode that works best for you. Flag quizzes offer even more variety: name the country, pick the flag, point to the country on the globe, or color the flag. Would you like to focus on a specific region of the world? Customize the quizzes to match the topics that interest you most. ▶ Daily Quiz Practice regularly with the Daily Quiz – every day, a new selection of questions awaits you. The app automatically adapts the questions based on your answers: questions you answer incorrectly appear more often, while topics you’ve mastered appear less often. ▶ Multiplayer Quiz Challenge your friends and family to play a quiz together. Pick a topic, share the code, and compete in a live quiz. Who knows the world’s capitals best? And who can really name all the countries in Asia? ▶ A Wide Variety of Quizzes More than 35 quiz topics. Start with countries, flags and capitals across every continent, plus regional deep dives — think U.S. states, Swiss cantons, Italian regions and cities from London to Amsterdam. Every region has free quizzes waiting for you. ▶ World Atlas Explore the interactive globe. Discover each country through photos, fun facts, and carefully curated information. More information, travel guides and the latest headlines are just a tap away. Not sure how to say Ouagadougou or Reykjavík? You can listen to the pronunciation of the country and capital names. ▶ Did you know? Open the app each day and you'll find a new country fact waiting. You can also add the flag widget to your Home Screen to discover new flags throughout the day. ▶ Become a supporter geotrainer is an indie app, made and maintained by one person.
