About this app
Corto puts your geography knowledge on the clock. A place appears. Tap where it is on the world map, as fast and as accurately as you can. Every question scores up to 1,000 points: 800 for accuracy, 200 for speed. Ten questions, 10,000 possible. Getting close takes real knowledge of the world. Every place you get right lights up your globe. Countries turn green as you find their places, and your places raise your level. Spin the globe, tap a country and play the quizzes about it. Start free with World Cities and ten learning quizzes, then unlock 166 themed quizzes: capitals and cities, flags and airport codes, volcanoes, stadiums, world wonders, remote islands. Or unlock all of them at once, including every quiz added later. Every quiz is a lifetime purchase. Buy it once and it is yours, restorable on any device you sign in with. Corto has no subscriptions and no ads. Think you're quick? Challenge a friend head-to-head. Trade turns, match their score, and settle it on the map. They don't need to own the quiz: your copy covers the whole match. A new Daily every day: five places, one try. Plus a weekly set of three quizzes. Your best scores go to the Game Center leaderboards:
