Atlas teaches you where every country in the world is — on a real map, at your own pace, completely offline. Tap where you think a country is and Atlas tells you exactly how close you were: "Peru is about 640 km to the southeast of where you tapped." No right-or-wrong buzzer, no lives, no timers — just a precise, calm way to build a map of the world in your head. FIVE WAYS TO PLAY • World — find countries on the map. Atlas tracks how well you know each one and brings back the ones you're still learning. • Continents — find any country on the continent named. • Capitals — find capital cities on the map. • Flags — see a flag, find its country on the map. • Practice — play freely without affecting your progress. DAILY FIVE Five countries a day, the same five for everyone. Nothing to keep up with — just a reason to open the map. YOUR PROGRESS Collections shows every country with its mastery level. Statistics shows your precision over time, your best answer and how much of the world you've mastered. FREE AND ATLAS COMPLETE Atlas is free to download.
