Explore all 195 countries of the world and hear them in their own languages. Myatlastic is a world atlas you can listen to. Spin a 3D globe covered in flags, pick any country, and take a spoken tour led by a natural, human-sounding voice in the country's own language, with a small English translation as it plays. It's made for curious kids, families, students and travellers. LISTEN TO THE WORLD • Play the tour: a 2–3 minute spoken visit to every country, in the local language, with English translation. • Photos of the places being described change as the story unfolds. • Phrasebook: pick a phrase such as hello, thank you or how much? and hear it said by a local voice. A LIVING 3D GLOBE • A photorealistic Earth that keeps turning, with every country's flag on it. • Tap a country to fly to it. When a tour starts, its flag rises from the globe while the rest of the world fades to grey. • A soft background sound while you explore, which you can switch off at any time. EVERY COUNTRY AT A GLANCE • Flag, capital, currency, languages, local time, culture, history and food for all 195 countries. • Compare countries side by side, convert currencies and practise spelling country names. • Mystery Country: follow the clues and guess where you are. PASSPORTS OF THE WORLD • See the real passport cover of every country. • Every visit earns an immigration-style entry stamp. The more you explore, the fuller your passport gets. QUIZ & PUZZLE • Quiz: flags, capitals and world facts, such as how many continents there are or how many countries speak Spanish, each with a short explanation. • Puzzle: drag each country's name onto its flag.

Verdict
The clearest difference is update cadence: Myatlastic at every 3 days against Duoler's every 3 months. Myatlastic also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.1). On price, ads and in-app purchases there is nothing between them.
