Exploring the world with atlas is now easier, The app gives you information on continents, countries, satellite and map views of the continents.
App Features:
• Information on continents
- rank, area, population
• List of all countries
• Information about countries
- sub-region, capital, area, population, latitude and longitude, currency, languages and more
• Google satellite and map views
• Material design
For that, I'd just use Google. Why use a separate app? List of countries is also incomplete.
