World Capitals is an Android application developed by Nuno Luís. It is a free education and reference program designed to improve your knowledge about world capitals and basic world geography easily. With this app, you can learn the capitals of each country in the world and see the country location on the map. The app also allows you to test your knowledge with the quiz on world capitals.

One of the most impressive features of this app is that it includes all 196 world capitals and the data is available in eight languages: English, German, Spanish, Portuguese, French, Dutch, Polish and Russian. Additionally, the information is available offline, which makes it convenient for users who don't have access to the internet. The app also provides an image with the country's location in the world, which is sourced from 'The World Factbook' by CIA. Moreover, users can filter the country list by continent, which makes it easier to focus on specific regions.
