AgatongFlags is a free app designed for nothing more than learning the flag of each country. Its target audience is those learning about different flags or curious about the basics of world geography; and while the app is not flashy or attractive, users that are in need of this type of app are unlikely to care.
AgatongFlags is a fairly no-nonsense app with one purpose: to teach the flags of each country. They are split up by continent, and although the app erroneously places Mexico in South America, it is otherwise error-free. You click on a continent, and you see an image-based list of flags for that continent. You can then scroll to see other flags as needed, all of which are in alphabetical order. If you click on a flag, you receive some very basic information on the country, including the location (on a small map), population, language, and currency. The app, itself, has no other features. The interface then is bare bones but functional and doesn't get in the way of the basic learning tools included with the app.
There is nothing inherently wrong with AgatongFlags other than an unattractive color-coding screen and the aforementioned Mexico error. However, the functionality of the app is very limited and will appeal to only a very small subsection of people; and for many it may be easier to just search the Web to look up just a few countries' flags.
Agatong Flags provides following information: each continent, country's flag, name of the capital city, territory size (area), population, official language, currency (monetary unit), and geographic location. Agatong Flags will automatically detect language, based on device-specific settings.
