AnkiDroid is good, too.
What obscure small country are you from? Well, I know its capital city, thanks to AnkiDroid.
Once I was chatting with an Uber driver who said that he was from "Africa" and expected my knowledge of Africa to end there.
Me: Where in Africa?
Driver: umm, west part.
Me: Let me guess. Ghana?
Driver: Next to Ghana.
Me: ok. Benin?
Driver: very close to Benin.
Me: Togo?
Driver: Ya!
Me: You from Lomé? [capital of Togo]
Driver: You know Lomé??!
All thanks to #AnkiDroid!
