A free app for Android, by Praveen Yuva.
This is a free educational application that will teach you about the US states. There are three different quizzes that you can take. The first one is about the capital, the second one is about the population, and the last one is about the states themselves.
Each quiz contains multiple-choice questions. There are different ways to learn, such as by reading the text or by listening to the audio.
If you get a wrong answer, you can use the hint to help you get to the right answer.
You can take the quiz in English, Spanish, or Portuguese.
The application is completely free.
