This app is about a snake touching an apple, when the user gets tired just need to reset and start again.
Very interesting app, from which I learned a lot how to test people, by asking them question about different questions about history. The user read the question and answer it, if is right the Correct! label will come out and if is wrong the Try it again! label will come out, If the user don’t know the answer he can just press the Next button and go to the other question.
