Quiz your friends on the history of the United States of America by sending them questions via Messages. Just open the app, select a question and send it to your friend who will have 10 seconds to answer it.

Be nasty - the recipients will not have a chance to quickly browse the Internet searching for the facts they do not know and they will see the result only if they send you their response.

You can either create your own questions or use questions which are shipped with the app.

A perfect tool for practicing before exams or just for your pleasure.
