Think you know everything there is to know about U. S. presidents? Prove it.

The Presidential Trivia Pop Quiz will exercise your brain by testing your knowledge of every American president, from Washington to Obama.

The app contains over three hundred trivia questions, covering diverse subjects like "Who was the tallest president", "Who was president during the Russian Missile Crisis", and lots more! Users are presented with a random piece of trivia or president, and asked to match up with one of three choices.

The Review mode lets you take a leisurely approach to answering questions -- with audible and visual feedback, and the opportunity to try again until you get the correct answer. The Quiz mode puts you up against the clock, in 1-, 2-, or 5-minute challenges designed to see how many questions you can answer correctly, before time runs out.
