As part of a recent hackathon, I developed a Trivia engine and iOS app. The engine scrapes web pages and APIs to automatically generate questions (I have several thousand already).

The iOS app just got in the app store Monday night. Response has been solid so far. We're giving away a hat to the top scoring player each day.

Would love any feedback on the app (it's free). Android is on the way.
