QuizUp iphone software (free)

QuizUp pits you against international trivia enthusiasts – and your facebook friends – in fast paced, multiple – choice games centered on an impressive range of topics including General Knowledge, Name the Flag, Word Definitions, History, and many more. The app tracks how many games you win in a category to better match you with you opponents, and though you can pay to level up faster with in-app purchases, they are never pushed in your face. There’s no single-player mode and an Internet connection is required, but QuizUp is a wonderful social quiz game.
