If you haven’t already downloaded QuizUp for your iPhone you might want to start asking yourself why.

QuizUp is a trivia app that syncs to your social networks allowing you to challenge your friends (and strangers) in real-time quiz games.

...Plus it’s oh-so-much more than just a simple quiz game!

Here's 4 Reasons Why You Need to Download QuizUp

1. Endless Topics

QuizUp boasts over 280 topics to choose from including Chemistry, Quentin Tarantino, Beer, Name the Flag, Toronto Maple Leafs, and Winter Olympics. Topics are crowd-sourced by topic geeks: self-identified subject aficionados who have submitted questions to QuizUp for review. Do you routinely geek out? You just might be the perfect candidate to submit questions and answers to QuizUp.

   

2. Endless Opponents

With over 7 million users, you’ll never be without a match-up. Whether you’re duelling your Facebook friend on “The Hobbit” or challenging a stranger from Poland on “1990’s Music”, you’ll always have a long list of people to play against.

   

3. Meet New People

After hitting rematch six times, it seems only polite to add someone as your QuizUp friend.

Build up a roster of QuizUp friends and continue to challenge them on your common topics. Start a conversation and learn more about their life. Common questions to start with include:

  • “How did you become so knowledgeable about Buffy the Vampire Slayer?”
  • “Are you a real-life chemist?”
  • “How many hours of Skyrim play did it take to get you to Arch-Mage level Quiznerd?”

4. Improve your brain

Instead of wasting your life “crushing it” on Candy Crush, flex those brain muscles with quiz after quiz (after quiz...) of great information!

  • Did you know that...
  • Lithium is the lightest metal?
  • Urwaga is a Kenyan banana beer?
  • Cloves consist of 20% essential oils?

Level up your knowledge to impress your friends IRL (and spend some time in the Web Culture topic so you know that IRL means this not this. I’m looking at you Math Quiznerds).
