I just posted my app, SportsIQ, and I think sports fans will love it.
SportsIQ is Android’s best and most comprehensive sports trivia game to date. SportsIQ has over 1000 unique questions that span 11 categories, 4 different question types, and 3 difficulty ratings.
You can also compete with friends via SportIQs Facebook and Twitter integration features.
