Well, I'm a bit late with this one, but my newest mobile app: Jury Duty, is now available as a free download from Apple's App Store. I know I had posted about it when it was released on the Android Marketplace, but I also wanted to let iOS users know they can grab it now too!
Jury Duty is a mobile poll app where you can answer political-based questions about the United States and high profile court cases. You can also see how your votes compare to others as the application tracks all votes and shows you the percentage of users that choose the same answer as you do! Check it out!
