I'm sure there has been a topic on this before, but I wanted to get an updated one going since I am fairly new to the iPhone 5 and iOS in general. What is your favorite app and why? Mine is the TuneIn Radio Pro app. I believe it was $0.99. It's my favorite app because I can listen to an AM Sports Talk station out of Cleveland while living over 2 hours away. The only negative is that it's a battery killer, but I always have my charger with me at work, which is when I use it the most. Probably my 2nd favorite is Zynga Poker, followed by Twitter.
