I apologize if this has been done in the past (didn't see it after a quick scan) but I was curious: What's your favorite app on your mobile device? For me, it's Twitter. I love Twitter and have grown a decent following thanks to a hockey blog I run. I thoroughly enjoy the fact I can check in on news, sports and basic happenings with one click. Twitter typically has breaking news quicker than other media outlets so it just makes sense that I'd check there first. If I'm ever bored I'll check out the Twitter app and engage with some like-minded individuals that I follow. That's mine - what's yours?
