These are the applications I can't live without. OK, I could live without them, but I would be a lot less fun to be around.
TeamStream: Full disclosure—you are reading this article on Bleacher Report. I know, shocking. However, there is no app that I use more on my phone or tablet than TeamStream. The notifications, in my experience, are at least a few minutes quicker than those offered by similar applications.
Also, it's nice to know the second you can send that troll text to that Dallas Cowboys fan in your life.
MLB At-Bat: A must for any MLB geek. If you want just the baseline free version, you will get scores and updates like you want. Pony up for the subscription service and get immersed in baseball throughout the season with radio coverage.
MLB Full Count: While we are on MLB, I might as well toss out this free app, which delivers highlights and analysis throughout the season. It's not a bad way to waste a few minutes during the summer.
ESPN SportsCenter: I actually enjoy the overhauled look. It's more than scores, and it's easy to fly between sports to get the latest standings and schedules. If you want a clean and polished way to find out when your favorite team is playing, this is it.
Yahoo! Sports Fantasy: This is a biased pick for me, simply because the fantasy teams I do have on the site I enjoy more because of Yahoo!'s interface. It's easy to find available players and fix my lineup. Other sites have their advantages, but this particular app feels comfortable. (Thoughts on your favorite fantasy app?)
NBA Game Time: Pretty much the same idea as MLB At-Bat. If you want it free, you are going to brave some ads, though.
NFL Mobile: Rinse, repeat but with football.
Again, this is just a short list of ones I enjoy. Feel free to toss your own thoughts down in that little community pot o' suggestions below.
