It's no secret that one of my favorite iPhone apps is Major League Baseball's At Bat [iTunes link]. Last season it provided real-time statistics and video clips from games across the league. This season, it added live video streaming of full games as well as Game Day audio. At first the video streams were free, then MLB switched the model to feature one free game of the day, and the others were available to MLB.TV subscribers.
Frankly I thought that was a bummer, as I don't want to pay a monthly fee for baseball. They must have read my mind, because version 1.4 was released this week with in-app purchasing. Users can buy any live video stream for $0.99US. Hooray! No more MLB.TV.
I've gushed over this app before, so I'll keep it short this time. Not only is it a great experience for fans, the developers seem on top of what we want. Each update is significantly better than the last.
Now if only the NFL and the PGA would create something as good.
