The update for Android and iOS removes the Spring Training features, and sets up the app for the regular season. It also adds in universal access, so subscribers can use any platform they wish to get the advanced features. So, if you're one of those strange people that happens to have an BlackBerry Z10, a Google Nexus 7, and an Apple iPad, you can finally use the same account on all of them.
The Android version of the app got a couple of extras with re-designed individual team pages, and a new design for the news section. As always, it's $19.99 for the year subscription for the premium features, or $2.99 per month. If you want to grab MLB At Bat '13, it's available for free through the iTunes App Store, Google Play Store, and BlackBerry World.
