GameChanger Baseball Scoring
Platform: iOS and Android
Price: Free or $7.99 a month/$39.99 a year for premium access.
Even if you can't fill out a scorecard as well as the guy behind you with the golf pencil and reading glasses who's kept score in the same seat since before you were born, GameChanger doesn't care. It helps out newbies with tutorials and touchscreen scoring and can also make your scoring public so friends online can compare, to show folks at home how your kid's college team fared during a weekend tournament or what you're scoring that disputed call they're watching at home. For that extra $7.99 a month, subscribers get live play updates, game replay, in-game alerts and updated recap stories, stats and charts.
