GameChanger Baseball ScoringPlatform: iOS and Android Price: Free or $7.99 a month/$39.99 a year for premium access. So 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 and helps out newbies with tutorials and touchscreen scoring. You can also make your scoring public so friends online can compare or 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.
