iScore has posted they have submitted iOS7 updates to App store for iScore but some have asked will the current version run on iOS7 while waiting on apple to approve.

Ok, I have downloaded iOS7 on my iPhone 4S and tried iScore Baseball v4.15 and all OK,
(ie v4.1.5 was the most up to date version before iOS7 release )

I have not done much more than a couple plays and looked up a few stats but I can say the existing version of iScore Baseball runs on my iPhone 4s with iOS 7

UPDATE
found couple minor bugs, (using .. iOS7, iPhone4S, iScore 4.15)
1- Date Picker on the game Info screen is not working properly
2 - Email gamecast link on game info screen

I saw the football and basketball apps in the app store, but haven't seen baseball yet. Has that been submitted?

I believe iScore submitted iOS7 updates for all their iScore sport apps, but as of this morning, there is not a new Baseball update in the app store. (my guess is apple is swamped). but the current version works ok with iOS7.

the current version for isCore Baseball for iOS is v4.15 release jul 19, 2013.

I am using the universal v4.15 on an iPhone 4S and have found only TWO minor bugs that do not impact the ability to score games on the iPhone .. (both on game info screen: date picker, and email iscorecast link)

I am confident iScore will have an updated version out there soon, but in the mean time I am not worried and can score just fine .

Updated iOS version 4.2 w iOS7 support now available in app store ..fixes these minor bugs
