iOS 7 will be available for download tomorrow. However, running the current version of ComicBookLover on iOS 7 will result in visual artifacts making it not possible to operate the app or read comics properly.
We recommend users thinking of upgrading to iOS 7 to wait until most of their favourite applications have been updated and operate correctly.
If you choose to stay with iOS 6, the current version of the app will be the last one for iOS 6. All future development will focus on iOS 7.
Today, Apple updated their app store so that you will still be able to download the iOS 6 version of the app, even if in future the only listed version in the App Store is for iOS 7. http://9to5mac.com/2013/09/17/ios-app-store-now-allows-legacy-app-downloads-to-support-older-hardware-and-software/
Since we now have access to the final release version of iOS 7 and the Xcode 5 development tools are out of beta, we hope to have an iOS 7 compatible version of ComicBookLover in the App Store within a few weeks. Thanks for your patience!
