I find it highly annoying that the dev's weren't ready for iOS 8. It seems like the ones heavy in the Apple system were first, but barely.
The developers had plenty of time with the ios 8 betas that they should have been ready for ios 8... And a great deal of them were. However, like I said above, apple gave them almost no time to get ready for the new iPhones. Its apple's fault that all the apps are stretched.
