Transfer iOS 7 apps to iOS 5?

I'm wondering if I can move Stardom: Hollywood from the iPad 2 to iPad/iPhone 4 and save the progress. I spent a fair bit of money into it and I don't want to lose it.

It all depends if the games use gamecentre. If they do just go ahead and download the app from the appstore on your new device but make sure you use the same game centre account. You should have your saved data. If however, the game/games do not use game centre then unfortunetely you can't transfer your progress. Hope this helps.

Not all apps run on iOS 5, most are developed for 6 and later.
