iOS 7 is compatible with all iOS 6 apps, I think. Make a back up before you download iOS 7, then download it. I swear, nothing has happened to my Battleship Craft, it is still the same, and all my ships were still there when I downloaded iOS 7. Just make a backup in case something goes wrong, and make sure you have good internet.
