App doesn't work – PhotoArtista - Oil Review

I've deleted this app and reinstalled it and it's been no help. This app doesn't work. Perhaps it's an issue with the upgrade to ios 7. The app will open but nothing else. I'm greeted by a blank screen with menu options I can't select and except for a close icon box. I tap on it and that allows me to tap on the open photo button but the only result of that is to revert to the close button icon. Simply, the app doesn't appear to work at all at present.
