Der Entwickler hat geantwortet:

FaceDialer is currently not on sale due some issues in iOS 7.
Apple broke some things in iOS 7 (to be precise JavaScript in WebClips). We and other developers already reported these issues back in July. Unfortunately they didn't get fixed for the release. We hope that Apple addresses these issues in iOS 7.1 or in an earlier bugfix. Currently there is no way to make FaceDialer run on iOS 7. It will be back in the AppStore as soon as apple fixes those bugs.

Hmmm... Bei mir funktioniert diese ohne Probleme - ich schreib Ihm nochmal. Auf jeden Fall kommt diese App wieder zurück, sobald alles an iOS 7 angepasst wurde. Man hofft auf einen schnellen Fix.
