Nowyouknow introduced Codiqa which looks pretty sweet as it doesn't restrict you to a small subset of functionality and fixed structure, but it is limited to producing web prototypes.
Alternatively, Blueprint (https://blueprint.io) lets designers build their native iOS apps directly, with a similar interface to Illustrator or Codiqa.
Blueprint differs from such limited-structure services in that you get very fine-grained control over the design & functionality of your app. Designers deserve better than a list of checkboxes of what should be in their app!
