It is an Augmented Reality app, so as soon as the app starts you can see a fullscreen camera view that potentially displays the virtual content over the real environment.
What we ask you to do is simply to add five blank views to the app, making a very rough tabbed application, so that when the app starts the first view is displayed, and when the user goes to the fifth one he finds a simple central button that launches the augmented reality experience (that is nothing else but the camera view just explained).
Here you can find a simple scheme of what we mean: https://dl.dropboxusercontent.com/u/24450981/app_scheme.jpg
The application should be compatible with iOS 7 and delivered in .xcodeproj format with all the relative folders intact.
If we're happy with the result a future collaboration will be evaluated.
Thank you in advance for your availability.
