Solution: We knew that there would be a significant amount of iteration so we created a solid yet flexible framework that would allow the user to watch a video then feedback consent (or not). As this was to be a proof of concept we also built a readable private repository for the app to report back to. The app it self was built in HTML and published in a controlled way so that we could iterate ideas to the client. We used PhoneGap to wrap this into a native iOS app which was then distributed to various registered test devices via TestFlight.
