1 iPhone app and 1 Android app

I am looking to have 1 iphone app and 1 android app created. These are text based apps (just conversation starters) They will display questions to ask other people in the room. I will need in app purchases on both to allow the users to purchase additional questions. 1) Users will select a category 2) Users will then see questions (1 question per page) based on the category they choose 3) Users will have the option to purchase additional questions through in-app purchase if they choose to after they get through all of the initial questions, otherwise they will be able to select a new category. Admin Panel: We need the ability to add new categories and new questions to the application. We want the app to have adds at the bottom of the screen. I already have the graphics for all of the questions made so I just need everything put in app form.
