Recipes Spinner Mobile App

Hello my name is Gianluca and I'm a graphic designer. A client contacted me because he wants me to design an App. about recipes and food coocked in a healthy way. An App wich works like: [login to view URL] [login to view URL] The App will be designed for iPhone (first) and then also for iPad with a new design. I will do the design. The App will not have all the features that are showed in that one, specially for the Pro version, but I'd like to know how much should cost the development of such an App, and eventually remove all the functions wich makes its cost high. For sure the client wants the spinner effect, then there will be a list of recipes and the recipe explained in detail. Look how the Apps posted above work, and make me a quotation. Rating system not necessary, unless is very cheap and easy to realize, neither the chance to comment. The search function will increase its cost very much? I need to know a price range to discuss with the client. Thanks
