Write an iPhone application -- 2

I want a much modernised look and feel, and it must look as though it was compiled narively for each device, I want to be able to exploit the native look and feel of IOS, Android and Windows The first level of the system must have the following items on screen 1. Application Name on top a. News b. Around Me c. Weather d. Things to Do e. Ward Councillors f. Emergency Contacts g. Municipal Contacts h. Tenders i. Online Forms j. Directions k. Tweets The menu system might span more than one screen The application must have an option to Login to protected applications At all times the look and feel of the respective device must be maintained. It must look as though it was built for that specific device. I understand Xamarin allows this.
