iPhone photo app

I have a database of 500+ photos, with info in excel file, including: - image name - image tags (search function to be based on this field) - Category Name - Notes (to be displayed when picture selected) I need an app that: with bottom tabbed bar (with icons and text) - Categories - Favourites - Search - About Categories Tab: - Display Tray of icons (similar to iphone home screen, slight variation to look and feel, graphics provided) - can scroll if categories exceed screen size. - after category touched, then loads photos in category, similar to camera roll thumbnail view - if thumbnail touched, then loads full screen picture with "notes" mentioned above. Favourites - Displays favourites in current "camera roll" thumbnail view - if thumbnail touched, then loads full screen picture with "notes" mentioned above. Search - like iphone search screen (search bar on top, search result thumbnails display immediately below while typing) - if thumbnail touched, then loads full screen picture with "notes" mentioned above. About - link to a webpage, - textbox to display some company info. I also NEED to be able to add AND remove pics and picture tags, notes to and from this database.
