Reference/Education app prototype

Hello, I am trying to build a reference/education app for iOS first then Android. This project will only be for iOS. This is just a prototype so I don't need any images or text, just place holders for when I add my own. Viewable in portrait and landscape Landing page Screen divided into 4 equal sections ready for images Button for "About" screen Button to "Begin/Resume" Main app Similar look to Flipbook and Windows phone (Windows 8) with tiles used for function and information. White background 3 rows x 4 columns First tile will occupy two columns. All other tiles will have a button. The button will mark the bottom of the tile complete with a date/time stamp. Each tile could have a image or color for the background with text overlay. 4th column does not have tiles Where 3rd tile would be at the bottom there will be Navigation at the bottom of 4th column: forward, back, save, main screen, and progress bar Area where first and second tile would be in 4th column is reserved for Infographics About screen Slide animation between screens This is just the prototype. I have features and information for another two versions beyond the prototype.
