The document discusses mobile design trends for 2015 and similarities and differences between native iOS and Android apps. It covers five major design trends: storytelling, subtle color palettes, blurred backgrounds, parallax scrolling, and animated elements. There are some similarities between iOS and Android apps in information structure, basic UI elements, and list-based navigation, but also differences in UI, feature selection, list selection, back button usage, and global actions. Guidelines are provided for converting an iOS design to an Android equivalent, including menus, app bars, top navigation, navigation drawers, search, contextual action bars, alerts, action sheets, and common controls.
