Filmstrip
What: arrange a top-level pages side by side, and let the user swipe them back and forth to view them one at a time
When: you have pages of content that are conceptually parallel, such as the weather in different cities or the scores in different sports
Why: each item to be displayed can occupy the entire screen; no space needs to be used for tabs or other navigation
How: a filmstrip is like a carousel for a mobile application’s main page
