This article explores the ways in which designers use graphical elements and screen interactions to create iPhone-applications that are easy on the eyes and mind. The aim of this article is to display common trends and design approaches in iPhone app design – please notice that they are not necessarily optimal ones from the design or usability point of view.“…from smashingmagazine!

Facebook (iTunes Link)
In the new Facebook 3.0, you’ll find a grid layout that users can swipe left and right to access more categories. Because it mirrors Apple’s native UI, users do not have to “learn” how to use it all over again. A similar approach exists in Web design: users expect to see a logo in the top left, navigation along the top, etc. Facebook has taken this concept mobile, using large buttons that are easily distinguishable and tap-able.

Tweetdeck [iTunes link]
Tweetdeck is a good example of user interface design on many levels. Notice how the design highlights recent updates. The application could display the updates in a new window, with a categorized or tabbed list. But it doesn’t. Instead, a more familiar dialogue menu is displayed — it serves as a springboard to jump to a specific category or to clear the messages altogether.

Flickr [iTunes link]
Flickr is another example of how to achieve a good balance between functionality, visual design and the small display area on mobile devices. Think about it: what is at the core of Flickr? Photos. Its users probably do not want to look at big clunky navigational elements; instead, they are looking for pictures. Flickr has managed to fit all of its core functionality without heading down the highway to navigational hell. In fact, most elements in the navigation are handled by interacting with the photos themselves. Simple and smart.

Next Read [iTunes link]
The Next Read application allows friends to share books. Here all books about a particular topic are presented, including the title, cover image, review rating and number of people who have recommended it. Notice the padding and a lot of white space for each navigation option; this makes the areas easily clickable and easier to navigate.

myPantone [iTunes link]
Would we expect any less from Pantone? The color picker shown above is a layered interface that lets you pick from a range of colors, sort and scroll as well as open and close detail screens, all without too driving you crazy.

New York Times
Isn’t it great when applications just let you do whatever you want to do? For an app with as much information as the New York Times’, users are bound to have their favorite sections. Well, guess what? The New York Times cares: it lets you customize the tab bar’s navigation to include only your favorite sections of the paper. Drag an icon down the tab bar and you are set. The downside of the design is, of course, its lack of visual appeal.
