For TNW, an international blog for technology news, business and culture, we were asked to build the accompanying iPhone app. And we did.
The app provides a customizable home screen that lets you select the channels, editions and regional blogs, just like the main website. It's build for the latest iOS version (4.x) and supports multitasking. It has tight integration with several API's including Twitter, Facebook and Instapaper. All data is retrieved through a special interface which we created that hooks right into Wordpress, the CMS that powers The Next Web.
