Tweetbot (iPhone and iPod touch)
It makes sense that the iOS-exclusive app most recommended by my Twitter followers was a Twitter app. There are tons of Twitter apps for iOS and other platforms, but Tweetbot is the cream of the crop thanks to its clean, intuitive interface and plethora of useful features. It supports multiple accounts—a must for me—while its customizable bottom bar lets you choose the options you use most. You can pick the various, link-shortening, image- and video-uploading, and read-it-later services you prefer, too. Tweetbot's custom sounds and smart gestures also help make this mobile Twitter experience truly unique.
