The original Twitter app for iPhone has undergone an extreme makeover. Iconfactory has launched Twitterrific 5 (US$2.99 for a limited time, $5.99 regular price) on the App Store, ushering in a comprehensive interface overhaul that I've become absolutely smitten with since I started using the app a few days ago.
As a longtime Tweetbot aficionado, Twitterrific's design overhaul was initially a bit shocking in its simplicity. The default timeline view places an emphasis on the text of tweets, displaying them in larger-than-average type with wide-line spacing on a solid background. The result is clean, clutter-free and easy on the eyes.
What really makes Twitterrific stand out, however, is the ease with which you can customize its already lovely aesthetic. Using a dedicated appearance panel, you can select from five different fonts (Helvetica, Proxima Nova, Signika, Museo Slab and Calluna), increase and decrease the font size, resize or remove avatars, change line spacing and toggle between a light and dark theme. This panel also has its own brightness slider independent of the device's. Overall, there's a high degree of customization. What's more, you can have Twitterrific automatically switch to the dark theme during nighttime hours, which has ended up being even nicer than it sounds.
The interface is smooth and fast, with secondary screens such as the built-in browser and image viewer sliding into and out of view quickly and moving between screens is lightning fast, even on my iPhone 4. Followers and followed users are presented in a unique grid view of their names and avatars, which is a nice touch, especially if you're like me and associate the people you follow mostly with their pictures.
