Twitter recently released an update to mobile.twitter.com for feature phones and older browsers.

In a blog entry, Coleen Baik, designer at Twitter, detail how it meticulously overhauled mobile.twitter.com. "We completely overhauled this client from the ground up, a process that resulted in a lighter-weight, faster client that looks and feels like twitter.com and our mobile apps," posted Baik.

He said, the app was overdue for an update on many fronts and we took the opportunity to refresh it inside and out. "We had about nine weeks to design, prototype, develop, test, and calibrate mobile.twitter.com for launch. There were a handful of challenges we took on," wrote Baik.

"On the top level, we brought the user interface in line with the new version of Twitter that we launched back in December, so you can enjoy a consistent experience on any device. Under the hood, we completely overhauled the view layer for our RAILS backend, with new mustache templates and streamlined stylesheets," Baik wrote.

Here is the Twitter mobile Old vs. New:

Twitter Mobile : Old vs. New

Challenge include:

  • "support more than 13 different browsers on thousands of different devices, each with their own rendering idiosyncrasies
  • accommodate input methods with dissimilar requirements
  • build layouts with pre-CSS3/HTML5 standards
  • optimize for browsers with javascript turned off
  • scale gracefully from resolutions as small as 240 by 240 pixels all the way up to widescreen views on the desktop
  • minimize page sizes for slower networks
  • make it look and feel like Twitter, even without images.
  • pave the way for even more feature consistency with other twitter.com clients," Baik said.

All along the way, Twitter tested while building on an array of 300 devices. After more than two months of work, the mobile.twitter.com was rolled out with improvements and many positive responses. Improvements include:

  • "pages that were up to 63% smaller than those in the old mobile.twitter.com
  • sessions that were up to 37% smaller
  • 63% fewer requests in some views, like profile pages," Baik adds.
