Nov. 27 — Twitter Inc. Nov. 26 said it will start collecting lists of applications installed on users' mobile devices to help tailor the content, including marketing messages, it displays for members.

Although the feature could trigger user concerns over privacy, Twitter said people can opt out of the tracking by going into app settings for Apple Inc. iPhones and smartphones powered by Google Inc.'s Android software.

The feature, called “app graph,” will help provide more relevant advertising and improve suggestions on which accounts to follow, the San Francisco-based company said. Although app graph will help to pull in more messages and other content to timelines, it won't collect information from within the apps, Twitter said.

“To help build a more personal Twitter experience for you, we are collecting and occasionally updating the list of apps installed on your mobile device so we can deliver tailored content that you might be interested in,” the company said.

Twitter, under pressure from investors over concerns that user growth is slowing, is adding features to help it attract and keep new users. Twitter's monthly active user count rose 23 percent to 284 million in the third quarter.

Chief Executive Officer Dick Costolo replaced several top lieutenants in 2014, including ousting his chief operating officer and appointing a new chief financial officer and head of product.

In a Nov. 12 blog post, Twitter said it plans to roll out an instant timeline to let consumers see what's happening on the site without having to first follow people. The company is also working on new mobile applications, executives said, and will simplify the sign-up process and better organize content around geography and events.
