SAN FRANCISCO (AP) — Facebook is ready to start broadcasting live video on its iPhone app.

The option to show live video is being turned on Thursday for everyone in the U.S. with Facebook’s app installed on an iPhone. The Menlo Park, California, company plans to extend the iPhone feature to all 1.6 billion of its worldwide users during the next few weeks.

The live video option is coming out after nearly two months of testing in the U.S.

The feature will enable Facebook users to share live video of their adventures and other more mundane activities with friends and family. It’s similar to the live video app called Periscope that Twitter introduced on its messaging service last year.

Facebook Inc. is still working on adding live video to its app for Android devices.
