Messenger for MobileMessenger for Mobile was released on August 9, 2011 for iOS and Android, with an October 11 update making the app available for BlackBerry OS.
In December 2012, the Facebook Messenger app for Android in some regions (such as Australia, India, Indonesia, South Africa, and Venezuela) added the ability to use Messenger without a Facebook account by simply using a name and phone number. These changes are intended to allow Facebook Messenger to compete against similar mobile messaging platforms such as WhatsApp as an alternative to text messaging.[Later updates added the ability to use Facebook Messenger as a replacement text messaging client on Android, and added "Chat Heads", an overlay chat system originating from Facebook Home.
Messenger for DesktopMessenger for Windows Desktop was "officially" released on March 5, 2012 for Windows 7 users. Testing on the software began among a limited beta tester group on November 21, 2011; however, a leaked link to the beta-stage software was publicly revealed to tech bloggers by Israeli blog TechIT.Facebook responded the same day by announcing the link's availability through its Help Center.
Among its features is a "ticker" similar in function to the sidebar of friend activity seen by Facebook website users. At the time of release, "chatting with multiple friends, video calling, limiting chat availability and editing settings" were not available through the software. A Mac OS X version was mentioned by Facebook developers as forthcoming.
