Which Facebook product was released in 2008 as a mobile application for iPhone users?

Facebook released Facebook for iPhone in 2008 as its dedicated application for Apple’s iPhone. The app gave users mobile access to core Facebook functions, including viewing updates, posting, messaging, and browsing profiles.

The launch came during the early growth of smartphone applications. Facebook had already been accessible through mobile websites and other phone interfaces, but a native iPhone application could use the device’s touch interface more directly and provide a smoother experience.

Facebook’s mobile strategy later expanded across many operating systems and hardware types. The company also separated messaging from the main Facebook application in many markets, leading to the widespread use of Facebook Messenger as a distinct app.

Facebook for iPhone is sometimes confused with Facebook Home, a 2013 Android software layer, or Facebook Lite, a reduced-data application introduced for users with slower connections. The 2008 iPhone release refers specifically to Facebook’s native Apple mobile app.
