According to a message being displayed on the app, which was only available for iOS, it will no longer be supported as of July 29th. "We know that Paper really resonated with you -- the people who used it," reads the farewell message on Paper, "so we've tried to take the best aspects of it and incorporate them into the main Facebook app."

In other words, thank you for using it, but it's time to go back to the real Facebook app.
