Facebook has released a new messaging app named Poke. An app that allows users to send messages and will disappear after up to 10 seconds. It looks like they are competing with Snapchat app that provided the same functionality. Currently, the Poke messaging app will allow messages to be sent between Facebook friends on iOS only. The messages can be expired after 1, 3, 5 or 10 seconds after being opened. The app also have a report feature to report unwanted messages. iOS users can download iTunes Store as of now.
