Today we're announcing Poke, an iPhone app that makes it fun and easy to say hello to friends wherever you are. The poke feature has been a part of Facebook since 2004. Now we're excited to share a new poke experience for mobile.
With the Poke app, you can poke or send a message, photo, or video to Facebook friends to share what you're up to in a lightweight way. You can poke an individual friend or several at once. Each message expires after a specific time you've set, either 1, 3, 5 or 10 seconds. When time runs out, the message disappears from the app.
To see a message from a friend, press and hold the message until it expires. If you ever see something you're uncomfortable with, you can click the gear menu and report it.
Poke will be available in the App Store
starting later today.
