Snapchat Launches Update for iOS with New 'Snapchat Stories' Feature
Snapchat Stories add Snaps together to create a narrative. When you add a Snap to your Story it lives for 24 hours before it disappears, making room for the new. Your Story always plays forward, because it makes sense to share moments in the order you experience them.
Your Story never ends and it’s always changing. The end of your Story today is the beginning of your Story tomorrow. And each Snap in your Story includes a list of everyone who views it.
Snapchat is a free download on the App Store for the iPhone. [Direct Link]
