Twitter has launched a first-party version of
Vine, an app for the iPhone and iPod touch that it bought the rights to in 2012. The app is similar to ones like
glmps, letting users shoot small, looping videos that can be shared with others via a native social network. Vine posts can also be shared on Twitter and Facebook feeds, and any content linked in tweets can be opened inline on the web.
Vine Twitter posts link back to the
vine.co domain. Each clip also contains audio, although sound is off by default. The Vine app and service are free and support unlimited uploads. People shooting with the app must have an iPhone 3GS or better.
