TeamViewer has been around at the App Store since 2010, when its first iOS app allowed users to remotely pilot a PC or Mac.

Twitter-owned Vine was updated today on Android, bringing it closer to parity with the social media company’s recently updated iOS app. You’ll now have new camera tools, the ability to “revine” a post (similar to re-tweeting), access new Channels, and a brand new Capture Widget.

The new widget is designed to get you faster access to your Vine recording ability, shaving precious seconds off your launch of the Vine app.
