At long last, it’s finally arrived. Twitter launched Vine, its popular video-recording and sharing app, on Android as it passed 13 million registered users worldwide. It includes much of the same functionality as the iOS version, allowing users to shoot concise, six-second videos that loop automatically on playback and include sound from the handset’s built-in microphone. Recording and editing footage will feel remarkably familiar to anyone that’s experimented with the iPhone app; just tap-and-hold to record, before pressing again to start a new shot. Once the progress meter at the top of the screen is full, the clip is complete and the user is then free to share it on Vine, Facebook or Twitter. The general navigation on the Android version is also pretty similar to the original iOS app. The top of the screen is split into four tabs.
