When you first launch the app, you'll see your home feed, which displays all the recent videos from the people you follow. Below each post, you can add a comment, like the video, or revine it (repost it to your account).
In the Activity tab, you'll see all of your notifications that appear when someone likes your videos or follows you.
In the Explore tab, you can see some of the top videos created in Vine. The app organizes videos into Channels, so you can browse through videos by specific category, like Comedy, Cats, or Food. There are links at the top for the most popular videos and those that are gaining attention.
Record a Vine
From any tab in the app, you simply touch the camera button at the bottom of the screen to get to the camera. Then touch anywhere on the screen to start recording. The icons at the bottom give you advanced recording options, such as tapping to focus on a subject and displaying a grid to keep your video level.
When you're finished recording, you can add a caption and post your video to Vine, Facebook, and Twitter.
The far-right tab in the app is dedicated to your Profile, which displays your bio at the top. In my case, it's my Twitter bio.
If you scroll past your bio, you'll see a stream of the videos you've published on Vine and a stream of videos you've liked.
