Vine (s twtr) has become a popular medium for users to share six-second videos, but until now there hasn't been a way to know how popular individual Vines are. On Tuesday, the company introduced "loop counts," which are available now in the Vine update for iOS (s aapl) and Android (s goog). Loop counts are exactly that -- a number in the corner of a Vine that shows how many times a video has been "looped" -- or played end-to-end and restarted -- since April 3. The update, which includes a redesign, also offers richer analytics for Vines, including milestones like reaching 100 "likes."
