YouTube's mobile app updated with support for navigating gestures, iPhones get it first
The new horizontal swiping gesture will allow iPhone users to move forward and backward through the videos. YouTube also mentions that swiping forward will take users to the next recommended video, whereas in order to go to the last video watched, they will only have to swipe back.
Unfortunately, as mentioned earlier, support for gestures will only be available to iOS users initially. YouTube hasn't said a thing about Android yet, but we're hoping the update will make it to Google's platform in the not so distant future as well.
