Twitter has announced native video support for Twitter Kit. Twitter users on iOS will be able to enjoy Twitter videos and GIFs without having to leave their app or launch the Twitter app.
Users of iOS devices can view full screen videos hosted on Twitter directly from the app. Any app running the latest version of Twitter Kit on iOS8+ will automatically support native video viewing.
Android users are yet to get any such update for their twitter apps but its likely twitter is working on such an app.
