As you can see in the screenshot, the app offers a clean layout similar to the OSX app with a similar full-screen experience. And like the OSX app, Pocket for Chrome ties into your existing Pocket account so that you any articles or video you save with another Pocket app or bookmarklet can then be viewed in the Chrome app.
