Google has finally updated it's Play Newsstand App with Materiel Design UI, to be ready for the Android L launch this month. The Newsstand essentially combining Magazines and Google Currents in one app. The widgets has been updated too.
Newsstand is now using Material Design, which incorporates "larger images, more contextual headers, and smoother transitions" into the overall feel of the app. Users are also able to swipe horizontally between topics, as well as vertically to get more info on a particular topic.
Also new with this update is a better way to read magazines on phones. The experience has generally been fine on tablets , but definitely needed some work on the smaller screen. As of now, phones will get the option to pick and choose between articles, which will display in a much easier to read format more like that of the current News section of the app. Improved topic cards are now front and center, making it even easier to find content relevant to your interests.
