Show HN: Minimalist HN reader with material design

Hello everyone!, this is a app I have being working on recently. I know there are number of HN readers on android. But couldn't find a one suitable for daily use. So I started developing this app. News articles, comments open in default browser of the device. Click on title of the item to open the article and anywhere else to open comments. Pull down to refresh. Swipe left and right to change the tabs. This is only the first phase of application. Lot of functions yet to be implement (you can read more in Google play listing). Before developing further I would love to have some feedback. BTW I'm a CS undergraduate.Thank you.
