Blip for xkcd is a new app from the developer of Simple Weather. It's got material design, comic meta data (mouse over text), integration with explainxkcd.com, random comic view and more. Also it's open source, which always has my deepest respect.
I really like Blip. https://play.google.com/store/apps/details?id=com.tanmay.blip
