Viki
Wikipedia is one of the most amazing things on the Internet. Viki makes it even better. This slick app wraps the world's collaborative encyclopedia in a delicious wrapper of well considered typefaces and intuitive interfaces. It also gives you quick access to articles about things nearby, lets you bookmark frequently read articles, and uses VLC integration to display the wide range of media formats used by the site. And thanks to slick, native code, it scales from the Watch to the iPad Pro gracefully.
