[AC Question]

im trying to understand what some of the apps are for on my boost kyocera android phone

That's a way for web pages to be opened without opening a full web browser. For example - I browser news articles on the Google Now feed (swipe left to right until I can't anymore on my Nexus 6P on the Google launcher), I decide I want to read an article I see so I tap it and it opens in the Android System Web View rather than opening Chrome.

This appears to be one aspect of the app..
