I wish this notion of the "everything app" would die in the West. Yes, China has a highly successful everything app, but it exists because the government wants a centralized place to control digital activity. Such a model makes no sense in the west. We already have an everything app, it's called "App Store."
So many apps try to this strategy. For instance, Snapchat added games to the app. Why would I want to play a game in Snapchat when I have a nearly unlimited selection of games in the app store?
