Google has tons of apps on all its platforms but the Google app, a.k.a. the Google Search app, remains the gateway to most of its functionality. It does more than just search, of course, as it is also the app that houses Google Assistant. It is also your gateway to connected Google smart home devices. And by the time version 7.20 of the app rolls around, it will be able to do a lot more, including recognizing your own favorite pet name for Google Assistant.
