After the Google Assistant for iOS was already in the US in May, it was only a matter of time before Google’s “Ok, Google” -AI also on our devices. Of course you can not call the app “Ok, Google”, which is a big disadvantage is, but as long times it has opened only once, too. Going
calls, messages, reminders, calendars, music, etc. everything works quite easily, but Of course, there are sometimes restrictions, so that you still have to intervene. Who, however, occasionally wants to communicate with Google via voice, because you use the Google search anyway, for which it should nevertheless be tempting.
Whether you want to use it instead of Siri (or even Alexa), of course depends entirely on your own preferences, but to see beyond the box is actually never wrong.
