You can't start a call directly from Meet yet—but you can schedule a video call in Google Calendar, and join it from Meet. You'll see a list of your upcoming meetings as in the top screenshot on this article.
Tap the correct meeting, then join the video call much as you would for a standard Hangouts video.
Google Meet worked well in our tests—much the same as traditional Hangouts.
Its only problem is is the same: It drains your battery and kicks in your laptop's fans on longer calls.
Its text chat is basic, much like the older IM-style Google Talk app, but Hangouts' high-quality videos with 25 participants more than made up for that.
There might be only one real criteria for the best chat app for your team: How easy it is for everyone to use.
With dozens of great video and text chat apps for teams–each of which include quite similar features–the deciding factor is often down to the way your team works.
Recently, Google split text chat off into a brand new app that has more in common with Slack than IM, along with a redesigned version of of their video chat. It's much the same as Hangouts—in fact, it appears to be using the very same backend service, just on a different domain and with a refreshed UI. You'll book appointments first in Google Calendar, then open meet.and jump on the call when it's time.
For the most part, Meet is the same as Hangouts' video calls—only with a fresh new design focused just on video chat.
This year, Google is doubling down on its success with Hangouts, splitting it into two apps for businesses: Meet and Chat.
