This is the real Relay flow, playable. Pick a moment, then you answer each request by tapping the glowing item on the keyboard. No typing. That's the whole point.
The most-asked question in your chats, answered in one tap. On iPhone and Mac (Windows calendar availability is coming in the next Microsoft Store update), Relay reads your busy times from the calendars you connect, Google and Outlook, and types your actual free slots into any conversation. On iPhone you choose which calendars count. On Mac it reads the main calendar of each account you connect. Busy professional, or a PT, coach or tutor running your whole week out of Google Calendar: your diary just learned to answer for itself.
