Dinner, practice, a catch-up call. Drop a link in the thread, they tap a time — booked in ten seconds. No accounts, no “how about Tuesday?”
Never what you're doing, or with whom.
Connecting your calendar grants read-only free/busy access. Titles, guests, and locations never leave your calendar, and you can disconnect with one tap.
One link works for four people too. Connected calendars answer automatically, everyone else taps once, and the moment the last person's in — it books itself.
