Connect Calio to the tools you already use
A scheduler is only useful once it knows when you are actually free. Connect your calendar and Calio automatically works around everything already in it — meetings, client work and personal appointments. New bookings appear in your calendar the same way.
Calio only sees when you are busy, never the title or the attendees of your appointments.
