Apple Calendar (iCloud Calendar) integration is currently on our roadmap and will be implemented as soon as possible.
We are actively working on adding native Apple Calendar support. This feature is a high priority for our team.
In the meantime, you have a few options to work with Apple Calendar:
Subscribe to your CalendarPA calendar feed in Apple Calendar (read-only)
Use Google Calendar as a bridge - sync Google Calendar with Apple Calendar
Manually add bookings to Apple Calendar from confirmation emails
We'll announce Apple Calendar integration as soon as it's available. Follow our updates or check back soon!
