Double booking
Two guests show up on the same day. Refunds, bad reviews, and hours lost managing the fallout.
Live calendar radar
Never lose a booking to a double booking again.
iCalSync merges your Airbnb, Booking.com, Vrbo, Google Calendar, Outlook and Zoom calendars into one master calendar, catches conflicts before they cost you a guest, and sends you a report every evening.

The cost of chaos
A poorly synced calendar always ends up costing you
Three platforms, three calendars, one apartment — and the risk of accepting the same date twice.
Clashing meetings
A Zoom call scheduled during a check-in, or two client meetings at the same time because no one has the full picture.
Manual updates
Copy-pasting dates from one platform to another, every day, hoping nothing slips through.
Under the hood
A dashboard that speaks in signals, not spreadsheets
Green: everything's synced. Red: a conflict was caught. Nothing else to watch.
Automatic sync
Every 5 minutes, automatically — no manual work.
Conflict detection
Overlaps and double bookings caught the moment they sync, before a guest ever finds out.
Nightly report
Tomorrow's arrivals, departures and meetings, summarized in one email at 10pm.
Visual calendar
Day, week, month or agenda view, filterable by source, color-coded by platform.
Universal iCal export
One master calendar link to republish anywhere an iCal feed is accepted.
Full history
Every sync, every conflict, every notification, kept and searchable.

Frequently asked
Everything people ask before getting started
How do I sync my Airbnb calendar with Booking.com?
Paste each platform's iCal export link into iCalSync. Every calendar is imported, merged, and exported as one master calendar you republish on each platform.
Does iCalSync work with Google Calendar and Outlook?
Yes. Paste the iCal link of your Google Calendar or Outlook calendar (Teams meetings included). Zoom meetings show up through the calendar they are added to.
How often are calendars synced?
iCalSync checks every connected calendar every 5 minutes and re-runs double-booking detection on every update. Airbnb, Booking.com and Vrbo then refresh on their own schedule (often every 1 to 3 hours).
Can I cancel anytime?
Yes. Cancel from your account in one click: you keep everything until the end of the year already paid.
Is my booking data secure?
Traffic runs over HTTPS, your export links are secret, and you stay in full control of which sources are connected to each calendar.
Your next double booking will never happen.
Connect your first calendar in under 5 minutes. No credit card required.
