From people who stopped double booking
Real calendars, real relief.
Preventing double bookings for 350+ busy professionals
Work, consulting, family: three calendars, connected in under two minutes. I haven’t double-booked since.
Bryan Ramirez
Director of Client Services
I’d paid for less reliable apps. The free plan keeps my calendars aligned in the background and does everything I need.
Nelson Santana
CEO of Private Startup
Work, school, personal: I connected all three calendars in minutes. Now I forget the sync is even running.

Who it's for
Built for people who live across more than one calendar
Calendar FreeSync keeps Google Calendar, Microsoft Outlook, and iCloud Calendar availability aligned automatically in the background. Pro adds a unified calendar and booking pages for Google and Microsoft calendars.
Personal meets work
Keep personal and work calendars separate but perfectly in sync, so colleagues won’t accidentally book you during personal time.
No double bookings
Events from one calendar appear as busy blocks across all your others. Conflicts become impossible before they can happen.
Pro feature
Every calendar. One view.
The unified calendar brings all your connected Google Calendar, Microsoft Outlook, and iCloud Calendar accounts together in a single month, week, or day view. Each account gets its own color, and the busy blocks your syncs create are hidden automatically, so every event appears exactly once.
