Built to sync calendars quietly.
Not replace them.
Calendar FreeSync is a focused calendar sync tool that keeps Google Calendar and Outlook availability aligned so people who live across more than one calendar can avoid double bookings.
The short version
A background sync layer for busy people.
Calendar FreeSync connects supported calendars through official OAuth flows, lets users choose how events should sync, and runs in the background. It is a sync layer, not a replacement for Google Calendar or Outlook.
At a glance
Calendar sync without the extra scheduling suite.
Product category
Calendar sync software for Google Calendar and Microsoft Outlook
Primary audience
Freelancers, consultants, and people managing multiple calendars
Supported providers
Google Calendar and Microsoft Outlook / Microsoft 365

Apple iCloud Calendar is not supported yet
Sync, not another calendar
Calendar FreeSync works in the background so users can keep using Google Calendar and Outlook directly.
Availability stays private
Events can sync as protected busy blocks, which helps prevent double bookings without exposing every detail.
Focused setup
The product avoids scheduling links and round-robin booking so setup stays clear.
How it works
Focused by design, clear about what it does not do.
Calendar FreeSync is intentionally narrow. It keeps supported calendars aligned and avoids becoming another place to manage your schedule.
Who is it built for?
Calendar FreeSync is built for freelancers, consultants, and multi-calendar users who need availability to stay accurate across personal, work, and client calendars.
How is calendar access handled?
Calendar FreeSync uses Google and Microsoft authorization flows. Users do not share calendar passwords with Calendar FreeSync, and access can be revoked through provider account settings.
What does it not do?
Calendar FreeSync does not provide scheduling links, round-robin booking, or iCloud Calendar support today. Pro plans include a unified calendar view of all connected accounts.
