Sync your calendars in minutes.
Then let it run.
Calendar FreeSync connects your Google and Outlook calendars with real-time, webhook-based sync. No complex dashboards. No learning curve. Just three steps.
The app works as a sync layer: connect a source calendar, choose filters, connect a target calendar, and let Calendar FreeSync keep supported calendars aligned.
Setup flow
Three steps and you are done.
Connect your source calendar
Sign in with your Google or Microsoft account and pick the calendar you want to sync events from. Calendar FreeSync uses official OAuth, so your credentials never touch our servers.
Set your filters
Choose which events to sync by keyword or title. Only the events you care about get copied across, while everything else stays put.
Connect your target and let it run
Pick the destination calendar and you are done. From that point on, Calendar FreeSync automatically syncs events in real time using webhooks.
Why Calendar FreeSync
Built for reliability, designed for simplicity.
Real-time webhook sync
Events sync the moment they are created, updated, or deleted. No waiting for a polling interval.
One-way or two-way
Choose one-way when one calendar is your source of truth, or two-way for full bi-directional sync.
No duplicate events
Calendar FreeSync tracks every synced event to prevent duplicates from appearing on your calendar.
Keyword filters
Only sync the events you care about. Filter by title keywords so personal and work stay separate.
Automatic catch-up
If a connection drops, Calendar FreeSync catches up on missed events the moment it reconnects.
Secure OAuth
Your calendar credentials never touch our servers. We use official Google and Microsoft OAuth flows.
