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 your calendar accounts, create a sync between any two of them, and let Calendar FreeSync keep them aligned. Pro users also get a unified view of every connected calendar.
Setup flow
Three steps and you are done.
Connect your calendars
Connect the calendars you manage on the Connectors page. Pick a color for each one to keep them organized. You will need at least two connected before moving on to step 2.
Create your sync
Assign a meaningful name to your sync (e.g., Personal -> Work). Then pick a source and a target calendar, and optionally add keyword filters so only the events you care about get synced across.
Let it run
That's it. Your sync runs automatically in real time based on the settings you chose. Need two-way sync? Create a second sync going in the opposite direction.
Every calendar. One view.
Once your accounts are connected, the unified calendar brings them all together in a single month, week, or day view. Each account keeps its own color, and the busy blocks your syncs create are hidden automatically, so every event appears exactly once.
Included with Pro and the 7-day free trial, with up to 10 connected accounts. See pricing

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.
Booking page
Pro plans include up to 5 customizable scheduling pages so clients can book time directly, with availability automatically protected by synced calendars.
Secure OAuth
Your calendar credentials never touch our servers. We use official Google and Microsoft OAuth flows.
