Why people pick SyncThemCalendars
Pay for sync, not for a scheduling suite
If you already use Calendly, Cal.com or your provider's own booking pages - or simply don't need them - a bundle makes you pay for features you'll never open. We charge for the one thing you came for.
Unlimited calendars on every plan
Add a new client account or a family calendar without changing tiers. Our plans scale by the number of syncs you run, never by how many calendars you connect.
Set-and-forget reliability
Changes on Google and Outlook are pushed to us by the providers, so copies update in moments - not on a polling schedule. Thousands of professionals leave it running for years.
When OneCal might fit you better
If you want booking pages and a unified calendar view bundled with your sync tool in a single subscription, OneCal is a polished all-in-one product and the bundle may be worth it for you. If sync is the job, a dedicated tool does it for less.
Switching takes minutes
Start your free trial
14 days, no credit card. Connect your Google, Outlook or Apple iCloud accounts in your browser.
Recreate your syncs
Pick each source and target calendar, choose one-way or two-way, and set your privacy options. About 2 minutes per sync.
Turn off the old tool
Once you see events flowing, pause or cancel your previous tool so the two don't copy the same events side by side.
Frequently asked questions
Can SyncThemCalendars replace OneCal for calendar syncing?
Yes. One-way and two-way syncs across Google, Outlook / Microsoft 365 and Apple iCloud, with per-field privacy controls and unlimited events - the syncing core is fully covered.
How is the pricing model different?
OneCal prices by connected calendars and per user. SyncThemCalendars prices by the number of syncs (from $3.99/month billed yearly for 5 syncs) and every plan includes unlimited calendars and events.
Does SyncThemCalendars offer booking links?
No, and that's deliberate - we do calendar sync only. It pairs perfectly with whichever scheduling tool you already use, because those tools see your true availability once your calendars are in sync.
Ready for calendar sync that just works?
Set up your first sync in 2 minutes. Google, Outlook and Apple iCloud, one-way or two-way, with your privacy protected.
