Quick answer: CalendarBridge and SYNCDATE both offer calendar synchronization. Choose using your actual accounts, directions, privacy settings and plan limits. CalendarBridge combines sync with scheduling features; SYNCDATE offers a permanent Free plan for a small arrangement. Neither a calendar-count headline nor an advertised speed establishes that your setup will fit.
Compare the arrangement before the price
CalendarBridge's individual pricing, checked October 6, 2026, lists Basic, Premium and Pro for 2, 5 and 8 synced calendars. Annual billing is $4, $8 and $32 per month; monthly billing is $5, $10 and $40. The page includes booking pages and an AI Executive Assistant. Calendar-view limits and sync-connection limits are separate; verify the tier for the arrangement you want.
SYNCDATE's current pricing distinguishes connected accounts, total calendars participating in syncs and calendars in one sync:
| Arrangement limit | Free | Plus | Pro |
|---|---|---|---|
| Connected accounts | 2 | 5 | 20 |
| Total participating calendars | 2 | 20 | 100 |
| Calendars in one Mirror | 2 | 4 | 5 |
| Calendars in one Push | 2 | 10 | 20 |
| Future event window | 30 days | 1 year | Unlimited |
Five calendars in one Mirror need Pro even though Plus has a 20-calendar total allowance. The total allowance does not mean every calendar can mirror every other calendar. Use the three-account Mirror recipe or client-to-hub Push recipe to check direction and fit, then compare costs in the same currency and billing period.
When each option is useful
Consider CalendarBridge if its sync, calendar view and scheduling features match your needs. Check its current provider and account support rather than assuming all tiers or calendar types behave identically. Its advertised speeds are vendor claims, not our comparative timing test.
Consider SYNCDATE if a supported copying arrangement is your main job, or its Free limits cover it. For Google and Outlook, provider notifications can prompt updates; retries, provider throttling and other conditions affect delivery. We have not run a head-to-head speed benchmark, so speed alone is not a sound verdict.
If you only need to see calendars together, a native combined view may be enough. The Google–Outlook method guide separates viewing, Outlook's native personal availability option, subscriptions and copies. For two Microsoft identities, use the Outlook setup guide.
Review privacy for the chosen setup
Do not assume that SYNCDATE always copies masked Busy titles. The personal-to-work recipe starts with masked titles and omitted descriptions, locations and guests. The Google–Outlook two-way recipe starts with original titles, descriptions and locations enabled, with guests and reminders off. Review the preset before creating either arrangement.
A title of Busy and an event's Free/Busy status are different settings. Inspect the destination and the scheduling view you rely on. If destinations need different appearance settings, check the asymmetric recipe and its Pro requirement. Compare the other service's documented settings rather than treating an unverified privacy default as a competitive weakness.
Switch without running two writers on the same calendars
Do not run the old tool and a replacement on the same production calendar pair for a day. Two independent tools can each treat the other tool's copies as new source events. SYNCDATE's handling of its own copies is not a promise that it recognizes another service's copies.
- Record your source calendars, destinations, directions, filters and date window. Review which original calendars own each commitment and which entries are copies.
- If possible, test the replacement using separate empty calendars and harmless events, with no guests. Confirm permitted write access and review the title, description, location and availability settings before starting. Creating a sync can also copy existing eligible events.
- Read the old service's current disconnect instructions. Confirm whether stopping or deleting a connection removes its copies or leaves them behind. Plan any cleanup before touching production calendars; do not delete original commitments or assume a cancellation cleans up copies.
- Stop the old service from writing to the production pair before enabling the replacement on that pair. Inspect the remaining calendars and resolve old copies according to the vendor's instructions. If ownership is unclear, ask support before bulk cleanup.
- Enable the replacement, then create, move and delete a harmless original event in each direction you need. Inspect the actual destination calendar, including its Free/Busy status. Check the scheduling or booking view you depend on before retiring the old service.
The aim is a verified handover. Timing and copy cleanup vary by provider and service; there is no universal zero-gap switch procedure. If your organization requires administrator approval, use the workspace access guide and get that approval rather than changing direction to bypass it.
Make the decision with a small verified setup
Write down the accounts, number of calendars in each arrangement, direction, fields allowed to cross and future window. Choose the smallest plan that fits; a paid plan is useful when a real limit or capability requires it. Verify before expanding. If Free covers the job, keep using Free.
For other options, see the calendar sync tool comparison. For a Google or Microsoft pair, continue to a concrete setup rather than starting with a generic signup.
Frequently asked questions
Should I run CalendarBridge and a replacement together?
Avoid running two independent copying tools on the same production calendar pair. Test on separate calendars, check the old service's cleanup instructions, then stop its writes before enabling the replacement. Verify copies and availability before expanding.
Is a larger plan always necessary?
No. Start with the actual account, arrangement and future-window limits. Native options or a small free setup can meet the job. Verify the chosen setup before expanding.
