SYNCDATE Verified Customer Reviews (2026)

What is SYNCDATE?

SYNCDATE keeps several calendars honest about when one person is busy. It is for anyone who holds a calendar at more than one organisation: a consultant with a calendar at every client, a fractional executive, an agency owner, or someone with a day job and a business on the side.

Connect each account over OAuth: Google Calendar, Microsoft Outlook or Microsoft 365, iCloud, Fastmail, Nextcloud or any CalDAV server. Choose which calendars feed which, one way or both ways. From then on, a meeting booked at one company blocks the time at the others. Subscribed iCal feeds can be used as a read-only source.

A copy says what you decide. By default a copy shows Busy and nothing else, except in a two-way sync between calendars you own, which keeps the real titles. You can write your own text for the title, description and location on every plan. The Plus plan adds if/otherwise rules that look at an event's length, start time, weekday or a guest's email domain. The Pro plan lets each calendar in one sync follow its own rule.

Google and Outlook changes usually reach the other calendar in under a minute. CalDAV calendars are checked about every 15 minutes. Every run shows on the dashboard. Delete a sync and it can remove every copy it made. Hosted in the EU, with a data processing agreement on every plan.

The free plan holds two calendars across two accounts with no card and no time limit. Plus and Pro add accounts, calendars, range and rules, with a 7-day trial. Team gives every seat the Pro plan on one invoice; the administrator sees plan status and sync health, never anyone's events. Hosted in the EU. The same account can be used from an AI assistant over MCP.
