SYNCDATE
5.0 out of 5 stars
(1 Rating)
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.
