Their calendar plugin provides CalDAV, so you could just use your local calendar app that syncs with the server over that protocol.

Have you tried to combine that with caldav?

I use and like CalendarBridge because it can also sync multiple calendars.https://calendarbridge.com/

I use reclaim.ai to do the calendar sync. It works pretty well, worth a look.

Google Apps/Calendar but no CalDAV for those of us who left the google mothership takes away a big reason I'd use this.

Aren't there any apps that offer CalDAV and CardDAV synchronization?

Will sign up in a heartbeat as soon as you have CardDAV / CalDAV support!

Looks promising! Does it have mobile apps or even better, support for standard protocols like CalDAV or Etesync?

Would love to see calendar sync for MS exchange supported :)

What do you need in a calendar service that you can't find elsewhere?I use the Calendar app with NextCloud[0] for a CalDAV server + calendar web interface. It's fully-featured as far as I can tell. I use its CalDAV functionality to sync to my Android phone using DAVx^5[1], which integrates the calendars natively so that you can use whatever calendar app you want on your phone (I use Etar[2]).[0] <a href="https://apps.nextcloud.com/apps/calendar" rel="nofollow"
