Does BusyCal support syncing with other apps, such as Omnifocus and 2Do?

BusyCal has built-in support for CalDAV and WebDAV servers & subscriptions, and by extension supports any third party app that supports the same.

Some other apps, such as Omnifocus (see this article here), allow publishing their events as a WebDAV subscription. You can simply add such subscriptions to BusyCal.

Other apps such as 2Do, a popular Task Manager on macOS, iOS and Android, are also well supported. 2Do supports syncing via CalDAV. You can, for example, use both 2Do and BusyCal via iCloud. You can learn more about 2Do here.
