Calendar apps have their own syncing service?

I don't like Cozi Family Organizer or Informat 5 calendars though. Looking for something else that is why I am asking.

No I do not want to use Google Calendar.

I want it to work on Android and iOS too.

Yes I know I will have to likely pay. That is fine.

I’ve never used the calendar myself, so not sure if it fits your needs. Nextcloud is pretty easy to set up though. Costs nothing if you self host.
