Local Calendar - Is there a way to subscribe to it?

We have Local Calendar now, which is great! Is there a way to add this calendar to programs like the iOS Calendar App, or Outlook, or anything like that?

The idea would be that I would make a calendar more accessible for non-techie users, who don't access HA from a desktop browser often but might want to be able to see/edit certain calendars (light settings, sprinkler timing, etc). I can't find much info about this anywhere; I assume it's not currently possible?
