In Google Calendar, I can add a calendar a link to an iCal file. However, unlike calendars listed under "My calendars", this new calendar (listed under Other calendars) won't show up on other calendar apps with my Google Calendar, such as Windows 10 Calendar, or iOS Calendar, or Samsung Calendar. What I have to do then is add the subscribed .ics file to each and every one of those clients manually. Is there an alternative to Google Calendar that I can use that will sync these subscribed calendars to my calendar clients?
The price should ideally be less than $15 and not a subscription.
