Some calendars you can see but can't reshape: a subscribed work schedule, a read-only team calendar, an account that isn't yours. cal-mirror copies one into a calendar you control, so you can reshare it, recolor it, or just see it next to everything else. It copies one direction only — your original is never touched — and it all happens on your Mac and iPhone. No account, no server, no tracking. Because the copy lives in your own calendar, your devices sync it wherever that account already goes. • Copy any calendar into any other — as many pairs as you like • One direction, always; hand-added events in the copy are left alone • Repeating events, all-day events, and moved appointments come across correctly • Nothing to log into, nothing collected • Menu-bar app on Mac; a simple list on iPhone and iPad
