If you run more than one calendar, you already know the double-booking trap. Your work calendar shows a meeting. Your personal calendar shows that same hour wide open. You say yes to lunch, and now you’ve promised to be in two places at once.

The latest version of Fantastical goes after exactly this problem. The new feature is called calendar mirroring. You set up rules, and Fantastical automatically copies events from one calendar onto another so each one knows what the other is doing.

The hard part isn’t the copying. It’s privacy. You don’t want your personal calendar spilling its details into your work account, and you don’t want a client seeing the name of your dentist appointment. Fantastical gives you control over what gets mirrored and how much of it shows up. You can block the time without exposing what’s in it.

I made a video for the Flexibits team that walks through the whole thing, from setting up your first rule to keeping the details private.

Calendar mirroring shipped in this week’s Fantastical update. The same release adds a Meet With feature for checking other people’s schedules in your organization, plus the usual batch of fixes. You can grab the update on the Fantastical page.

Fantastical has been solving everyday calendar headaches like this for 15 years now. This one fixes a problem I’ve actually lived. I’m glad it’s here.
