Apple Pencil with icalendar

Hello 6229,

Thanks for visiting the Apple Support Communities. We understand wanting to use your Apple Pencil to write entries into the Calendar app.

As of now this feature is not available for the built-in Calendar app, but you can find third-party apps that offers this feature.

For more information, please check out this thread: Is there an Handwritten calendar App with notifcations for the iPad

Hope this helps. Kind regards. 

No.

Not with the native Calendar app, but there are third party “write-in calendar apps that will work with your Apple Pencil.

Search the iOS App Store for these.

Best of Luck to You!
