How to display your Apple iCalendar on the Invisible Display

You can share any iCloud calendar by generating an ICS link. Check out this iPhone User Guide and scroll down to "Share a read-only calendar with anyone".

With this link, you can then add the calendar to the E-Paper Calendar via the companion app.  

The URL of the ICS link is hard to guess, but there may be situations where this isn't as safe as a password-protected link. 

A native integration would require us to store an app-specific password that gives access to your calendar events. We are unsure if this would be  better or safer than the method outlined above. We welcome hearing your opinion on this via info@invisible-computers.com
