AppSheet Calendar view is not very functional compared to Google Calendar or similar specialized calendar platforms.
It would be easy and great solution to have an iCal export of specific slice or view from AppSheet app. This would enable to use Google Calendar or any calendar to show app items.
Note:
An open standard file format originally introduced in 1998, iCal stores calendar information in a format that’s easily shared between applications, both calendar and apps such as Microsoft Excel. The major calendar applications support iCal’s ICS file format, including Microsoft Outlook for Office 365, Apple Calendar, Yahoo Calendar and Google Calendar.
P.S. I know that there is an option to use Google Calendar as a source in AppSheet, but it’s functionality is limited, and doesn’t solve the problem.
