Integration with scheduling tools
When choosing a calendar app, integration with scheduling tools is worth checking. Support for the iCal format and the CalDAV protocol determines how wide the integration options are.
Its API is extensive and supported by many scheduling tools. It allows secure integration through OAuth 2.0 and also supports automatic detection of free time.
It works well in Microsoft 365 environments. Integration with Teams allows meeting URLs to be generated automatically. For company use, it has the advantage of being easier to administer.
It is easy to use within the Apple ecosystem, but integration with third-party tools is limited. The iCloud Calendar sharing feature is aimed at families and small teams.

Strategies for using multiple calendars
In practice, there is no need to settle on one app. A practical approach is to take advantage of iCal compatibility and subscribe to the other calendars from your main one. For example, if you use Outlook for work and Google Calendar for personal life and sync them via iCal, scheduling tools can see your combined free time.
In hybrid work environments, merging the office-day calendar with personal calendars becomes especially important. The choice of calendar app affects how easy scheduling is for the whole team.
