Notion is an incredibly popular note-taking and project management service and now launching a standalone calendar service. At its core, Notion Calendar is a free next-gen version of Cron with a built-in, Calendly-like scheduling tool and a deep but optional Notion integration. It’s available for Mac, Windows, iOS and on the web. An Android app is also in the works. While Notion has long had a calendar view for its workspaces, that was always disconnected from the likes of Google Calendar, which is also the first outside calendar that Notion Calendar is integrating with (with others to come later).
