Desktop Informant

The Best Calendar for macOS is more than just a calendar. Informant for macOS is a complete planner/organizer with Calendar, Tasks, Projects, Notes, and syncs with all of the Informant products via Informant Sync.

Your calendar and your tasks represent what you need to do and when you need to do it. Informant brings them both together in a single view for a better way of organizing your day, week, or month.
