BusyCal review

BusyCal is the calendar for people who want to shape every view. The vendor describes week views of 2 to 31 days, month views of 1 to 12 weeks, a year view that can work as a heat map of your busiest months, and a sortable list view with duration totals. Tasks sit directly on the calendar and carry forward until done, with sync to Apple Reminders, Google Tasks, Todoist and Microsoft To Do. Account support is the widest in this list: iCloud, Google Calendar, Microsoft 365, Outlook.com, Exchange, Yahoo, Fastmail and any CalDAV server, with push updates where supported. Meeting tools include availability checks on Google and Microsoft 365, join buttons for Zoom, Teams, Meet, Webex and GoTo, and a Bookings page. A menu bar app, color tags with time tracking and smart filters round it out. It is free for everyday calendaring with a 14-day trial of the full app; the cost of the depth is a busier interface.
