A flexible calendar for demanding Mac schedules
BusyCal is a macOS calendar and task manager that replaces Apple Calendar for users who need deeper control over views, alarms, filters, and multi-account sync.
Views and workflow on Mac
Day, Week, Month, Year, and List views can be tuned for density, fonts, colors, and which panels appear. Calendar Sets let you switch between work, personal, and shared calendars in one click, while Smart Filters save complex searches and layout presets for quick recall.
- Integrated tasks appear on due dates and carry forward until completed.
- Natural-language input speeds up creating events with locations, attendees, and alarms.
- A menu bar companion shows a mini-calendar and upcoming items even when the main window is closed.
Sync, privacy, and accounts
BusyCal connects to iCloud, Google, Microsoft 365, Exchange, CalDAV, Reminders, Todoist, and more, so one Mac app can host calendars from several services. A free edition covers basic needs; premium features unlock after purchase or subscription, with a 14-day trial on the Mac App Store build.
Time blocking and alerts
Travel-time planning, weather, tags, sticky notes, and conference-call detection help you manage real-world scheduling. BusyCal also ships its own alarm window with snooze controls that work even when the main app is not running.
BusyCal 2026.2.3
Version 2026.2.3 requires macOS 11.5 or later and adds automatic cross-calendar time blocking with synced rules across Mac and iPhone, plus scripting hooks and alarm-window improvements documented in the official release notes.
