Very Good Calendar Sync - All calendars. In sync.

Keep your calendars perfectly synchronised. Automatically and privately. Set up once and forget it. The app monitors your calendars and syncs changes in the background. New meeting on your work calendar? It appears on your personal calendar automatically. Syncs any calendar available in macOS Calendar.app. You control exactly what gets synchronised: Choose specific weekdays (skip weekends, sync only workdays), set daily hours (e.g. 9 AM to 6 PM only), set a start date for synchronisation, etc. You also decide what to share: all event details or only the time you're busy? Your calendar data never leaves your Mac. No credentials to share. No third-party access. No cloud storage. The app uses your Mac's native calendar access. Nothing is transmitted externally. Perfect for consultants managing client calendars, employees balancing work and personal schedules, freelancers juggling multiple projects, or anyone tired of calendar chaos.
