Calendrz mirrors your availability across all your calendars automatically. When you're busy in one place, every other calendar knows it.
How it works
Calendrz works silently in the background. Set it up once, and your availability stays accurate everywhere — automatically.
Link all your Google Calendars in one place — work, personal, side projects, anything. No limits on how many you connect.
Whenever you have a busy event in any connected calendar, Calendrz detects it immediately — in real time.
Calendrz auto-blocks the same time slot across all your other calendars. Everyone sees you as busy. No double bookings, ever.
Why Calendrz
Most people juggle two, three, even four calendars daily. Calendrz was built for exactly that.
Not a sync. Not a copy. Calendrz creates lightweight blocker events in your other calendars the moment a busy event appears — so every scheduling tool sees accurate availability.
Core featureThe moment an event is marked busy, Calendrz acts. No delays, no manual triggers, no syncing windows. Your calendars are always up to date.
Real timeChoose which calendars mirror which. Block in one direction or all directions. Set working hours so personal time is never accidentally blocked during off-hours.
FlexibleCancel or move an event? Calendrz removes or updates the blockers everywhere, instantly. Your calendars never accumulate stale blocks.
