Paid version · in development
Blink Calendar Sync early access
An event in any of your calendars shows as Busy in all the others, so nobody books you twice and nobody sees what the event is.
What the paid version does
- Busy everywhere, details nowhere. Your other calendars get a Busy block at the same time, with no title, attendees, or notes.
- Two-way across Google, Outlook, and iCloud. A client's Microsoft 365, your own Google Workspace, and your personal iCloud, in any mix.
- Automatic. Connect each calendar once. No .ics links to copy and no events to enter twice.

Questions
What does joining the early list cost?
Nothing. You leave your email address and get an email when Blink Calendar Sync opens.
Can't Google and Outlook do this on their own?
Partly. Free/busy sharing and published calendars work one way at a time, and a subscribed calendar refreshes on the provider's schedule, not when you change an event. The guide walks through each built-in option and what it shows.
How do other calendar sync tools compare?
