Comparison

Zulu and Google Calendar.

Zulu isn’t a second calendar but another door to your Google calendar: a Mac app you drive with the keyboard, an iPhone app with a full week, and a service that maintains travel time and blockers. Everything you do in Zulu lands in Google. Everything you do in Google shows up in Zulu.

As of:

What stays in Google

Your events, calendars, sharing, and accounts. Zulu keeps no copy of its own that could drift apart; it reads through the Google Calendar API and writes back through it. Google stays the source of truth, including for things Zulu can’t do:

  • Creating recurring events and changing recurrence rules. Zulu shows series and edits single occurrences, “from this one on,” or the whole series, but doesn’t create new recurrences.
  • Reminders, tasks, appointment schedules, sharing calendars, email notifications.
  • Everything on Windows, Android, and in the browser. According to Google, Google Calendar is available in the browser and on Android, iPhone, and iPad; Google doesn’t offer a Mac app of its own.

What others see in Google

Everything Zulu creates is an ordinary Google event. A travel time is called “⏳ Wegzeit,” a blocker “Blockiert” (or whatever you name it) and is private. Anyone who sees your calendar in Google Calendar or Outlook sees that you’re on the road or busy, without needing Zulu. If you stop using Zulu, these events remain and can be deleted in Google.

How Zulu gets to your calendar

You connect each Google account once through Google sign-in (OAuth) with the permission for Google Calendar. The Zulu backend keeps a cache for 30 days back and 180 days ahead and receives changes from Google via push; as a safeguard it also polls every minute. You can revoke access in your Google account at any time. More under Your data.

Questions

Is Zulu a Google Calendar app for the Mac?

Yes, in the sense that it only shows and edits Google calendars. It needs the Zulu backend, which is connected to Google on your behalf.

Can I keep using Google Calendar?

Yes, in parallel and at any time. Both show the same data. You’ll still need Google Calendar for recurrences, reminders, and sharing.

Does it work with a Google Workspace account?

Yes, provided your organization allows access by apps. Working locations and out of office exist only where Google offers them.
