The free calendar that finally got me to switch

I was a die-hard Google Calendar user. Then Notion (the company) acquired Cron and rebuilt it as Notion Calendar. I tried it on a whim. Six months later, I haven’t opened Google Calendar once.

What changed

The “killer feature” of Notion Calendar isn’t any single thing — it’s the sum of small things:

• Two-way Google sync — edits in either app appear in the other within seconds
• Keyboard shortcuts — N for new event, T for today, J/K for next/prev day — match Gmail, Linear, and every other modern productivity app
• Notion AI integration — daily brief in the morning, meeting prep notes pulled from past meetings
• Multi-calendar overlay — see work, personal, and shared calendars in one view, color-coded
• Free — no tier gating the core features

The Google Calendar I’m replacing is essentially the same product it was in 2018. Notion Calendar is what Google Calendar should have evolved into.

The honest complaints

1. Slow initial sync. When I connected my 6 Google Calendars, the initial sync took ~20 minutes. After that, instant. But for the first hour, events lagged.

2. No CalDAV. This means third-party calendar apps (Fantastical on iOS, Thunderbird) can’t connect to Notion Calendar’s events. You’re locked into the Notion Calendar app. For me, fine — the iOS app is solid. But a real limitation.

3. Mobile app. The macOS app is excellent. The iOS app is good. The Android app is “fine.” None of them are best-in-class — Fantastical on iOS still wins the mobile crown.

Who should switch

Switch if:

• You’re already using Notion for docs, wikis, or projects
• You use multiple Google calendars and want better overlay UX
• You want free meeting prep / daily brief AI features
• Keyboard shortcuts matter to you

Stay with Google Calendar if:

• You use Fantastical, BusyCal, or another CalDAV app
• You’re in Outlook / Microsoft 365 (Notion Calendar syncs with those but Microsoft users tend to prefer Outlook)
• You need the absolute simplest possible interface

The free-vs-paid picture

Notion Calendar is genuinely free for everything you’d actually use. The Notion AI features are included if you have any Notion paid plan — but the calendar itself is free regardless.

Compare to:

• Fantastical: $5/mo (iOS/Mac), $10/yr (Android)
• Google Calendar: free but Microsoft 365 integration is paid
• Calendly for scheduling: $8-16/mo

For free, Notion Calendar is the best deal in this space.

Verdict

Notion Calendar is the calendar app Google should have built. It’s free, fast, integrated with the Notion ecosystem, and respects power-user keyboard shortcuts.

I’m not switching back.
