The calendar that made time blocking beautiful

Cron started as an indie calendar app that prioritized design and speed above all else. It was so good that Notion acquired it in 2022, rebranding it as Notion Calendar while keeping the core experience intact. It syncs with Google Calendar and iCloud, adds a beautiful interface on top, and integrates deeply with Notion for task-to-calendar workflows.

Who it's for: Knowledge workers and Notion power users who want a beautiful, fast calendar that integrates with their workspace. Best for those who live in time blocks and need to see Notion tasks alongside calendar events.

The honest take

✓ What works

Best-in-class design and speed on desktop
Free — completely, no paywall on core features
Excellent multi-timezone support for distributed teams
Deep Notion integration if you're in the ecosystem
Keyboard-first navigation saves real time

✗ What doesn't

No native mobile app yet (iOS/Android still limited)
Requires Google Calendar or iCloud — can't standalone
No AI features for scheduling or meeting prep
Windows version still catching up to Mac
Notion acquisition means uncertain long-term roadmap

Verdict

Cron (now Notion Calendar) is the best-looking and fastest calendar app on desktop, and it's free. If you use Notion and Google Calendar, it's a no-brainer. The lack of a mature mobile app and AI features holds it back from being the complete package, but for desktop time-blockers, nothing is more pleasant to use.
