The short version: Vimcal costs around $20/month and is built around speed and a dedicated team time-zone overlap view. Notion Calendar (formerly Cron) is free and tightly integrated with Notion's workspace, but has no dedicated overlap feature. They were genuine rivals before Notion's 2022 acquisition of Cron, and the comparison still holds today for anyone choosing between them.
Before it became Notion Calendar, Cron was an independent calendar app, and coverage of Notion's 2022 acquisition specifically named it as having competed against tools like Vimcal. That rivalry is worth knowing if you're choosing between the two today.
What happened to Cron
Cron built a following as a fast, well-designed calendar app in its own right before Notion acquired it in 2022 and rebuilt it into Notion Calendar, free, and wired directly into the rest of Notion's workspace. Independent editorial coverage of the deal specifically framed Cron as having competed for the same users as Vimcal, Morgen and Reclaim.ai, this wasn't a vague "same category" comparison, it was a named, direct rivalry at the time.
Pricing: the biggest practical difference
Notion Calendar is free. Vimcal costs around $20 a month. For most individuals, that alone settles a lot of the decision, unless Vimcal's specific features are worth the difference to you, in which case it's worth trying Notion Calendar first anyway, since it costs nothing to rule out.
Where Vimcal wins
Vimcal's "Time Travel" view for visualising a distributed team's overlapping hours is a real, built-out feature Notion Calendar doesn't match. Vimcal is also generally faster and more keyboard-driven, aimed at people (executive assistants, founders, recruiters) who live in their calendar constantly, with more scheduling-link and quick-booking features for people managing a high volume of external meetings.
Where Notion Calendar wins
If you already run your work through Notion, pages, databases, tasks, Notion Calendar's tight integration with that ecosystem is a real advantage Vimcal simply doesn't offer, on top of being free. For a lot of people, that combination beats paying for a feature (team overlap) they may only use occasionally.
Comparison at a glance
| Dimension | Vimcal | Notion Calendar |
|---|---|---|
| Price | ~$20/month | Free |
| Team time-zone overlap view | Yes, "Time Travel" | - |
| Notion workspace integration | - | Yes |
| Best for | Teams needing overlap visualisation | People already living in Notion |
So which should you pick?
Pick Notion Calendar if you're already in Notion daily and don't specifically need overlap visualisation. Pick Vimcal if that overlap view is worth paying for and speed matters more than integration. Since Notion Calendar is free, it costs nothing to try it first before paying for Vimcal, so there's little downside to starting there.
Where Atlas fits
If overlap across time zones is genuinely the whole problem, not a nice-to-have inside a bigger calendar decision, that's a narrower job than either app is built around. Atlas is a $4.99 one-time Mac app dedicated to exactly that: a world map of teammates and cities, shaded working hours, an auto-suggested best meeting time, and one-tap booking to whichever calendar you keep, Vimcal, Notion Calendar or anything else. It's a complement to this choice, not a third option inside it, and it works equally well alongside either calendar you eventually pick, so the calendar decision above and the overlap decision here don't have to be made at the same time, or even by the same person on the team.
