Cal.com v6.1 Changelog: Cal.com Companion launch, OAuth updates & referral terms

Hello, welcome to this month’s feature update! This month, we’ve focused on a few key areas to improve your experience:

Cal.com Companion launch

The wait is finally over! 🍾

Cal Companion is live. Native iOS and Android apps, plus Chrome, Firefox, and Safari extensions.
This has been in the works for a while. And we’re honestly proud of it: we’re the only free scheduling app with native apps across every store.

It’s not just “Cal on mobile”. It’s built for real day to day scheduling. Traveling? Your timezone changes on your phone, and your scheduling stays correct. On desktop, the extensions sit right where you work so sharing a link takes seconds, not tabs.
A few things you can do already:

  • Mobile apps with a polished native feel (Liquid UI on iOS, Material Design on Android)

  • Share booking links fast from your browser

  • Inject your Cal links directly into Gmail

  • Mark attendees as “no show” inside Google Calendar

This is v1.0, and we’re shipping more soon: widgets, Live Activities, push notifications, and more.
Try it out and tell us what you think.

Continue with Cal.com OAuth

We are continuing to invest in our Partnerships and Integrations App Store where anyone can publish their App that interacts with Cal.com.

Our recent move away from a full end-to-end white-label “Cal.com Platform” to a branded “Continue with Cal.com” experience is an exciting new direction for our API and SDK team to double down on our APIs and Atoms.

Support for managed users continues for existing customers but we are doubling down on a partnerships approach for new customers who want to build and integrate Cal.com.

To learn more about our OAuth clients and get listed on our App Store that receives millions of impressions every month, submit the form below.

Referral and affiliate program

We’ve updated the terms for the Cal.com Referral Program.

If you’re sharing your referral link (or plan to), please take a moment to review the updated terms directly from your referral dashboard:

👉 app.cal.com/refer

As a reminder, your referral link lets you:

  • Earn 20% per sale for 1 year on each paid user you refer

  • Give new users 20% off for their first 12 months

If you haven’t shared your link recently, now’s a good time to copy it from your dashboard and start referring.
