Not in your store yet

We'll email you the day Calla arrives.

Calla is live on the App Store and Google Play — but not in every country yet. Leave your email and we'll tell you the moment it lands in yours. Nothing else.

🔒 One email, when Calla reaches your country's store. No marketing list, no third-party tracking. Unsubscribe with one click.

While you wait

You don't need the app to be invited: anyone can open a Calla invitation link in a browser and RSVP — no account, no install. If someone sends you one, it just works.
