Balloon is currently only available in English. We know this is a limitation for many of our users around the world, and adding support for other languages is something we'd love to do in the future.
We can't give a specific timeline yet, but it's on our radar based on user requests. We'll announce it when new language support becomes available.
In the meantime, if you have any questions or need help navigating the app, don't hesitate to reach out to our support team! We'll do our best to assist regardless of language.
