The Oto app is available in three languages:

Choosing a language changes everything in the app — the interface, the therapy session audio, and the video content. It's a full experience in that language, not just translated menus.

Patients pick their language when they first set up the app, and can change it at any time:

The change applies immediately across the whole app. Their progress is unaffected — sessions completed in one language stay completed.

Languages outside the three above (for example Korean, Farsi, German, Portuguese, or Hindi) aren't currently available — a patient would need to be comfortable using the app in English, French, or Spanish.

A small number of patients who joined some time ago may have used the app in a previously offered language; those accounts now show the app in English.

We track requests for new languages, so if a patient needs one we don't support, let us know through the chat bubble — it genuinely helps us prioritise.
