For now, the Toggl Track mobile apps have support for English, Japanese, Brazilian Portuguese, and French. This is based on your device language settings.
The web app is only available in English at the moment, but we are working on translating it into other languages in 2020 as well.
Interested in helping us translate Toggl Track into your native language? Reach out to our support team and let us know!
Note: You may have read blog posts referring to multilingual capabilities, but these were temporary experiments we stopped due to performance issues.
