The Strava app is currently available in the following languages
- Portuguese (Portugal)
- Portuguese (Brazil)
- Spanish (Spain)
- Spanish (Latin America)
- Traditional Chinese
Whenever possible, the Strava app will be displayed in the same language as your iPhone's system language. So, if your phone itself is set to use French, the Strava app will do the same.
For all languages not listed above, the Strava app will continue to be displayed either in English or in the language you have most recently used that Strava does support. At this point, it's not possible to manually set the Strava language to a different one than that of your phone's system.
Language tip: Some users have experienced the Strava app displaying a language that does not match that of their phone's system language. In this case, simply toggle your phone's language to a different option - then back to your language of choice; this should do the trick.
