First, check if the required language is supported in Flo. The app is currently available in Arabic, English, Danish, Finnish, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Norwegian Bokmål, Polish, Portuguese, Russian, Simplified Chinese, Spanish, Swedish, Thai, Traditional Chinese, Turkish, and Vietnamese.
If your preferred language is on the list, go to your device settings and change the language. Flo will then be displayed in this language too.
Go to Flo > Menu > Settings > Change Language. There you’ll need to tap the required language. Then remove Flo from the phone memory (open apps) and restart. When you reopen it, the language will be set as required.
