How to Change the Language of One App on iPhone
An iPhone can change the language of one app without changing the system language when the app supports per-app language settings. Open Settings > Apps > select the app > Language, choose a language, then relaunch the app. Older iOS versions may place the language option directly inside Settings > [app].
🤔Note:
Per-app language changes work only when both the app and the iOS version support the feature.
Steps
- Open Settings and tap Apps.
- Select the app requiring a different language.
- Tap Language, then choose the preferred language.
- Close and reopen the app to apply the language change.
- If the option is unavailable, check Settings > General > Language & Region > Apps, select the app, and choose a supported language.
Common Issues and Fixes
- The Language option is missing: The app may not support per-app language settings. Check the app’s internal settings for a language selector.
- The selected language does not apply: The app may still be running in the background. Force-close the app, then open the app again.
- Only a few languages appear: The app developer controls available translations. Install the latest app version and check the developer’s supported-language list.
- The app returns to the previous language: An app update, reinstall, or account setting may reset language preferences. Repeat the language selection after updating or reinstalling.
- The language changes across the entire iPhone: The system language setting was changed instead of the app language setting. Restore the preferred option under Settings > General > Language & Region.
Quick Tips
- Per-app language changes work only when the app and iOS version support the feature.
- Some apps use the first compatible language in the iPhone’s Preferred Languages list rather than a separate app setting.
- Restarting the iPhone can resolve language display errors after changing regional settings.
- Language and region are separate settings. Currency, date format, and measurement units may remain unchanged after changing an app language.
💡Protip:
If an app does not provide a per-app language option, look for a language selector inside the app or adjust the order of languages under Settings > General > Language & Region.
Related Questions
Can one app use a different language from the iPhone?
Yes. The iPhone supports a different language for individual apps when the app provides localization and iOS exposes a per-app language control.
Can an app language change without changing the system language?
Yes. Select the app-specific Language setting instead of changing the main option under Settings > General > Language & Region. Apps without per-app language support require an in-app language setting or follow the system language.
