One of the lesser-known features that are available on iOS 15 is the ability to change the language of the app that you use. No, we are not talking about globally changing the language on your smartphone, but rather individually changing the displayed language of apps. This is useful when you need to see the contents of a particular app in a specific language, but don’t want to change the whole device to that language due to reasons known to you. Maybe some apps make better sense to you in a native language while the overall interface is better in English. Whatever the case may be, iOS 15 allows you to make this change, albeit to just a few apps at the moment.
Step 1. Open the settings apps on your iPhone running iOS 15.
