+## Locale note
+
+On Android, the picker will be controlled by the system locale. If you wish to change it, [see instructions here](https://stackoverflow.com/a/2900144/2070942).
+
+On iOS, the locale can be controlled from xCode, as [documented here](https://developer.apple.com/documentation/xcode/adding-support-for-languages-and-regions).
+
+For Expo, follow the [localization docs](https://docs.expo.dev/distribution/app-stores/#localizing-your-ios-app).
