Device Language and Region Settings (iOS)

Your iOS Device Language & Region Settings controls how data is displayed, the language in which the app is displayed, and in some cases how search results are prioritized.

For example, in TPE and TPE 3D, if your device is set to UK rather than US, a search for "Keswick" will return Keswick in England rather than Keswick in the USA, by default.

You can check or change your device's Language & Region settings, by going to the iOS Settings app, choosing General, then Language & Region:
