The App Store is a massive international phenomenon, and attracts Apps from all different languages. While Apple provides regional App Stores for different countries, the U.S. store still attracts a wide range of languages.
One frequent request we have received is the ability to block specific languages from the AppShopper lists. Language detection can be tricky, but we’ve now included a preference in your user profile that allows you to block Apps in non-western languages. This includes Chinese, Korean, Japanese, Hebrew, Russian, and a few others.
This feature is only available on the website at the moment, but will trickle into the App in the next major version. We are also working on other features to be more usable in countries outside the U.S.
