Recent statistics from AppAnnie show that localization is a key factor in iOS app downloads, especially in China. Just under 50% of iPhone and iPad apps that were downloaded in China had local language names.
Other countries are also featured prominently in these stats, with Korea having the most local language apps in the top 25 of monthly free downloads for the iPhone. France was second behind China on iPad apps.
Meanwhile, the US were the country to have downloaded the most free apps, in front of the Rest of the World category and China.
