Why you can't trust App Store data in China
Apparently, these Chinese companies get a pretty big sum of money from developers to push their apps into the App Store Top Ten. How much does this service cost? According to another photo found on a Chinese social media site showing one company's pricing list, getting your app into the App Store Top Ten requires an initial payment of $11,000. To keep your app in the Top Ten requires a tidy sum of $65,000 a week. These companies could be taking in a ton of money. If you look at the picture, you can see another bank of iPhones used in this operation..
As we said, there are a few companies in China who will perform this service for you. Which means that, at least in China, you can't believe the stats you see in the App Store.
