When it comes to app downloads, China and Mexico surged in the first fiscal quarter of 2015, says a report by the mobile analysts at App Annie.

China took the top spot for iOS downloads while Mexico now ranks among the top five countries for Google Play downloads, surpassing South Korea this quarter.

While we’ve seen Google Play lead the number of downloads across the globe and iOS facing a shrinking lead in revenue, Q1 2015 showed a huge jump for iOS in terms of revenue, to the tune of about 70 percent more (up from 60 percent higher in Q3 2014). Google Play continues to be top dog in downloads, though, with 70 percent more downloads than Apple’s digital storefront.

The report points out that the revenue gains seen by iOS are primarily a function of China and the United States, Apple’s two core markets.

While the U.S. continues to lead in overall iOS revenue, China’s surge is notable. It may have something to do with the iPhone 6 and 6 Plus launches in the populous country, as well as a trending demand for bigger screens in Asian markets, says App Annie.

Most of the downloads in China were in the Games and Photo & Video categories, with iOS apps like Tencent’s Pitu becoming one of the most popular photo app downloads in China.

Mexico climbed the download charts with both Games and Tools apps, with antivirus app 360 Mobile Security and keyboard replacement app G O Keyboard topping the download charts.
