During the second quarter of 2013, Google Play surpassed Apple's App Store in app downloads for the first time, a study has found. Despite this, Apple still brought in more than double the revenue from its App Store than Google did from Google Play.

App analytics firm App Annie's latest Market Index report reveals that Google Play's app downloads totalled 10 per cent more than the iOS App Store in Q2 2013, but that the iOS App Store still managed to generate 2.3 times the amount of revenue than Google Play.

The growth of the Google Play store could be thanks to emerging markets including Russia, India and Brazil, the study found.

Looking closer, the report highlights that the Games category continues to dominate downloads from the iOS App Store. In the second quarter, around 40% of iOS app downloads were games.

When it comes to revenue, games accounted for almost 75 per cent of the total iOS App Store revenue in Q2 2013.

Entertainment and Photo & Video categories continue to be popular among iOS users, securing the second and third spots in terms of downloads, but for revenue, Social Networking and Music were the second and third biggest earners.

For Google, Games were also the most popular type of app downloaded from the Google Play store in Q2, and also brought in the most revenue, at around 80 per cent of total revenue for the quarter.
