Google's app store outperformed the sales growth of Apple's App Store over the past several months, but the latter still generates the most revenue, as well as profit.
During the last four months, the Google Play store for Android enjoyed a daily sales jump of 43 percent across 20 countries, according to figures measured by analytics provider Distimo.
Comparatively, sales growth for Apple's App Store increased by 21 percent on a daily basis. However, during January, the App Store's daily sales growth stood at 51 percent.
That said, daily revenue values in the App Store were already considerably higher than the revenue generated by Google Play. Distimo said that on an average day in November, the sales in the App Store surpassed $15 million. Google Play, meanwhile, settled for just under $3.5 million.
The United States was the largest market for overall app sales in 2012, which was followed by Japan, the UK and Australia. Google Play in particular saw the U.S. and Japan being the two largest regions for sales, followed by Korea.
Distimo added that a large number of apps available at both the App Store and Google Play made it increasingly difficult for users to discover new apps, subsequently hurting developers aiming to become successful commercially.
In November, seven apps accounted for 10 percent of all sales for the App Store for the iPhone, which was 11 apps back in January. 31 apps generated 10 percent of all free apps downloaded.
Ultimately, Android's revenue for apps has risen by 311 percent since January and 17.9 percent in November. However, iOS apps are four times more profitable than its rival.
