The latest App Annie Market Index reported that during the second quarter, Google Play served 60 percent more downloads than Apple's App Store. By comparison, a year ago Google Play had only 10 percent more downloads than its rival. However, iOS apps generated 80 percent more revenue than Android apps.
In addition, the report noted that an influx of inexpensive Android phones has led to a growing number of Android downloads in developing markets, particularly India.
And, not surprisingly, the second quarter saw a big surge in sports app downloads, thanks primarily to World Cup soccer fans.
