AdMob recently took on the task of examining the growth and highest concentrations of devices based on the iPhone OS versus that of Android-based gadgets. While Android OS devices have some high concentration levels across three continents, the iPhone has it beat with a larger distribution worldwide.
According to the findings in AdMob's April 2010 Mobile Metrics Report, there were 8.7 million Android OS devices and 18.3 million iPhone OS devices (iPhone, iPad and iPod Touch) in the US last month. The April release of the iPad in the US surely gave Apple a boost there, and that factors down to a 2 to 1 ratio of iPhone OS to Android devices.
Worldwide, AdMob found that there were 11.6 million Android OS devices versus 40.8 million iPhone OS devices, producing a 3.5 to 1 ratio.
As for where each OS seems to be more prominent, the greatest concentration of Android OS devices were in North America (75%), Asia (12%) and Western Europe (11%). Numbers for the iPhone OS devices reveal that distribution is spread wider across the world, although the biggest concentration is also in North America with 44% in the US and 5% in Canada.
The popularity of iPhone OS devices is developing fastest in Asia at staggering growth rate of 474%. But there are more Android-powered gadgets in China than iPhones, leading the way with a trio of HTC mobile phones (the Hero, Magic and Dream).
While it may seem from all of this that iPhone OS-based gadgets are outselling Android OS devices, the growth of Android products is pretty impressive. Yet the stats could become further lopsided if the iPhone really does become available with Verizon in the US and if/when the next-gen iPhone is released. However, even though ventures like the Nexus One didn't go well, Android's numbers and the success of handsets like the HTC Droid Incredible should serve as warnings to Apple not to get too relaxed. It isn't completely unlikely that Android could outstrip Apple's sales within two years.
