Android is a phenomenal success story, skyrocketing from nothing to surpass both RIM and Apple and become the dominant smartphone platform in only a couple years. Recent studies however indicate Android may have lost some lustre with developers, as iOS seems to be the primary platform developers are working on.

Or, maybe not. Just in the past month or so, there have been conflicting stories over which platform attracts the most developers.

Which is it? When you're dealing with studies, surveys and statistics, it is often hard to tell. You have to understand the angle of the company conducting the survey or the agenda of the organisation that commissioned the study.

There are some legitimate reasons why a developer faced with a decision between creating an app for iOS or an app for Android might lean toward the Apple side of the fence.

iOS is a larger market

Android may have surpassed Apple in the smartphone arena, but iOS is bigger than smartphones. If you include iPads and iPod Touches in the mix, iOS has an audience of about 200 million possible customers compared with only 135 million for Android.

Android activations seem to be outpacing iOS, so Android is closing that gap. But, when the iPhone 5 along with iOS 5 and iCloud hit the street, things may shift back in Apple's favour.

iOS App Store is more dynamic

Not only does the Apple App Store have more apps than the Android Market, but there is more activity and greater turnover in the App Store.

Distimo, a Dutch mobile apps research firm, explains lower Android Market sales with the following statement: "The top 10 free and top 10 paid applications together have seen only 26 applications in the Google Android Market, while there have been 94 applications in the top 10 free and paid in the Apple App Store for iPhone."

According to a report from Distimo, 25 percent of the free apps and 79 percent of the paid apps in the Android Market have been downloaded fewer than 100 times, and only two paid Android apps have managed to sell more than 500,000 downloads. The report contrasts that with six paid iOS apps that had each sold more than 500,000 downloads in only a two month period, and only counting US sales.

iOS users buy more, and pay more

This is really the main point that matters. Android could have a larger audience than iOS, and have more apps in its market with a high degree of turnover in terms of which are the top or most downloaded apps, but most developers are in it to make a profit.

GigaOM recently shared some data from Piper Jaffray analyst Gene Munster indicating that iOS users buy more apps and pay more for them than other platform users, including Android. Munster reports that an average iOS user downloads 83 apps (up from only 51 the year prior) at an average sale price of $1.48 (up from $1.29 the previous year). Munster also states that the average sale price of the top 30 paid iOS apps is up 36 percent from 2010 to $6.32.

These points, combined with the slew of patent infringement lawsuits plaguing Android, suggest that the glory days of the Android OS may be waning quickly.

I am not suggesting that Android will fade into oblivion, just that patent licensing fees and a stagnant app store will not support the kind of rapid growth that Android has enjoyed up to this point.
