Google's Android is still the favourite among mobile software developers, ahead of Apple's iOS ecosystem.
The 2011 edition of the VisionMobile Developer Economics survey (PDF) found that 67 per cent of developers polled are working with the Google platform, up from 59 per cent in 2010.
The gain helped Android to maintain its developer lead over iOS, which rose from 50 to 59 per cent over the period.
Researchers noted that the huge market presence of iOS and Android helped the platforms stay at the forefront for developers.
The report estimates that more than 350,000 iOS applications are currently on the market, while Android apps number more than 200,000.
The mobile web platform has made some of the biggest strides in the market. The study found that 56 per cent of developers are working on mobile web applications, up from 40 per cent a year ago.
The researchers suggested that the increased interest in mobile web development is in part down to the versatility of web applications which can run on any number of platforms without the need for porting.
However, the biggest shift in next year's report may come, not from any of the top platforms named this year, but from Windows Phone.
The survey found that 35 per cent of developers intend to use the Microsoft platform, second overall behind Android and ahead of iOS and Chrome OS.
