Apple's iTunes App Store contains more paid-for applications than its rival Android Market, according to research conducted by application store analytics firm Distimo.
The company found that 80 per cent of the applications offered on the iTunes App Store were paid for, with iPhone applications accounting for 73 per cent of all paid applications.
Distimo said that 57 per cent of applications for the Android Marketplace were offered for free.
The study also said that Microsoft's Windows Market had the smallest proportion of free applications, with around one-fifth of the applications for the platform available to download for free.
The company compiled its results after surveying the App Store for iPad, App Store for iPhone, Google Android Market, Nokia Ovi Store, RIM's Blackberry App World, Windows Marketplace and Palm App Catalogue.
The average price for a paid app on the Apple App Store was just over $4, while the average price for an Android app was $3.29.
According to Distimo's figures, the average price of paid-for application across all application stores, excluding Blackberry App World and Windows Marketplace, was $2.
