Every hurdle Android appears to have cleared in its race with iPhone seems to be followed up by another, more challenging barricade.

That's a thesis supported by the release of Mobclix's latest Android Marketplace infographic.

The firm's numbers suggest that, even though Android's monthly US sales have surpassed that of Apple, and app submissions to Android Market are now roughly level with the App Store, consumers are still spending far more money on iPhone.

App analytics

Firstly, Mobclix claims they download a larger number of apps. The firm's numbers suggest an iPhone user has 28 apps on their phone, with Android users coming in below on 17 apps per handset.

Added to that is also the suggestion that iPhone users spend far more money on in-app purchases in games than those on Android – seven times more in total, according to Mobclix data.

However, Android is by no means at the bottom of the tree. Twice as many Android owners make a purchase or payment on their handset than general smartphone users, suggesting the platform is performing strongly, but isn't yet in the same league as the App Store.
