VisionMobile have recently published Developer Economics 2012, the third in the report series that has set the standard for developer research. This report focuses on five main areas: The redefinition of mobile ecosystems, developer segmentation, revenues vs. costs in the mobile economy, app marketing and distribution and regional supply vs. demand of apps.

Here are some of the many insights from the report:

• The average per-app revenue is in the range of $1,200-$3,900 per month, depending on platform
