It's an App, App World

Greystripe, a rich media mobile advertising network, just published their quarterly Consumer Insights Report. It shows that users average 9.6 minutes of engagement per session on free iPhone applications -- not to shabby. Based on data generated via the 600 free, ad-supported iPhone apps in their network, consumers access apps 19.9 times over before discontinuing use. I'd say that's about how many times I used iFog and TipStar before they fell off the face of the (iPhone) earth.

Additional findings worth noting:

• 42% of the firm's free iPhone app users have an HHI of $78K+
• 15% earn $165K+ (extremely affluent)
  
• 91% are involved in their household purchasing decisions
• 65% of Greystripe's users said they would interact more with an ad if it were an interactive ad, as opposed to a static ad
  

Greystripe has made a name for themselves as the only mobile ad company that offers full-screen Flash ads on the iPhone. One of these formats is the Tailgate rich media ad format that the user interacts with before they access the actual game before they download. Basically, this is an advergame for the iPhone with the benefit of reaching a wide audience.
