We all know that App Store is bursting at the seams with whatever apps you might think. It´s certainly one of the major aces up Apple´s sleeve, but what we are amazed to find out is what a cashflow it generates. According to an AdMob´s recently announced figure, customers of the online store download software that´s worth $2.4bln per year. AdMod also compares it to the sales volume of Android Market that is currently estimated at the meager $60mln per year. There is a catch though – App Store is actively used by not only iPhone lovers, but iPod touch owners as well, although the former seem to be more active managing to generate revenues of nearly $125mln a month alongside of the $5mln reaped by Android app developers. Well, the whole thing adds up, since the iPhone is the most popular cell phone in the US and the service offered by AdMob is aimed at the same market, meaning these guys probably know what they are talking about. Moreover, it seems that half of all iPhone owners download at least one app per month, while this holds true for just 19% of Android fans.
