It should be noted that the ad-based Android app has been on the market a good two months less than the other products in the table. It was released some time in March 2011 (exact date not noted) and the results are collected today, July 11th.
As you can see, the "income" from the ads from the free version of Flags and Capital Quiz is ridiculously low, even if we compensate for the missing two or three months of market time. Although the volume of the sample data in this "analysis" is far from big enough to draw any absolute conclusions, I think it gives some interesting indications. I for one am not going put all my eggs in the basket of ad-based apps for the Android platform.
As a fun fact I included the earnings I've had for ads on this page (Google Adsense) in the same period of time. I guess one can't conclude that blogging is more lucrative than writing phone apps based on this, but well...
When this is said, a interesting new feature has been introduced to the Android platform since I last wrote. Well a lot of interesting new features have been introduced actually, but the one of interest in this context is the ability to exexute in-app billing on the platform. This basically gives us the same possibilies as the Trial mode flag on the Windows Phone 7 platform. It just takes a couple of hundred more lines of code ;-)
Still I'm quite interested in seeing the development of the use of in-app billing in the developer community. Because of the quite crappy income genereated from ads, I'd expect more developers to go for the Trial/Full version licensing model in the time to come. I know a great deal already are, by publishing two separate apps, but I think it will be even more popular with the new model.
