In the recent post on the app store comparisons from distimos http://techcrunch.com/2011/12/20/distimos-year-end-report-shows-why-developers-love-ios-iphone-4x-android-revenue-ipad-2x/
It states that the apple app store is the place to be for your applications if you are looking to make some money. The report claims that apple’s store produced near 4 times the revenue than google’s app market.
The report goes on to discuss the use of the freemium model for apps. It is interesting that the apple store shows the iPad and iPhone as separate areas.
I can’t wait to see what this report will look like next year. Overall, it seems that if you are looking to make some money you should build apps for iOS devices.
