Sorry if this has been posted before. http://www.gamasutra.com/view/news/37350/Report_InApp_Purchases_Make_Up_72_Of_iPhone_App_Revenues.php Looks like a more than excellent hint for us developers.
hmm short news article backed up by numbers from a company i never heart of before (which does not mean anything) for having a good insight into the appstore metrics.. weird.. never heard of the company distimo before.
Well, it seem like Distimo is quite visible on the net an has been quoted regularly. http://www.google.com/search?hl=en&q=distimo+report
well the question of if its being quoted because of the way they write their headlines or because of the quality of their analytics.. of course if you search explicit for their name you find stuff.. but if you search with broader terms like app store, ios , analytics whatever i don't find anything on them and the "old" big dogs like flurry and appannie pop up who actualy have a userbase they can base their analytics on.. not sure where thoose distimo guys have their numbers from..
Addendum... I believe that it is crucial to assess the reliability of the mentioned company. This is very important. Unfortunately I have trouble doing so and would be happy to receive some hints there.
Yeah... who are they? At any rate, people like to try before they buy with unknown developers, enough said.
Well... I have exchanged some emails with the guys at Distimo. They are very friendly and helpful. They use publicly availabe information, that includes rankings, reviews, ratings et cetera, from the App Store. On top of them they rely on information provided by developers. This is were the secret is buried This information seems to be gathered from the data that is provided by the Apple developer platform. Of course you must voluntarily make this data available. The exact nature of the collected data and the amount of data is however unknown.
Well I and a number of other developers that I know use Distimo for tracking of their apps. One thing that Distimo do well is allow developers who deploy to multiple operating systems (such android, blackberry and wm7) pull store data as well. Makes it a great one stop shop. But if you are a iOS only dev then App Annie and App Figures are also good!
