Question

I am developing mobile application for android and for iphone. I have an advanced handmade logger which tracks every user action and sends logs to server. If there is no internet it stores logs and sends them later.
The questions are is there a logging system on the market, with which I can track anything I want(method logger.write I assume :))
And the main question: which system I should use for complex data analysis? F.ex. to see how much time users with specific phone model spent on given page after visiting another page.

Answer 1

To answer your main question I suggest you to use Flurry Analytics. I am using it on Android and it is very simple to integrate. Everything you need to know is on their WikiPage.
