The purpose of an application is to fulfill its users' needs .. But how to fulfill someone's needs without knowing him ? The answer to this question can be a market study, but once the application is launched and the linked with user's done, could we wait to know a little more ?

Of course some users are very interactive and tells us what they want, do they represent the anonymous majority ? That's not sure.

On the Internet, the solution has been simple : "observe in order to know". That's where came the tracking solutions among which the most known is Google Analytics.

Thus that's with pleasure that we found the interface concept of Google Analytics in the Flurry Analytics service who enables us to do what we already do on websites. A simple installation and then you get a thousand of useful information around the question "who are our users ?" : sessions duration, localization, hardware, everything we need to know better what they need and thus fulfill them.
