Apple tells you the number of sales (and the number of updates) in iTunes Connect . What they donβt tell you is how many people uninstalled your application or, more importantly, how many people still use it a few days after installing it.
You can get this information (and much more) using one of the third-party analytic tools such as Flurry , although Apple has recently begun to object to such services. Another option would be to collect the same information on your own server.
It would be great if Apple provided the best information, but unfortunately they are not working right now.
