THE App Analytics, a new app data analysis tool for developers recently launched by Apple, has just gained new features and has left its beta phase.

What's new include crashes by version of app and operating system (in order to facilitate the identification of the cause of the problem); user payment analyzes based on Apple IDs instead of devices, possibility to see how many paying users you had on a given day (to assess the impact of possible price changes that campaigns generated) and filters by source to identify whether new users came from a particular campaign or website; possibility to relate two measures to better understand the reason for a certain performance of your app or your marketing campaign, evaluate conversion rate, sales by paying users, sessions by active device, and many other metrics.
If you are a developer and want to better understand the features of this tool, be sure to watch one of the sessions at WWDC 2015 that talks about it, Getting the Most out of App Analytics (something like Making the most of App Analytics).
