Many larger developers have forgone iTunes Connect entirely because of its lack of features for more advanced analysis. App Figures and App Annie are two of the more popular app analytics platforms, with many large developers using them to track sales figures across a vast array of categories.The lack of modern, useful reporting tools has been a source of developer complaints since developers have been able to complain. Given the size and value of the App Store, and the quantity of both developers and apps, iTunes Connects deserves the attention, and more. Hopefully this is just the beginning.
Apple also has an iTunes Connect Mobile iOS app, but it was not updated along side the website today. [Direct Link]
