How can I find iOS download statistics?
You have access to download and install statistics (and more) for your iOS WebAlliance Mobile application.
Though you can find cart statistics and search statistics for your iOS mobile application through the WebAlliance Admin panel, download statistics are best gathered directly from your Apple Developer Account. Your Apple Developer Account might have been created specifically for the WebAlliance Mobile application but the account belongs to you and you have access to a large number of statistics related to your application by logging into it.
Log in to your Apple Developer Account.
Click "App Analytics" to see some basic application statistics.
Click your application name to see more detailed statistics.
Apple has some useful information about the kind of application statistics you can access in their App Store Connect guide.
