Basics on App Store Scraping
Could anyone point me in the right direction for downloading app store statistics from:
-the Apple App Store -The Android Market -the Amazon AppStore
Specifically, I'd like to get the
-average selling price of apps -the top selling apps -the distribution of tablets vs. phones, etc. -total number of apps in store -free vs. paid apps
I've seen some sites like http://148apps.biz/app-store-metrics/
How do these sites get their data? There must be a way to export the whole app store database as a CSV file, or import it to MySQL and run queries.
Thanks much for any direction.
