Chance Miller, 9to5Mac:
Apple today is making it easier for users to view purchase history directly from their iOS devices. The company revealed in an updated support document today that you can now view your App Store and iTunes purchase history in the Settings app on iOS.
Previously, as the support document notes, this functionality was only available through iTunes on Mac and PC. While you could view purchase history via the App Store and iTunes Store on iOS, it was purely for re-downloading purposes and didn’t show detailed pricing information.
Here’s the referenced Apple knowledge base article.
I followed the instructions, jumped through the hoops, tapped Purchase History and it worked as advertised. Good to know.
