The second new feature includes the voice activated virtual personal assistant Siri. The new Apple Store update brings Siri integration to the app and allows the user to ask Siri to search for prices and shop for Apple products and accessories. According to The Next Web, the Siri integration seems to work with the older version of the app. Regardless, both features are coming out at exactly the right time as the holiday shopping season is about to commence.
The updated version of the Apple Store app is now available for free from the Apple App Store.
