app store guide appstore is a free Apple-centric shopping app that provides customers with the ability to scan products to see if they're compatible with their devices. The app also provides customers with the ability to see if they already own a particular item and get recommendations for what to buy next. Customers can also track their orders and see what accessories are compatible with their devices.

It's very easy to use, and you don't have to do anything else except take a picture of the product's barcode and wait for the app to find out whether it's compatible with your device or not. You can also track your orders and get recommendations for what to buy next.
