These apps can help you if you want to find the best deals, keep track of your books, quickly create a shopping list or simply scan a QR code.

If you simply need an app to scan barcodes and decipher QR codes, then the Barcode Scanner app is what you’re looking for. With a fast scanner, the ability to keep track of all your scan history, and tools to create your own QR codes, Barcode Scanner takes the cake—that is, as long as you’re willing to pay the monthly subscription fee after your free trial.

If you love hunting for the best deals and bargains, the free ShopSavvy app is perfect for your coupon-clipping arsenal. While you can search for any item, the app’s real power comes from its barcode scanner.

Simply scan an item to compare the best prices in the app’s database of retailers. Once an item is scanned, the mobile app recommends different purchase options and products.
