It's the best! – Barcode Scanners Review

This app is designed to showcase the developer's SDK for integration into other apps, but it's an incredibly useful tool. It scans just about any code you give it, and the no-frills interface is wonderful for people who just want the raw data out of the codes. On top of that, it does a wonderful job of scanning and reading codes where other apps are almost impossible to use. It's also one of the few apps available that does more than UPC, Code 39, and Code 128… it has no problem reading PDF417 and mini PDF codes, QR, and DataMatrix codes.
