Generates "bar code" types: QR Code, PDF 417, Code 39, Code 128 – QR Code Generator, Scan QR Review

Checking all the options it seems you're limited on barcodes for URLs and to the above mentioned types. The app doesn't work with a even standard UPC or ISBN. App was free with aggressive ads, had to wait to click on 3 full screen ones when I went directly into the menu option to purchase the app. Basically, it's $4 and they don't want the license managed through App Store. It is useful and quick for reading codes and there are a few preferences to select (sound, animation, save history, open directly in browser or give an option to "Share" with another app.
