Barcode is the ultimate code scanner iPhone app (runs on iPad as well). It can scan, parse the contents of codes then offer actions depending on the contents.
Unlike competing apps, this scanner can scan all common kinds of codes reaching from the well-known QR codes, all sorts of EAN codes, to even Data Matrix codes! It’s one of the fastest and most precise code scanners in the App Store. It also allows using the built-in flash light (iPhone 4 + 4S) when scanning.
Use it for pure recognition, for price comparison with Amazon, or instantly browse the web for the scanned information. Use its ability to directly apply the contents of any code you scan: you can add calendar events to your calendar, vCard information to your address book, or open maps to the right location – all with just one touch. And that’s only the beginning.
You can also easily share the scan results on Twitter and Facebook.
