I have tried a number of Apps to read/scan QR Codes (all bar one tested were free) and I have to say that there isn’t one that stands out above the rest, so I’ll review the ones I end up using more than others below.
QR Code Reader and Scanner (iPhone/iPad/iPod): Scan QR Codes you find on your travels, in magazines, on posters, etc with this useful and free app. Use the history feature to view/review your past scans but make sure the codes are on a flat surface and in a well lit area (and not on a glossy finished page, it’ll prove difficult to scan).

Scan (iPhone/iPad/iPod): Billed as the “the fastest, simplest and most user-friendly QR Code and barcode scanner available” it’s certainly the quickest to be ready to scan a code from launch, but is not always able to scan the code if you don’t hold the camera square on to the code, and in good light.

Quickmark (iPhone/iPad/iPod): This one is not free (£0.69) but it is by far the most powerful of all the apps I use, enabling you to scan and create codes on your device (based on URLs, contact details, plain text, etc) or you can use a photo you’ve saved in your camera roll to scan after the event, if you’re in a hurry. It is also worth checking out the Quickmark website if you use other types of mobiles as they have developed the app to work on other OS too, as well as a QR Code reader desktop solution! For the price it is well worth it, in fact if it could only recognise the code quicker and start quicker then this would be the best app I’ve downloaded.

BeeTag (iPhone/iPad/iPod): BeeTag will scan a QR Code as well as a normal code (as do the others above) but this app also acts as a price checker on normal barcodes. There is no history feature with this app but the list of available options when you scan a code is impressive, giving you the option to view the code, view/show the URL, save or send the URL to an email or SMS recipient, or save it to a favourite list (is this the history feature?).

Unfurlr (iPhone/iPad/iPod): This is a new one to me and I’m still trying it out but so far it’s quite good. It’s quick to launch and only has one function: to scan the code. The advantage of this app though is that it traces the codes path “so you know whether or not it’s safe before visiting the underlying web site.” I’m not sure how it does this, or based on what it makes the %age analysis of trustworthiness, reliability, privacy, and child safety, but it is a good reaction to some comments about QR Code ‘honesty’ that are doing the rounds at the moment (Mashable: QR Code Security).

This is not an exhaustive list or accurate survey of the apps, or of those that are available, but just the ones I’ve downloaded, kept, and use.
If you use one not mentioned above than please leave a comment below and review it (link as well if you like) for others so they can see whether it is worth downloading, or not!
