Crashed every time I tried it.

Repeatedly crashed (quit unexpectedly crashed, send a report to Apple, not 'I can't read that picture' crashed) trying to read a barcode in a .jpg picture I just took of the codes on the bracelet they gave me in the hospital today. I've deleted the app and am moving on to try something else.

Works for many codes

I found it easy to use. It recognized barcodes embedded in photographs and read them correctly. However it did not work with some barcodes I found in some old (1980s) computer magazines - however these may have been meant for a proprietary reader. It did read any modern barcode or QR I threw at it.

You can copy the data from the output, you just have to double-click on the field you want, then it is "unlocked" and you can copy it.

As someone else pointed out the interface is functional and spartan - IMO, we need more applications like this.

it's FREE!

I won't waste anyone's time talking about anything except what this app does great:

1. Reads barcodes from images, including super tiny QR codes
2. Costs nothing
