Best Barcode App & Best QR Code App?

[Alvin777]

Hello Mac & Apple friends what's the best barcode app & what's the best QR Code app (preferably totally free) you've tested, that's even smart enough to read accurately even with glare, curved (like cans) & crumpled in the packaging (and surface) & low lighting even?

Thank you, advanced happy Easter.

You don't need one, just open the camera app and aim at the QR code and the link will appear in the viewfinder.

Oops sorry, I missed the barcode part, I'm not sure about barcodes.
