Horrible app - hard time recognizing barcodes

Bought this app for my visually impaired mom. When it works, it works great. But most of the time even with a perfect image of bar code, the app cant see it. Seems to like boxes better than cans. Only worked about 10% of the time. Please note I am not complaining about local brand bar codes needing to be added. If that is all it was this would be a great app. But it just doesnt "see" the barcode to begin with. App should been free or at least no more than $3.
