Does not give accurate carbs

When an Atkins product prominently displays that it has 3 grams of net carbs, and the highly rated app (this one) you just paid for comes up with -0.7 grams for the exact same item, I cant believe anything it tells me. I thought this app would be a step up from what I have been using, but no bar code scanning?? Thanks for nothing all you reviewers! You owe me $2.99!
