I don't understand why things just have to be online-enabled nowadays. It seems like this app could be implemented with a daily-updating list of which products belong to which company, but my understanding is that they do a live server check, which wastes data and is very bad for privacy.
It seems like "talking to a server" is the default for everything nowadays, even when it doesn't need to be.

Hmm so it doesn't work online where I buy tons of stuff from Amazon Prime, and it doesn't work in brick and mortar because my brick and mortar and steel grocery store has absolutely dismal minimal coverage if any (maybe they have a jammer?). I suppose it would work great at the farmers market ... where everything is grown locally and mostly organically so it doesn't have much of a point anymore. Other than stunts in front of a camera for journalists I'm not sure where I could use this app.
