What is the app that scans products to see if they are good or not?

Excuse me, I'm curious about this technology you mentioned earlier. Could you please elaborate on the app that scans products to assess their quality? I'm wondering how it works, what kind of information it gathers, and if it's reliable in providing accurate evaluations. Additionally, are there any limitations to this app's capabilities, and what industries does it cater to specifically? I'd appreciate it if you could provide a brief overview of its functionality and potential benefits for consumers.
