Photograph the back of the packet and it tells you only whether something you cannot eat is in it. No scores — it shows you the line exactly as printed. Korean and English. For Android phones.

| 🔴 It is in there | printed as "contains …" |
| 🟡 It may have got in | printed as "made in the same facility as …" |
| ⚪ Only seen in the ingredients | not in the allergy box the law requires |
Underneath it shows you the line exactly as printed on the packet. Do not take our word for it — read that line yourself.
| Yuka and similar | This app | |
|---|---|---|
| Reads a Korean packet | no | yes |

| Gives a score | yes | no |
| Separates "contains" from "may contain" | no | two lines |
| Needs internet | yes | never |
It leans on no database at all — only on what is printed on the packet in front of you. A brand-new snack reads just as well as a famous one.
This is not a diagnosis. If an allergy of yours is dangerous, do not rely on this app alone — read the packet yourself and talk to a doctor or pharmacist. That is why the printed line is always shown next to the answer.
A blurry photo or very small print cannot be read. When it cannot read, it says so rather than guessing.
Nobody has yet photographed a real packet with a real phone. The 409 labels measured so far were fed in as text. Packets are shiny and curved, and harder than flat paper. Try it and leave one line — the next build will fix what you find.
