## What is dtect?

dtect reads the printed ingredient list and marks your allergens: red (Alert) when they are in the list, amber (Caution) when the label only says "may contain". Under each flag you see the words it matched, so you can check it in a second.

dtect understands "gluten-free", "no milk" and look-alikes such as cocoa butter or buckwheat, and does not flag them. It reads the label itself, so there is no barcode and no product database to go out of date. That also works for imports, own brands and shop photos.

Text recognition can misread words, and recipes change. dtect helps you read a label. It does not decide whether a product is safe, so always check the packaging.

### 1/5 — Help

*2023-12-15*

I can not get mine to show up the results. It’s just a brown screen when I swipe up.

**Developer response:** Thanks for the honest review and sorry that it took this long. You were right about that result screen. Version 3.0 is a rebuild: you take one photo of the ingredient list, and the result comes up as a clear sheet over it. If you give it another try and have any more suggestions or problems, please check out dtect.app/contact.
