Label Shield looks for an "Ingredients:" header to identify the ingredient block. A few things that help:

• Make sure the "Ingredients:" header is visible in the photo.
• Good lighting and focus matter — try angling the package to avoid glare on shiny plastic.
• Hold the camera roughly parallel to the label so text isn't skewed.
• For very small print, get closer rather than zooming.

Different regulatory bodies reach different conclusions about the same additive. For example, titanium dioxide is banned as a food additive in the EU but permitted in the United States. Label Shield surfaces what each authority has actually published — we don't pick a side.

Open Settings inside the app → Your Region. You can pick any region manually, or use Auto-detect which uses your iPhone's region setting.

Open Settings inside the app and tap any tip in the Support Label Shield section. Any one-time tip removes ads forever on that device.

If you change phones, use Restore Purchases (same section) to bring your tip across.

Label Shield strives for accuracy but cannot guarantee scan results are 100% correct. OCR quality, label wording, and database coverage can all affect what's detected. Always read the actual label before making food choices.

If a scan misses a known additive or flags something incorrectly, email us at [email protected] and we'll look at the photo.

Currently only English food labels. We may add support for additional languages in a future version.
