The strongest starting point

Scan the ingredient label, not just the front of the pack

The printed ingredient list contains the detail an allergen check needs. Capture it clearly and keep every line visible.

What to know

A clearer way to use this check

Use the method that fits the information available, then verify the exact food before making a decision.

Place the label on a flat surface, avoid glare, and include every ingredient line and nearby allergen statement.

The app extracts the available text, compares it with your profile, and shows the ingredients connected to the result.

Small print, folds, reflections, and missing label sections can affect the analysis. A second photo is better than relying on incomplete text.

Choose the best input

Use a complete ingredient label whenever it is available. Photos and product-name checks are helpful starting points when packaging is missing.

Compare the three methods and learn what each one can - and cannot - show.
