How it works

Three taps. That’s it.

  1. Scan the barcode

    Point your camera at a packaged food. Barcode damaged? Type the number instead. No account needed.

Five verdicts

Five honest answers —not just yes or no.

Halal

No problematic ingredients found.

Result screen showing Kamar Geflügel Wiener marked Halal, 100% confident, because the product is halal certified according to OpenFoodFacts
Halal certified according to OpenFoodFacts, so the app marks it Halal.

Haram

Contains an ingredient the madhabs consider forbidden.

Result screen showing Tegut Soja Bolognese marked Haram, 100% confident, with a Contains Alcohol warning; white wine is in the ingredients
White wine is in the ingredients, so the app marks it Haram.

Doubtful

The source is unclear, or the ingredient isn’t in our database yet. Check the pack for a halal certificate.

Result screen showing Pringles Original marked Doubtful because of E471, with steps on how to verify the product
E471 can be plant- or animal-based, so the app shows how to verify.

Scholars Disagree

The madhabs disagree —
tap to see which ones and why.

Source Unknown

Not enough ingredient data to judge the product. Check the pack or ask the manufacturer.

Result screen showing Chio Tortillas Mexican BBQ Style marked Source Unknown: unable to verify this product, ingredients are missing
No ingredient list for this product, so the app can’t judge it.
A common myth

Plant-based means no meat. It doesn’t mean no alcohol. Wine, beer or rum can still be in vegan sauces, desserts and sweets — and that makes the product haram.

  • VegetarianLabel
  • White wineHaram

So don’t stop at the label. Halal One checks every ingredient, every time you scan.

Real scan: this Soja Bolognese is labelled vegan and vegetarian, and it’s Haram because of white wine.

Pick a school and see how it views the ingredient — exactly like the “Which Madhabs Disagree?” sheet in the app.

Important

Not a halal certificate — an educational tool.

Halal One is not a halal certification body and is not affiliated with any certifier. It helps you understand what’s in a product and how the madhabs view each ingredient. Results depend on the data available and can be incomplete. When in doubt, look for a recognised halal certificate on the pack or ask a scholar you trust.

Where our information comes from

Islamic research & manual classification

Each ingredient and E-number is classified per madhab through Islamic research and manual classification.
