Halal Trace
Know what's in it, before you buy it.
Scan a product's barcode or photograph its ingredients label. Halal Trace checks every ingredient against a curated knowledge base and tells you where the product stands — which ingredient decided it, and why. When the answer isn't certain, it says so instead of guessing.
How it works
Three steps, and the first two happen on your phone.
-
Scan or photograph
Point the camera at a barcode, or take a picture of the ingredients label. You can also pick an existing photo from your gallery. Before the verdict is worked out, you can review and correct the text that was read off the label.
-
Every ingredient is checked
Each ingredient and E-number is matched against a curated knowledge base, in English, German, Swedish, Spanish and French. Nothing is skimmed or sampled — the whole list is read.
-
You get a verdict, and its reason
A fixed set of rules turns those matches into halal, haram or doubtful, and names the ingredient that drove the result. One tap opens that ingredient's entry to see why it's classified the way it is.
Why you can trust the answer
An assessment you can't examine is one you have to take on faith. This one shows its working.
Every verdict names its reason
You never get a bare answer. The result names the ingredient that decided it, and that ingredient's entry is one tap away — what it is, where it can be derived from, and why it's classified the way it is.
It tells you when it isn't sure
Uncertainty is reported as doubtful, never dressed up as a confident answer. If a product can't be resolved — no signal, no data, an unreadable label — you are told exactly that, rather than handed a guess.
The same product, the same answer
Assessment follows a fixed set of rules, applied identically every time. Scan a product twice, or hand your phone to someone on the same settings, and the verdict doesn't drift.
Every classification has a source
Ingredient rulings are not opinions typed in from memory. Each entry in the knowledge base records where its classification comes from, and how a particular verdict was reached is shown alongside it.
Clearly haram is never softened
The strictness setting changes only how undisclosed or ambiguous sourcing is treated. Pork, alcohol and other unambiguously haram ingredients are flagged on every setting, including the most lenient.
Where AI is used, it is labelled
Nearly every verdict comes from the curated knowledge base. For a product nobody has assessed before, an AI model reads the ingredients — and that verdict is marked as AI-assessed in the app, so you always know how an answer was reached.
Built for the aisle
Fast, quiet, and useful when the shop has no signal and someone is waiting behind you.
Works offline
The knowledge base lives on your phone, so reading a label resolves without a connection. Nothing is uploaded just to get an answer.
You choose how strict
Strict, Balanced or Lenient — it governs only how an undisclosed source is treated, and the setting you were on is shown with every result, so a verdict is never ambiguous about the standard it applied.
Your own rulings are respected
Where scholars differ, record your own position on an ingredient once and every future scan will follow it — and will tell you when a verdict depended on it.
More than the verdict
Where the product data has it, you also see declared allergens, cross-contamination traces, and vegan, vegetarian and palm-oil information.
It tells you when something changes
Scans are saved so you can find them again, and if a product you saved is later reassessed, you're told — a recipe can change without the barcode changing.
No account, ever
No sign-up, no email, no profile. Your scan history, favourites, settings and personal rulings stay on your device.
What Halal Trace isn't
We would rather tell you this plainly than have you find it out later. Halal Trace is a tool for reading and assessing ingredients, not a religious authority, and its verdicts are not fatwas. Product formulations change without the barcode changing, the product databases it draws on are community-maintained and uneven, and an ingredient or allergen missing from them may still be present in the packet in your hand.
So: read the packaging yourself, and consult a scholar you trust for a ruling. If you have a food allergy, treat the allergen information here as a prompt to check, never as a clearance. And if a verdict looks wrong, report it straight from the result screen — corrections are the fastest way this gets better for everyone.
Where the data comes from
Product information comes from Open Food Facts, an open database made available under the Open Database License (ODbL), and from the U.S. Department of Agriculture's FoodData Central. The ingredient classifications are our own, curated entry by entry, with the source recorded for each one.
