Choose Open Food Facts if you want the open food database and to contribute product data directly. Consider VeganCheckr for a focused vegan and vegetarian checking workflow. VeganCheckr uses Open Food Facts for barcode lookups, so switching apps is not necessarily an independent second check.
Check your own packetTry one product you actually buy before deciding which app fits your routine.
- Scan its barcode in VeganCheckr and match the product name, variant and ingredients to the packet.
- If the record is missing or different, use a clear ingredient photo instead of accepting the barcode answer.
- Keep unresolved origins unresolved. A second app using the same record is not new supplier evidence.
Free to download; optional Premium. Full ingredient details or explanations may require an upgrade. Features differ on iPhone and Android; Android photo recognition supports printed Latin-script labels. A result is not certification or an allergy-safety guarantee.
What are you trying to do in the aisle?
If you want to browse a food's recorded ingredients, nutrition and community contributions, Open Food Facts is a sensible starting point. If your immediate question is “what here needs a vegan or vegetarian check?”, VeganCheckr puts that task at the centre of its interface. This is a difference in workflow, not evidence that one app knows the origin of every ingredient.
Disclosure: this site publishes VeganCheckr. We reviewed the official documentation and store listings linked below, and checked our own product implementation. We did not run a blinded accuracy study or test the two apps on a representative supermarket basket.
VeganCheckr and Open Food Facts compared
| Question | VeganCheckr | Open Food Facts |
|---|---|---|
| Main purpose | Vegan and vegetarian food checking, with ingredient findings | An open food database, with nutrition and ingredient analysis among its features |
| Barcode evidence | Uses Open Food Facts product records; coverage depends on the available record | Displays and accepts community-maintained product information |
| Missing ingredients | An ingredient-photo workflow can help check the current packet; Android also accepts text | Contributors can add or correct products and ingredient information; its documentation also covers OCR-assisted analysis |
| Uncertain origins | Some findings remain uncertain and need a maker's answer | Its analysis distinguishes yes, no, maybe and unknown; parsing can be incomplete |
| Cost | Free to download, with optional Premium; full ingredient details or explanations may require an upgrade | The project's free, open-data app is the natural option to compare if you want to contribute to the database |
| Availability | iPhone and Android; features differ by platform | iPhone and Android; check the current local listing |
The shared-data detail that matters
VeganCheckr's barcode lookup uses Open Food Facts. That matters more than a long feature checklist. Suppose a jar has a complete, current record in the database: both tools may start from the same declared ingredients. Suppose the recipe changed last month: trying the same barcode in a second app can return the same older record.
Two matching answers are reassuring only to the extent that their evidence is independent and current. They are not two manufacturer confirmations. Compare the full product name, variant, country and ingredient panel before relying on either result. A barcode identifies a database entry; it does not inspect the food in the jar.
For a missing or mismatched entry, follow our product-not-found checklist. Open Food Facts is also a useful place to contribute a correction with a clear product photograph. Check its contribution instructions and avoid uploading personal information visible in your photo.
A label example: bread containing E471
Imagine a bread label that lists wheat flour, water, yeast, salt and E471. This is a worked example, not a photograph of a tested loaf. A readable ingredient list establishes the presence of E471. It does not necessarily establish every input's origin. A parser can correctly identify the additive and still leave the vegan question unresolved.
Look for a product-specific vegan statement or ask the maker about the relevant source. Our E471 evidence guide explains why the additive's specification and the finished food's suitability are separate questions. Switching interfaces cannot supply a fact the label and maker have not disclosed.
When Open Food Facts is the better fit
Start there if you value the underlying open database, want to inspect or improve records, or prefer a broad food-information tool rather than a dedicated vegan-shopping interface. Its ingredient-analysis documentation makes the uncertainty states explicit, which is useful when you want to understand how a tag was produced.
Do not dismiss the project as “just a barcode reader”: its documentation covers ingredient analysis and OCR. Nor should you assume its community-maintained data is automatically current for every market. Check the record against your packet whichever interface you use.
When VeganCheckr is worth trying
Try VeganCheckr if your recurring task is checking vegan and vegetarian ingredient findings, including E-numbers, rather than contributing to a general database. Use a familiar packet to judge whether its presentation helps you understand the result. Ingredient-photo checking is especially relevant when the barcode record is absent, but a photo cannot reveal a hidden processing aid or an undisclosed supplier source.
Check the actual in-app purchase screen before upgrading. “Free to download” is not a promise that every ingredient explanation is free. Android photo recognition supports printed Latin-script labels; platform features and privacy disclosures differ. Our platform-specific privacy policy is a better reference than assuming one store's label covers both apps.
