What GoodSwap does
GoodSwap is an iPhone app for scanning before you buy. It covers food, drinks, supplements, beauty, household, baby and pet products in the United States, the United Kingdom and Canada.
- Scan a barcode, point Label Lens at an ingredient list, or snap a photo of a product we don’t know yet.
- Read the receipt. GoodSwap gives a 0–100 score, and The Receipt lists each point in or out, the reason, how strong the evidence is and its source.
- Swap. Swaps are the same kind of product, score at least 10 points higher and are sold in your country.
- Your lens. Lenses such as Real Food, Kids, Pregnancy and Allergy-Safe add a personal verdict. They never change the score.
- In the aisle. Scores are computed on your phone, even with no signal, and Recall Radar checks public recalls against the products you have at home without telling us what you own.
This website shows the same scores and receipts for popular products, ranks the healthiest products by category, explains ingredients from A to Z, and publishes stories about recalls, rules and studies.
How scores are made
Every product starts at 100. A fixed, published set of rules takes points off, or adds a few back, for what the product contains, how processed it is and its nutrition, with matching rules for beauty, household, supplements, pet food and baby products. Each change is a line on The Receipt with its reason, its evidence tier and its sources.
The rules are deterministic: the same product with the same facts always gets the same score. Every receipt prints the score version and the knowledge-base version it was computed with, and any change to the method ships as a new version with an entry in the changelog.
Read the methodology: every rule, threshold, cap and exemption, with a worked example.
Where the data comes from
- Product facts come from Open Food Facts contributors, under the Open Database License (ODbL), with Open Beauty Facts, Open Products Facts and Open Pet Food Facts for other kinds of products; from USDA FoodData Central branded foods; and from labels our users photograph, which are marked “AI-read” until they’re confirmed. The licenses and credits are on Open data.
- The ingredient knowledge base (concern levels, effects, regulatory status and references) is written by GoodSwap from primary sources: laws, regulators, IARC classifications, agency assessments, peer-reviewed studies and dated independent tests. Every claim links to its source on the ingredient’s page. No medical professional has reviewed these entries yet, and each ingredient page shows its review status.
- Recalls come from public notices by the FDA, USDA FSIS, CPSC, Health Canada, the CFIA and the UK Food Standards Agency, and every alert links to the agency’s own notice.
- Stories are written by GoodSwap. Every claim links to its source, and lawsuits are shown as allegations, not findings.
We don’t copy third-party ratings or test results into our databases. When an outside test matters, we cite it and link to it. More on data and updates.
Editorial policy
- Published rules decide every score. Scores come from fixed, deterministic rules that anyone can read. A rule only changes with a new version number and a changelog entry.
- Every point cites a source. Sources follow a hierarchy: the law, then authoritative classifications such as IARC’s, then agency assessments, then peer-reviewed studies, then dated independent tests.
- AI reads labels; it never scores. AI only reads the text on photos of products we don’t know yet. What it reads goes through the same rules as every other product. It never writes a receipt line, picks an evidence tier or chooses a swap.
- Brands can’t pay. Not for a score, a ranking, a badge or a spot in the swaps. Lab results supplied by a brand are labeled “brand-supplied”.
- The regulators’ own words. “Banned” only when something is banned; otherwise “not permitted in”, “requires a warning label in” or “restricted to”. Lawsuits and legal notices are allegations, never scored as fact.
- No silent penalties. Missing data is skipped and noted on the receipt, and confidence drops instead. When we can’t stand behind a number, we show “Not scored yet”.
