Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureRules differ by market: an ingredient allowed in one country can be restricted in another. Loook checks ingredients against regulatory lists and copy against claim rules. Allowed, restricted and prohibited ingredient results show their source; if rule data is missing, the ingredient is marked "review needed." Ingredients: cosmetics, food (US, EU, KR, AU); supplements (US, KR, AU); OTC actives (US, KR).
Tired of answering "where's the lab result for my batch?" over and over? COA Vault puts every certificate on your storefront so customers find it themselves, by typing their batch or lot number or scanning a QR code. Fewer support emails, faster answers, more trust at checkout. Upload your COAs, link each to a batch, and the app builds the lookup page, theme block, and print-ready QR codes.
- Ingredient screening against official regulatory lists in four markets
- Marketing-claim checks that flag drug-like or prohibited wording
- Every result cites its regulatory source — no black-box guesses
- Products are re-checked automatically when you add or edit them
- Upload COA PDFs and organize them by product and batch or lot number
- Print-ready QR codes (PNG + SVG) that open the right certificate when scanned
- Storefront lookup block — add it to any page in the theme editor, no code
- Lookup analytics, including not-found searches that reveal missing batches

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
