Most food scoring apps look at one thing: nutrition. They read the numbers on the back of the packet and give you a grade. That sounds reasonable until you realise a breakfast cereal fortified with vitamins can score well despite containing fifteen additives and being ultra-processed. Nutrition alone is not the full picture. It never was.
Cull scores every product on three factors: nutritional quality, additive safety, and processing level. A product that looks healthy on paper but is NOVA 4 ultra-processed gets penalised. An additive flagged in toxicology databases drags the score down. The formula is transparent — every calculation is visible inside the app, and every data source is cited. We do not hide behind a proprietary algorithm and ask you to trust us.
We built Cull for the UK. The product database, the barcode formats, the regulatory context, the currency on the pricing page — all of it is designed for British shoppers first. That matters because food labelling rules, approved additives, and available products differ by country. A scanner built for the American market is making assumptions that do not apply here.
Cull is free to download. Barcode scanning, health scores, processing breakdowns, and healthier alternatives cost nothing. Pro adds AI features for people who want to go deeper, but the core experience — knowing what is in your food — is free and always will be.
