Yllo — Scan. Know. Eat with Confidence.
Tired of squinting at tiny ingredient lists, wondering if a product fits you? Yllo scans any barcode and instantly highlights what's inside — color-coded for your personal sensitivities — so you can shop with confidence.
Whether you avoid lactose, gluten, FODMAPs or histamine — or simply want to eat cleaner — Yllo turns messy ingredient labels into a clear, visual answer in seconds.
WHAT YLLO DOES
SCAN any food barcode with your phone camera.
EXPLORE the ingredient library — search any food, additive, or E-number, filter by category and intolerance level, even before you go shopping.
COVER 12 common intolerances: FODMAPs, Lactose, Histamine, Gluten, Fructose, Oligosaccharides, Sorbitol, Sucrose, Tyramine, Salicylate, Nickel, Oxalates.
HIGHLIGHT each ingredient in green, yellow, orange, or red based on YOUR personal intolerance profile.
RECOGNIZE food additives — E-numbers (E202, E322, E500, E503…) detected in any language, alongside their alternative names (e.g. "E322" = "soy lecithin" = "lécithine de soja").
SEE Nutri-Score, NOVA group, Eco-Score, allergens, vegan status, and per-100g nutrients at a glance.
KEY FEATURES
Multiple personal profiles — one per family member, each with their own intolerances.
Comprehensive ingredient database — covering foods, additives, preservatives, and emulsifiers — searchable from the Explore tab.
Multilingual — works in 40 major world languages including English, French, Spanish, German, Arabic, Mandarin, Hindi, Japanese, Portuguese, Russian, Italian, Korean, Turkish and more.
Smart matching — recognizes ingredient variants across languages so the same item ("soy lecithin", "lécithine de soja", "E322") is treated as one.

No account required — your profile stays on your device.
